Explanation:

Someone Please Help Me Pass My Chem Class!!! 5.000 Moles Of An Ideal Gas Occupies 10.00 Liters At A Temperature
Answer 2

Using the ideal gas law equation PV = nRT, and by converting the temperature to Kelvin, the pressure of the ideal gas is calculated to be 11.08 atmospheres.

The question pertains to the calculation of the pressure of an ideal gas given a certain amount of moles, volume, and temperature. To find the pressure on the gas, we use the ideal gas law equation PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in kelvins.

First, we convert the temperature from Celsius to Kelvin: T(K) = -3.000 "+ 273.15 = 270.15 K.

We then use the value for R when pressure is in atmospheres, which is 0.0821 L  imes atm/(K  imes mol). With the given volume of 10.00 liters and the amount of 5.000 moles, the calculation is as follows:

P = (nRT)/V

P = (5.000 mol  imes 0.0821 L  imes atm/(K  imes mol)  imes 270.15 K) / 10.00 L

P = 11.08 atm

Thus, the pressure on the gas is 11.08 atmospheres, which corresponds to option (c).

5. How can you describe the specific heat of olive oil if it takes approximately 420 J of heat to raise the
temperature of 7 g of olive oil by 30°C?
Not enough information is given.
greater than the specific heat of water
c. less than the specific heat of water
equal to the specific heat of water

Answers

Answer:

Lower than the specific heat capacity of water

Explanation:

Specific heat capacity of a material is defined as the amount of heat needed to raise 1 g of that substance by [tex]1^oC[/tex]. Specific heat capacity is typically used in the equation which relates heat transfered to the product of specific heat capacity, mass and change in temperature, given by:

[tex]Q = cm\Delta T[/tex]

In this problem:

[tex]Q = 420 J[/tex]

[tex]m = 7 g[/tex]

[tex]\Delta T = 30^oC[/tex]

We may simply rearrange this equation for specific heat, c, in order to solve for its value:

[tex]c = \frac{Q}{m\Delta T} = \frac{420 J}{7 g\cdot 30^oC} = 2 \frac{J}{g^oC}[/tex]

We know that the specific heat capacity of water is:

[tex]c_w = 4.184 \frac{J}{g^oC}[/tex]

The value we obtained is lower than the specific heat capacity of olive oil.

Final answer:

The specific heat of olive oil is approximately 2 J/g °C, which is less than the specific heat of water.

Explanation:

The specific heat of olive oil can be calculated by using the formula: q = mcΔT, where q is the heat energy absorbed, m is the mass of the substance, c is the specific heat, and ΔT is the change in temperature. In this case, we are given the heat (q) as 420 J, the mass (m) as 7 g, and the change in temperature (ΔT) as 30 °C. Plugging these values into the formula, we get 420 J = c * 7 g * 30 °C. Solving for c, we find that the specific heat of olive oil is approximately 2 J/g °C.

Comparing this specific heat value to the specific heat of water, which is 4.184 J/g °C, we can conclude that the specific heat of olive oil is less than the specific heat of water.

how are complete ionic and net ionic equations written for chemical reactions in aqueous solutions

The ClO₂⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.

What can you tell by tracking oxidation numbers?

Answers

Answer:

By tracking oxidation numbers we can identify the number electron in the atom

Explanation:

Tracking of electrons helps us to know when and how many electrons get transferred from one atom to other atom . Oxidation  referred as the “loss of one or more electrons” by an atom. When the oxidation number of an element increases, there is a loss of electrons and that element is being oxidized. Oxidation numbers are usually written with the sign (+plus or −minus) followed by the magnitude, which is the opposite of charges on ions. In their elemental stage oxidation number of an atom is zero.  

Final answer:

Oxidation numbers are used to track electrons in atoms. By assigning oxidation numbers based on certain rules, we can determine what is being oxidized and what is being reduced in a redox reaction.

Explanation:

Oxidation numbers are used to keep track of electrons in atoms. They are assigned to atoms based on four rules. Oxidation is an increase in oxidation number (loss of electrons), while reduction is a decrease in oxidation number (gain of electrons). By tracking oxidation numbers, we can determine what is being oxidized and what is being reduced in a redox reaction. For example, in the reaction where carbon reacts with oxygen to form carbon dioxide, the oxidation number of carbon changes from zero in the reactants to +4 in the product, indicating that carbon is being oxidized. On the other hand, the oxidation number of oxygen changes from zero to -2, indicating that oxygen is being reduced.

Which of the following will have the highest electronegativity? Silicon (Si), Phosphorus (P) or Arsenic (As). Explain your
answer

Answers

Answer:

Phosphorus

Explanation:

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction and electronegativity increases.

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus electronegativity decreases.

Silicon is present in group 4A and Phosphorus and Arsenic is present in group 5A thus electronegativity of silicon is less than Phosphorus and arsenic. Arsenic is present down to phosphorus thus its electronegativity will less than phosphorus.

P = 2.19

Si = 1.9

As = 2.18

How would adding the catalyst nitrogen monoxide (NO) affect this reaction? 2SO2(g) + O2(g) → 2SO3(g)

Answers

Answer:

NO decreases the activation energy and increases the rate of a reaction

Explanation:

To fully comprehend this problem, we wish to understand the role of a catalyst in a chemical reaction. Catalyst is a substance which is essentially consumed and then reproduced (that said, its mass remains the same and the net mass consumed is equal to 0) in a chemical reaction which:

decreases the activation energy barrier – that is, the minimum amount of energy required for a successful collision between molecules leading to a chemical reaction;increases the rate of a reaction: the reaction proceeds faster. This is achieved based on the fact that the activation energy is decreased.

Addition of a nitrogen monoxide catalyst would therefore decrease the activation energy and increase the rate of a reaction.

Now, in terms of equilibrium (if the reaction is at equilibrium, as just a right arrow is indicated), since nitrogen monoxide is a gas, there would be no shift in equilibrium towards the products or reactants, as addition of an inert gas to an equilibrium system would decrease the partial pressures of each component equally.

They require only one electron to complete their outer shell

Explanation:

The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their high reactivity is due to the presence of seven valance electrons. They need just one electron to complete the octet that's why they can not found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements. Their boiling points also increases down the group which changes their physical states. i.e fluorine is gas while iodine is solid.

Consider the example of sodium chloride. Chlorine accept one electron from sodium and complete the octet.

The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between them and both get complete complete octet.

An airplane attempting to fly higher than 300,000 feet will

Answers

Answer:

Begin to succumb to the power of gravity because of the decrease in lift

Explanation:

Final answer:

An airplane climbing to altitudes higher than 300,000 ft would struggle with decreased lift due to lower air density and would not necessarily require an extra engine. Engines produce less power with increased altitude, so the airplane must efficiently use its existing engines to maintain climb without compromising lift. So the correct option is D.

Explanation:

When an airplane attempts to fly higher than 300,000 ft, it would not typically need an extra engine but will begin to succumb to the power of gravity because of the decrease in lift, that is, option D. At such altitudes, the air density is much lower, meaning there is less air to generate lift. Indeed, for straight and level flight, an aircraft must maintain a balance where the thrust equals the drag. As the airplane ascends, the air becomes thinner (density altitude increases), and to maintain the same lift, the aircraft would need to travel at higher speeds or have a greater angle of attack. However, the engines' efficiency also decreases with altitude, as they are designed to operate optimally within certain atmospheric conditions.

Furthermore, jet engines, like turbojets, produce less power at higher altitudes due to the reduced air density. Thrust from engines does not counteract drag by increasing the number of engines but by optimizing performance of existing engines. To climb and maintain velocity, aircraft need to produce enough excess power to convert that energy into increased potential energy without compromising the energy needed for maintaining lift.

The student needs to understand that the trade-off between kinetic and potential energy in an aircraft is similar to a car climbing a hill. To increase altitude without losing speed, additional power is required to offset the energy directed towards increasing altitude. Thus, the aircraft must be capable of generating the additional power needed to climb, which becomes more challenging as altitude increases.

Some kinds of matter are attracted to a magnet. Is this a physical or chemical property of matter?

Answers

Answer:

Physical Property

Explanation:

Magnetism is temporary untill you seperate the objects. There is no chemical change involved before, after, or during.

The attraction of certain materials to a magnet is a physical property of matter because it doesn't involve a change in the chemical composition of the material but rather relates to the arrangement and behavior of its electrons.

The attraction of certain types of matter to a magnet is a physical property of matter. Physical properties are characteristics of a substance that can be observed or measured without altering the substance's chemical composition. Magnetism is one such property that describes a material's ability to be attracted to or repelled by a magnet.

The phenomenon of magnetism arises from the alignment and behavior of the electrons in the atoms or molecules of a material. Materials that exhibit magnetic properties have domains where the magnetic moments of the individual atoms or molecules align in a particular direction. When exposed to an external magnetic field, these domains can align with the field, causing the material to be attracted to the magnet.

Importantly, this attraction is reversible and does not involve a change in the material's fundamental chemical composition. When the magnetic field is removed, the material returns to its original state. Common magnetic materials, such as iron, nickel, and cobalt, have unpaired electrons in their electron configurations, which allows them to exhibit strong magnetic properties.

In contrast, chemical properties of matter involve changes in the chemical composition of substances, such as reactions that form new compounds or alter the arrangement of atoms within molecules.

Which happens when a reversible reaction reaches a state of chemical equilibrium?

Answers

Explanation:

Reversible reactions that happen in a closed system eventually reach equilibrium. At equilibrium, the concentrations of reactants and products do not change. But the forward and reverse reactions have not stopped - they are still going on, and at the same rate as each other.

Every reaction strives to reach a state of chemical equilibrium, which is the point where both the forward and backward processes are occurring at the same pace. The concentrations of the reactants and products are constant at equilibrium because the forward and reverse speeds are equal.

What is chemical equilibrium ?

Chemical equilibrium is the state of a chemical process where both the reactants and products are present in concentrations that have no further tendency to change over time, preventing any discernible change in the system's properties.

When a chemical reaction is reversible, equilibrium is reached when the rate at which the forward reaction is moving equals the rate at which the reverse reaction is moving.

Even though the two reactions proceed at equal but opposite rates, there are no additional changes in the reactant and product concentrations. At some point, the forward and reverse reaction rates are identical; the rate at which reactants transform into products is the same as the rate at which products transform into reactants.

Thus, Every reaction strives to reach a state of chemical equilibrium, which is the point where both the forward and backward processes are occurring at the same pace.

Explanation:

The given elements are present in group 5th A in Following order:

N

Sb

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

Thus antimony have largest atomic radius.

Out of the four options, Sb has the highest atomic radius.
