1. An acetic acid solution that is 60.0% HC2H302 (by mass) contains
60.0 g acetic acid and 100.0 g water
60.0 g acetic acid and 40.0 g water
60 moles of acetic acid
60.0 g acetic acid and 60.0 g water

Answers

Answer 1

Answer:

The correct answer is: 60.0 g acetic acid and 40.0 g water

Explanation:

The percentage in mass (% by mass) is expressed as follows:

% by mass = % m/m = grams of solute/100 g solution

If the solution of acetic acid is 60.0% by mass, that means that there are 60 grams of solute (acetic acid) in 100 grams of solution. Besides, a solution is composed by solute and solvent (water). If there are 60 grams of solute, there are 40.0 grams of solvent (water) in 100 grams of solution.

So, the solution contains 60.0 g acetic acid and 40.0 g water.

Concentrated HCl is 98% and has density 1.46g/cm 3 what volume of
concentrated acid required to make 2L of 0.25M HCl .

Answers

Answer:

12.64 cm^3 to the nearest hundredth

Explanation:

1 L of 0.25M of HCl contains 0.25 * (1.008 * 35.45) g of HCl

= 9.1145 g HCl.

So 2 litres contain 18.229 g HCl.

So we need the volume of concentrated acid which contains 18.229 g HCl.

1.46 * 0.98 = 1.4308 g are in  1 cm^3

So 18.229 g are in  18.229/1.4308

= 12.6404 cm^3 (answer).

Explanation:

Using the equation, what is the mass of lithium nitride is produced from 12.26 L of ammonia?

Answers

Answer:

19.2g

Explanation:

The equation of the reaction is;

Li3N(s) +3H2O(l) ---->NH3(g) +3LiOH(aq)

From Avogadro's law we know that 1 mole of any gas occupies a volume of 22.4 L under standard conditions.

It is also clear from the equation that 1 mole of lithium nitride produces 1 mole of ammonia occupying 22.4L volume

Hence;

1 mole of Lithium nitride yields 22.4 L of ammonia

x moles of lithium nitride yields 12.26L of ammonia

x= 12.26×1/22.4

x= 0.55 moles of lithium nitride

Molar mass of lithium nitride= 34.83 g/mol

Mass of lithium nitride = number of moles × molar mass

Mass of lithium nitride= 0.55 moles × 34.83 g/mol

Mass of lithium nitride = 19.2g

Answer:

The mass of lithium nitride that produces 12.26 L of ammonia is 19.053 g

The mass of lithium hydroxide produced is 39.3 g

Explanation:

Water and Lithium nitride combine to form ammonia and lithium hydroxide the  equation for the reaction being;

Li₃N(s) + 3H₂O(l) → NH₃ (g)  + 3LiOH (aq)

That is 1 mole of lithium nitride combines with 3 moles of water molecules to form 1 mole of ammonia gas plus 3 moles of lithium hydroxide

Whereby the volume of ammonia produced is 12.26 L, we have at STP

PV = nRT

Therefore, n = PV/RT

Where:

P = Pressure = 1 atm

V = Volume = 12.26 L

R = Universal gas constant = 0.08205 L·atm/(mol·K)

T = Temperature = 273.15 K

Plugging the values in gives;

n = (1×12.26)/(0.08205×273.15) = 0.547 moles

Since 1 mole of lithium nitride forms 1 mole of NH₃, 0.547 mole will be required to produce 0.547 moles of NH₃ and 3×0.547 or 1.64 moles of LiOH

Molar mass of Li₃N = 34.83 g/mol

Molar mass of LiOH = 23.95 g/mol

Since mass = Number of moles × molar mass, we have;

Mass of Li₃N = 0.547 × 34.83 = 19.053 g  

Mass of LiOH = 1.64 × 23.95 = 39.3 g

Therefore;

The mass of lithium nitride that produces 12.26 L of ammonia = 19.053 g

The mass of lithium hydroxide produced = 39.3 g.

What is the hydrogen ion concentration of a substance with a pH of 4.5?​

Answers

Answer:

The hydrogen ion concentration of the substance is 3.16*10⁻⁵ M

Explanation:

pH is a parameter used to measure the degree of acidity or alkalinity of a substance. The pH is calculated as the negative logarithm (base 10) of the concentration of hydronium ions [H₃O⁺] or hydrogen ions [H⁺].

pH= - log [H₃O⁺]= - log [H⁺]

Values ​​on the pH scale range from 0 to 14, where pH equal to 7 is neutral, below 7 is acidic and above 7 is basic.

In this case, pH= 4.5

So:

4.5= - log [H⁺]

Solving:

[ H⁺]= 10⁻⁴ ⁵

[H⁺]= 3.16*10⁻⁵ M

The hydrogen ion concentration of the substance is 3.16*10⁻⁵ M

A common isotope of iron (Fe) has an atomic number of 26 and a mass number
of 56. The total number of subatomic particles in the nucleus is: *
26

Answers

Answer:

82

Explanation:

Atomic number of the isotope is 26 and it has a mass number of 56

X = ⁵⁶₂₆Fe

The three main subatomic particles in an atom are

1. Proton

2. Neutron

3. Electron

The number of protons and electrons are usually equal so as to maintain electrical neutrality in the atom except in cases where it's a charged particles hence the number of proton and electrons will differ.

In this case, the atomic number is 26 and atomic numbers are also known as the number of protons (positively charged particle).

Proton = 26

Electrons = 26 (since it's a naturally charged particle)

Neutron = ?

Mass number = sum of proton and neutrons. This variation in the mass number usually leads to isotopes of an atom and this is mainly caused by variation in the number of neutrons eg. Carbon-12 and Carbon-13 have different number of neutrons.

Mass number = protons + neutrons

Neutrons = mass number - protons

Neutrons = 56 - 26

Neutrons = 30

Subatomic particles present are

Protons = 26

Electrons = 26

Neutrons = 30

Total number = (26 + 26 + 30) = 82

The total number of subatomic particles is 82.

Final answer:

The total number of subatomic particles in the nucleus of this common isotope of iron (with an atomic number of 26 and a mass number of 56) is the sum of protons and neutrons, which is 56.

Explanation:

An isotope is a variant of an element that has the same number of protons (which is the atomic number) but differs in the number of neutrons. The atomic number of iron (Fe) is 26, which reflects the number of protons in the nucleus. The mass number (56) is the combined total of protons and neutrons in the nucleus. Since we know there are 26 protons (from the atomic number), the remainder must be neutrons. So, 56 (mass number) minus 26 (atomic number) gives us 30 neutrons.

Therefore, the total number of subatomic particles in the nucleus of this isotope of iron is 26 (protons) + 30 (neutrons) = 56 particles in total.

When Holly injures her shoulder playing baseball, she uses an instant ice pack to reduce the swelling. She breaks the inner, activator portion of the instant cold pack releasing the solid urea into the surrounding water. What process does Holly observe as she uses the cold pack? A) Urea absorbs and releases heat energy into the surroundings. B) When the urea dissolves it absorbs heat and the cold pack gets colder. C) The urea causes the surroundings heat up as the cold pack releases energy. D) As the urea mixes in the water it releases heat making the cold pack colder.

Answers

Answer:

B) When the urea dissolves it absorbs heat and the cold pack gets colder.

Explanation:

Cold packs usually contains two bags, one contains a water and the other inside is a form of ammonium nitrate  as the solid (s) or urea.

Breaking the inner portion activates the instant cold pack thereby releasing the solid urea into the surrounding water makes the urea to react with the water and makes it cold. This is because the reaction that takes place then undergoes an endothermic reaction, Hence heat is absorbed from the surroundings and the cold pack gets colder

Final answer:

The cold pack gets colder as a result of an endothermic reaction where urea dissolves in water and absorbs heat from the surroundings.

Explanation:

When Holly activates her instant ice pack by breaking the inner compartment, she initiates an endothermic reaction in which the solid urea dissolves in water. During this endothermic dissolution, the urea absorbs heat energy from the surrounding environment, which includes Holly's injured shoulder. This absorption of heat causes the temperature of the pack and the surrounding area to decrease, thus the pack feels cold to the touch. Therefore, the process that Holly observes as she uses the cold pack is B) When the urea dissolves it absorbs heat and the cold pack gets colder.

Answers

Answer: [tex]Rate=\frac{\Delta_{\text {reactants or products}}}{\Delta_{time}}[/tex]

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

Rate of reaction can be defined in terms of reactants or products. It is the ratio of disappearance of reactants per unit time or ratio of appearance of products per unit time.

[tex]Rate=\frac{\Delta_{reactants}}{\Delta_{time}}[/tex] or [tex]Rate=\frac{\Delta_{products}}{\Delta_{time}}[/tex]

[tex]S_{products}-S_{reactants}[/tex] gives the entropy change for the reaction.

Final answer:

Chemical kinetics equation for reaction rates and how rates of reactions depend on reactant and product concentrations.

Explanation:

Reaction rates in chemical kinetics are described by the equation: rate = k[A]m[B]n , where k is the rate constant, m and n are exponents determined experimentally, and m+n is the reaction order.

The rate of a chemical reaction can be expressed as the change in concentration of reactants or products over time. In general, the rate of reaction depends on the concentration of reactants or products involved in the reaction.

For a net forward reaction under rapid equilibrium conditions, the rate equation can be derived and expressed in terms of concentrations of reactants and products.

Thomson discovered that cathode rays, which were later identified as streams of electrons, were deflected by electric and magnetic fields in a way that indicated they had a negative charge. Furthermore, based on the amount of deflection, Thomson was able to deduce that electrons had far less mass than atoms, leading to the conclusion that electrons are much smaller than the nucleus.

A car has initial velocity of 50 m/s and a constant acceleration of 50 m/s2, whats the car velocity after 3 seconds?

Answers

Answer:

200 m/s.

Explanation:

The car's velocity after 3 seconds can be calculated using the kinematic equation:

v= u+ at

Given:

- Initial velocity, u = 50m/s

- Acceleration, a = 50m/s2

- Time, t = 3 s

Plugging the values into the equation:

v = 50 + 50 * 3

v = 50 + 150

v = 200 m/s

Therefore, the car's velocity after 3 seconds will be 200 m/s. Hope this helps!!

The car's velocity after 3 seconds is 200 m/s, calculated using the formula for final velocity with an initial velocity of 50 m/s and an acceleration of 50 m/s².

To find the final velocity of a car with an initial velocity and constant acceleration, you can use the formula v = u + at, where v is final velocity, u is initial velocity, a is acceleration, and t is time.

In this case, the car has an initial velocity (u) of 50 m/s and a constant acceleration (a) of 50 m/s². After 3 seconds (t), we can calculate the final velocity using the formula:

v = u + at
v = 50 m/s + (50 m/s² × 3 s)
v = 50 m/s + 150 m/s
v = 200 m/s

Therefore, the car's velocity after 3 seconds is 200 m/s.

Final answer:

The elements on the periodic table that form cations in ionic compounds are primarily found in the alkali metals (group 1), alkaline earth metals (group 2), transition metals  and the representative metals. These elements lose electrons to achieve a stable electron configuration and form cations with positive charges.

Explanation:

The areas of the periodic table that contain elements which form cations in ionic compounds are primarily the groups that contain metals. These are the alkali metals (group 1), alkaline earth metals (group 2) and transition metals (groups 3-12). These elements lose electrons and form cations with positive charges. For example, an atom of an alkali metal like sodium (Na) loses one electron and forms a cation with a 1+ charge.

Transition elements and post-transition metals can also form cations in ionic compounds. Although their charges can vary, they often lose electrons to achieve a stable electron configuration.

These are termed as representative metals, including aluminum, zinc, and tin, which can exhibit different positive charge magnitudes based on their group and period. For instance, aluminum (Al) from group 13, and zinc (Zn) from group 12, commonly lose 3 and 2 electrons respectively to form cations.
