Unlike clouds, fog, or mist which are simply suspended particles of liquid water in the air, water vapour itself cannot be seen because it is in gaseous form. Water vapour in the atmosphere is often below its boiling point. When water is boiled the water evaporates much faster and makes steam.

Both vapor and gas contains the gaseous molecules. But vapor state contains a second phase too along with gas whereas, gaseous state only contain one component.

Vapor is a state of matter consists of two component. Solid and gas  or liquid and gas. Thus vapor is formed when a gas comes in contact with liquid or solid.

There forms an equilibrium between gaseous state and liquid or solid state. For example water forms water vapor when the liquid water boils to form gases, similarly other liquids such as acids forms their vapor.

Gases such as oxygen, hydrogen, nitrogen etc.  forms only gases and thus have only one component. Thus we used to say nitrogen gas, hydrogen gas etc.

Therefore, vapor is a combination of two states and gas in a single state. Water forms vapor and can be called water vapor but nitrogen is called gas only.

Final answer:

To find the mass of 0.750 mol of Na3PO4, calculate the molar mass by summing the atomic masses of Na, P, and O, and then multiply the molar mass by the number of moles. The mass is found to be 122.955 g.

Explanation:

To calculate the mass of 0.750 mol of Na3PO4, we first need to determine its molar mass. We sum the atomic masses of all the atoms in the compound:

Na (Sodium) has an atomic mass of 22.99 g/mol, and there are 3 Na atoms.

P (Phosphorus) has an atomic mass of 30.97 g/mol, and there is 1 P atom.

O (Oxygen) has an atomic mass of 16.00 g/mol, and there are 4 O atoms.

The molar mass of Na3PO4 is thus calculated as:

(3 × 22.99 g/mol) + (1 × 30.97 g/mol) + (4 × 16.00 g/mol) = 163.94 g/mol

Now, to find the mass of 0.750 mol of Na3PO4, we use the formula:

Mass = moles × molar mass

Mass = 0.750 mol × 163.94 g/mol = 122.955 g of Na3PO4

The correct answer is C. Atoms are made up of smaller particles.

Explanation:

John Dalton was an English chemist and physicist mainly known for proposing one of the first formal theories related to atoms by the end of the 19th century. In this theory, Dalton explained atoms were the basic unit for all elements and cannot be divided into smaller participles, also he proposed atoms of the same elements are identical including their masses and those of different elements are different. This means the statement that is not part of Dalton's atomic theory is "Atoms are made up of smaller particles" because for Dalton atoms are the smallest unit and cannot be divided into smaller parts, this was proved as false later as they can be divided into sub-particles.

Intermolecular forces in solids are strongest than in liquids and gases. Gases have the least strong intermolecular forces. Intermolecular forces are weak and are significant over short distances between molecules (determined by Coulomb’s law). The farther away from the molecules the weaker the intermolecular forces. Since molecules in solids are the closest, the intermolecular force between them as the strongest. Conversely, since gas molecules are farthest apart, the intermolecular forces between them are the weakest.

The strength of intermolecular forces varies in solids, liquids, and gases. They are strongest in solids, due to which molecules or atoms are tightly packed. In gases, they are the weakest, allowing for a greater separation of atoms or molecules. Certain factors like the size and identity of the molecules also influence these forces.

Intermolecular forces refer to the attractions between molecules, which determine many of the physical properties of a substance. In solids, liquids, and gases, the strength of these forces varies significantly. In gases, the atoms and molecules are more separated, and intermolecular forces can be almost ignored. On the other hand, in liquids, these forces are strong enough to keep the molecules in contact, but not to prevent them from moving past each other. However, in solids, the intermolecular forces are so strong that the molecules or atoms are tightly packed, making them resistant to changing their shape or volume.

It's important to note that larger and heavier atoms and molecules exhibit stronger dispersion forces (a type of intermolecular force) than smaller and lighter ones. Hence, molecules like F2 and Cl2 are gases at room temperature indicating weaker intermolecular forces, while Br2 is a liquid, and I2 is a solid, representing stronger intermolecular forces. The identity of the molecules also determines the type and strength of the intermolecular attractions possible. Thus, strong intermolecular forces impede vaporization and favor the 'recapture' of gas-phase molecules, resulting in a lower vapor pressure, and vice versa.

Explanation:

Properly writing the equation we have:

       ²³⁹₉₄Pu → ᵃₙX + ⁴₂He

The unknown atom here is X with mass number "a'' and atomic number ''n''

In balancing chemical equations, the mass number and atomic number must be conserved. This implies that the sum of atomic numbers i.e subscript on the left hand side must be equal to that on the right hand side. Also, the sum of the mass numbers i.e superscript on the left hand side must be equal to that on the right hand side.

For the mass numbers:

       239 = a + 4

      a = 239 - 4 = 235

For atomic numbers:

     94 = n + 2

      n = 94 -2 = 92

The atom X, has a mass number of 235 and an atomic number of 92.

An atom becomes an ion to achieve electrical stability. This can occur either by the atom losing electrons and becoming a cation (positive ion), or gaining electrons and becoming an anion (negative ion). This process, known as ionization, typically happens during chemical reactions.

An atom may become an ion in pursuit of electrical stability. Atoms are originally neutral, containing equal numbers of protons (positive charge) and electrons (negative charge). Certain atoms become more stable by gaining or losing electrons, altering the balance between protons and electrons and creating a net charge, thereby becoming ions.

There are two types of ions: cations and anions. Cations are positive ions that form when an atom loses electrons. For instance, a sodium atom (Na) could lose one electron to become a cation (Na+). On the other hand, anions are negative ions formed when an atom gains electrons. For example, an oxygen atom could gain two electrons to become an anion (O2-).

The process where an atom gains or loses electrons to form ions is known as ionization. This atomic transformation usually occurs during chemical reactions, especially in the formation of ionic bonds.

To calculate the heat absorbed by the water, we use the formula Q = mcΔT, where Q represents the heat energy absorbed, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Substituting the given values, we find that approximately 136,872 joules of heat are absorbed to raise the water's temperature from 25°C to 100°C.

This question is asking how much heat energy, in joules, is required to heat 435 grams of water from 25°C to 100°C at atmospheric pressure. The formula used to calculate this is Q = mcΔT, where Q represents the heat energy absorbed, m is the mass of the substance (water), c is the specific heat capacity, and ΔT is the change in temperature.

For water, the specific heat capacity (c) is 4.184 J/g°C. The mass (m) of the water is given as 435 g. The change in temperature (ΔT) is the final temperature minus the initial temperature, which is 100°C - 25°C = 75°C.

Substituting these values into the equation gives us, Q = (435 g) × (4.184 J/g°C) × (75°C), which equals approximately 136,872 joules. This is amount of heat absorbed by the water to raise its temperature from 25°C to 100°C at 1 atm.

Answer:the empirical formula is C3H8O2

Explanation:

You need to determine the relative number of moles of hydrogen and carbon. So you first calculate the molar mass of CO2 and H20 Atomic weight of carbon = 12.0107 Atomic weight of hydrogen = 1.00794 Atomic weight of oxygen = 15.999 Molar mass CO2 = 12.0107 + 2 * 15.999 = 44.0087 Molar mass H2O = 2 * 1.00794 + 15.999 = 18.01488 Now calculate the number of moles of CO2 and H2O you have Moles CO2 = 2.086 g / 44.0087 g/mole = 0.0474 mole Moles H2O = 1.134 g / 18.01488 g/mole = 0.062948 mole Calculate the number of moles of carbon and hydrogen you have. Since there's 1 carbon atom per CO2 molecule, the number of moles of carbon is the same as the number of moles of CO2. But since there's 2 hydrogen atoms per molecule of H2O, The number of moles of hydrogen is double the number of moles of H2O Moles Carbon = 0.0474 Moles Hydrogen = 0.062948 * 2 = 0.125896 Now we need to determine how much oxygen is in the compound. Just take the mass of the compound and subtract the mass of carbon and hydrogen. What's left will be the mass of oxygen. Then divide that mass by the atomic weight of oxygen to get the number of moles of oxygen we have. 1.200 - 0.0474 * 12.0107 - 0.125896 * 1.00794 = 0.503797 Moles oxygen = 0.503797 / 15.999 = 0.031489 So now we have a ratio of carbon:hydrogen:oxygen of 0.0474 : 0.125896 : 0.031489 We need to find a ratio of small integers that's close to that ratio. Start by dividing everything by 0.031489 (selected because it's the smallest value) getting 1.505288 : 3.998095 : 1 The 1 for oxygen and the 3.998095 for hydrogen look close enough. But the 1.505288 for carbon doesn't work. But it looks like if we double all the numbers, we'll get something close to an integer for everything. So do so. 3.010575 : 7.996189 : 2 Now this looks good. Rounding everything to an integer gives us 3 : 8 : 2 So the empirical formula is C3H8O2
