The atomic number of an atom is always equal to the total number of protons in the nucleus. Therefore, the correct answer is "protons in the nucleus".

The atomic number of an atom represents the number of protons present in the nucleus of the atom. Protons are positively charged particles, and they determine the element to which the atom belongs. The number of protons in the nucleus is equal to the number of electrons in the neutral atom, which determines the chemical properties of the element. Neutrons are uncharged particles present in the nucleus, and their number may vary for different isotopes of the same element. Therefore, the atomic number cannot be equal to the total number of neutrons in the nucleus or the total number of protons plus electrons in the atom.

Based on the observation in the warm-up activity, where the temperature of the surrounding water increased during the reaction inside the chamber, it can be inferred that the reaction released heat energy (enthalpy).

This is because the temperature of the surrounding water increased, indicating that energy was transferred from the system (reaction inside the chamber) to the surroundings (water).

According to the first law of thermodynamics, the total energy of a closed system is conserved, meaning that energy cannot be created or destroyed but can only be transferred between the system and the surroundings. In exothermic reactions, energy is released by the system to the surroundings, resulting in an increase in the temperature of the surroundings.

Therefore, the observation of an increase in temperature of the surrounding water suggests that the reaction inside the chamber is exothermic and releases heat energy.

The number of water molecules in the container when one electron is removed from every hundredth water molecule and placed in a container is 100. m from the water is 3.30 x 1025.

Given,1 liter of water = 1000 g of water1 mole of water molecules = 6.022 x 1023 particles.

Therefore, 55.5 moles of water molecules = 55.5 x 6.022 x 1023 particles = 3.33 x 1025 particles one electron is removed from every hundredth water molecule.

So, 1 electron is removed from 1% of water molecules. Therefore, the number of water molecules from which the electron is removed = (1/100) x 3.33 x 1025 = 3.33 x 1023 molecules.

Now, this electron is placed 100 m away from the water container. The distance between the water container and the electron is not relevant for finding the number of water molecules in the container, hence can be ignored.

So, the number of water molecules in the container = Total number of water molecules - number of water molecules from which electron is removed= 3.33 x 1025 - 3.33 x 1023 = 3.30 x 1025.

If you incorrectly measured your starting mass too high, the percent recovery results would be lower than they should be. This is because percent recovery is calculated as the ratio of the actual yield to the theoretical yield, multiplied by 100%.

The actual yield is the amount of product that you actually obtained from the reaction, while the theoretical yield is the amount of product that you would expect to obtain based on stoichiometric calculations.

If you measured your starting mass too high, you would have used more reactant than you should have, resulting in a larger amount of product than you would have obtained if you had used the correct amount of reactant. This means that your actual yield would be higher than it should be, while your theoretical yield would remain the same.

As a result, the ratio of actual to theoretical yield would be lower than it should be, and your percent recovery results would be underestimated.

Explanation:

a. The pressure in the compartment would be 6.7 atm at 45.0°C. b. Converting 6.7 atm to kPa gives 680.6 kPa. This is about 6.7 times greater than standard atmospheric pressure.

Converting 0.050 L to m³ gives 5.0 x 10^-5 m³.

Using the ideal gas law, we can calculate the new pressure to be 4.4 atm.

We can use the Ideal Gas Law to solve this problem, which states:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin.

a) We are given the volume V = 0.050 L, the temperature T = 45.0°C = 318.15 K, and the assumption that the compartment holds the same number of moles of N2 as in the previous question, which is n = 0.036 mol. We can rearrange the Ideal Gas Law to solve for P:

P = nRT/V

P = (0.036 mol)(0.0821 L·atm/mol·K)(318.15 K)/(0.050 L)

P = 146.7 atm

b) To convert this pressure to kPa, we can use the conversion factor 1 atm = 101.3 kPa:

P = 146.7 atm x 101.3 kPa/atm

P = 14862 kPa

To describe how many times greater than standard atmospheric pressure this would be, we can divide this pressure by standard atmospheric pressure, which is approximately 101.3 kPa:

n(C3H8) = V(P) x (P/T) x (1/mol.mass C3H8)

where V(P) is the volume of propane gas at pressure P and temperature T, and mol.mass C3H8 is the molar mass of propane (44.1 g/mol)

n(C3H8) = 0.650 L x (1 atm/1.01325 bar) x (1/273.15+25) K x (1/44.1 g/mol)

n(C3H8) = 0.0153 mol

Therefore, the amount of oxygen required for complete combustion of propane is:

n(O2) = 5 x n(C3H8)

n(O2) = 5 x 0.0153 mol

n(O2) = 0.0765 mol

To find the volume of oxygen required, we can use the ideal gas law:

PV = nRT

where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the gas, R is the gas constant, and T is the temperature of the gas in Kelvin.

Rearranging the equation and plugging in the values, we get:

V(O2) = n(O2)RT/P

where R is the gas constant (0.08206 L atm mol^-1 K^-1) and T is the temperature in Kelvin (298 K)

V(O2) = 0.0765 mol x 0.08206 L atm mol^-1 K^-1 x 298 K / 1 atm

V(O2) = 1.86 L

Therefore, 1.86 L of oxygen is required to completely combust 0.650 L of propane.

To find the volume of carbon dioxide produced, we use the same approach:

n(CO2) = 3 x n(C3H8)

n(CO2) = 3 x 0.0153 mol

n(CO2) = 0.0459 mol

V(CO2) = n(CO2)RT/P

where R is the gas constant (0.08206 L atm mol^-1 K^-1) and T is the temperature in Kelvin (298 K)

V(CO2) = 0.0459 mol x 0.08206 L atm mol^-1 K^-1 x 298 K / 1 atm

V(CO2) = 1.08 L

Therefore, 1.08 L of carbon dioxide is produced in the reaction.

If the compartment could retain the same quantity of moles of N2 gas as determined in the previous question at a temperature of 45.0°C, the pressure inside would be 28.6 atm.

P = nRT/V

replacing the specified values:

P = 28.6 atm when P = (0.0122 mol)(0.0821 L atm/mol K)(45.0°C + 273) / 0.050 L.

We can use the following conversion factor to change this pressure from kPa to atm:

101.325 kPa per atm

Therefore, the pressure in kPa is 2899 kPa: 28.6 atm x 101.325 kPa/atm

To put it in terms of how much higher than normal atmospheric pressure this would be:

28.6 times (2899 kPa / 101.325 kPa)

As a result, there would be an increase in pressure of 28.6 times inside the container.

A solution is made by dissolving 19.8 g of Compound AB in enough water to create a 115.1 ml solution. The solution's density is: 1.14 g/mL.

The formula for the molality of a solution is m = moles of solute/mass of solvent in kilograms.

To begin, we must first convert the solution's density to mass by using the density formula: density = mass/volume

Mass = density x volume

Mass = 1.14 g/mL x 115.1 mL

Mass = 131.214 g

Next, we must convert grams to kilograms for the mass of the solvent in the molality formula by dividing the mass by 1000.

Mass of solvent in kilograms = 131.214 g / 1000

Mass of solvent in kilograms = 0.131214 kg

Finally, we must calculate the moles of solute, which is Compound AB. To do so, we must use the compound's molar mass, which is calculated by adding up the atomic weights of each element present in the compound. We'll use the following calculations to find the molar mass of Compound AB.

Molar mass of Compound AB = 1 mol A + 1 mol B= 35.5 g/mol A + 79.9 g/mol B

Molar mass of Compound AB = 115.4 g/mol

Now that we have the molar mass of Compound AB, we may calculate the number of moles of solute by dividing the mass by the molar mass.

Number of moles of solute = 19.8 g / 115.4 g/mol

Number of moles of solute = 0.1716 mol

Now that we have the moles of solute and the mass of solvent in kilograms, we can plug in our values to the molality formula to obtain the solution's molality.

m = moles of solute/mass of solvent in kilograms

= 0.1716 mol / 0.131214 kgm = 1.306 mol/kg

The molality of the AB solution is 1.306 mol/kg.

The correct option is A) Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

The assertion is that atomic size decreases across a period and increases down a group of the periodic table.

The assertion is correct because, moving from left to right across a period, the atomic number of elements increases, resulting in an increase in the number of protons in the nucleus, which attract the electrons closer to the nucleus, reducing the atomic size. Additionally, as electrons are added to the same valence shell, there is no significant increase in the shielding effect of inner shells, which further decreases the atomic size.

The reason is also correct because, as we move down a group, the number of electron shells increases, and the atomic size increases because of the increasing distance between the outermost electrons and the nucleus. The electrons in inner shells also provide more shielding, reducing the effective attraction of the nucleus on the outermost electrons, further increasing the atomic size.

The volume of the balloon at the new pressure and temperature will be approximately 0.721 L.

This is a problem involving the ideal gas law, which relates the pressure, volume, number of moles, and temperature of a gas:

PV = nRT

where P is pressure, V is volume, n is number of moles, R is  ideal gas constant, and T is temperature in Kelvin.

We can use this equation to solve for the final volume of the balloon at a different pressure and temperature, assuming that the number of moles of gas remains constant.

Firstly, we need to convert temperature to Kelvin:

T₁ = 273.15 + 15 = 288.15 K

T₂ = 273.15 - 50 = 223.15 K

Next, we can rearrange the ideal gas law equation to solve for the final volume:

V₂ = (nRT₂)/P₂

where P₂ is the new pressure.

To find the new pressure, we can use the ideal gas law equation with the given conditions:

P₁V₁ = nRT₁

Solving for P₁:

P₁ = (nRT₁) / V₁

P₁ = (6.112 mol)(0.0821 L·atm/mol·K)(288.15 K) / (2.29932 L)

P₁ = 16.2 atm

Now we can use the new pressure and temperature to calculate the final volume:

V₂ = (nRT₂)/P₂

V₂ = (6.112 mol)(0.0821 L·atm/mol·K)(223.15 K) / (16.2 atm)

The relationship between pressure and volume of a gas is Inverse, so that as volume decreases, pressure increases. The relationship between pressure and volume of a gas is called the Boyle's Law.

According to this law, at a constant temperature and amount of gas, the pressure and volume of a gas are inversely proportional to each other i.e. PV = K where P is the pressure, V is the volume, and K is a constant. So, as the volume of a gas decreases, the pressure increases, and as the volume of a gas increases, the pressure decreases.

This can be explained by the fact that as the volume decreases, the molecules of gas are compressed into a smaller space, which causes them to collide more frequently with each other and the walls of the container. This increase in collisions results in an increase in pressure. Conversely, as the volume increases, the molecules of gas have more space to move around and collide less frequently, resulting in a decrease in pressure.
