Compare the behavior of the particles in hot tea with the behavior of the particles in ice
cream. How are they similar? How are they different?

Answers

Answer 1

Explanation:

Absolute zero is the temperature at which particles have theoretically zero kinetic energy.

The higher temperature of the hot tea means that the water molecules in the tea will move faster on average than the water molecules in ice cream.

The general gas equation, often known as the ideal gas law, is the equation of state for a hypothetical ideal gas. It has a number of limitations, but it provides a decent approximation of the behavior of numerous gases under various circumstances.

According to the ideal gas equation,

PV =nRT

For O₂,

Number of moles of oxygen gas = 5.00 g /32 g/mol = 0.156 moles

P =?

V = 5 L

n =  0.156 moles

T = 25 + 273 = 298 K

R = 0.082 atmLK-1mol-1

P = nRT/V

P =  0.156 moles × 0.082 atmLK-1mol-1 × 298 K/5 L

P = 0.76 atm

For He,

Number of moles of He = 5/4 g/mol = 1.25 moles

P =?

V = 5 L

n = 1.25 moles

T = 25 + 273 = 298 K

R = 0.082 atmLK-1mol-1

P = nRT/V

P =1.25 moles × 0.082 atmLK-1mol-1 × 298 K/5 L

P = 6.11 atm

According to the periodic table, chlorine has an average atomic mass of 35.453 amu.

Considering that the average atomic mass of chlorine is 35.45 AMU, what is the abundance of Cl-35 and Cl-37?

Chlorine has an average atomic mass of 35.45 amu. Percent abundance for x therefore equals 77.5% and (1 - x) equals 0.225, or 22.5%. Chlorine-35 isotope abundance is 77.5%, whereas Chlorine-37 isotope abundance is 22.5%.

Mass spectrometry can be used to demonstrate that the ratio of naturally occurring chlorine isotope 35 to isotope 37 is 3 to 1.

A chlorine-35 atom has 18 neutrons in its nucleus (17 protons plus 18 neutrons), whereas a chlorine-37 atom has 20 neutrons (17 protons plus 20 neutrons = 37 particles in the nucleus). Isotopes of a substance are produced by adding or deleting neutrons from an atom's nucleus.

Answers

The partial pressure of hydrogen gas in the vessel at the end is 12 atm

How do I determine the partial pressure of hydrogen gas?

We'll begin by obtaing the new pressure of the vessel. This can be obtained as follow:

Initial pressure (P₁) = 10 atmInitial mole (n₁) = 2 + 3 = 5 molesNew mole (n₂) = 5 + 3 = 8 molesNew pressure (P₂) =?

PV = nRT

Divide both sides by V

P = nRT / V

Divide both sides by n

P / n = RT / V

RT / V => Constant

P₁ / n₁ = P₂ / n₂

10 / 5 = P₂ / 8

2 = P₂ / 8

Cross multiply

P₂ = 2 × 8

P₂ = 16 atm

Thus, the new pressure is 16 atm

Next, we shall determine the mole fraction of hydrogen gas. This is shown below:

Mole of Helium = 2 moles Mole of hydrogen gas = 3 + 3 = 6 molesTotal mole = 2 + 6 = 8 molesMole fraction of hydrogen gas =?

Mole fraction = Mole of element / total mole

Mole fraction of hydrogen gas = 6 / 18

Mole fraction of hydrogen gas = 0.75

Finally, we shall determine the partial pressure of the hydrogen gas. This can be obtained as follow:

Mole fraction of hydrogen gas = 0.75Total pressure = 16 atmPartial pressure of hydrogen gas =?

Partial pressure = mole fraction of element × total pressure

Partial pressure of hydrogen gas = 0.75 × 16

The following reaction would take place:

HCl + NH4OH+ =  NH4Cl + H2O

NaOH(aq) + NH4Cl(aq) 1  NH4OH(aq) + H2O(
