Answer:
- <u>Freezing point: - 1.83ºC</u>
- <u>Boiling point: 100.50ºC</u>
Explanation:
The <em>freezing point</em> and<em> boiling point</em> of solvents, when a solute is added, will change accordingly to the concentration of the solute particles.
The freezing point will decrease and the boiling point will increase. These are two colligative properties.

The total pressure of the mixture of gases is equal to the sum of the pressure of each gas as if it is alone in the container. The partial pressure of a component of the mixture is said to be equal to the product of the total pressure and the mole fraction of the component in the mixture.
Partial pressure of hydrogen gas = 1.24 atm x .25 = 0.31 atm
Partial pressure of the remaining = 1.24 atm x (1-.25) = 0.93 atm
I believe the answer is D
Answer:
Tile 52 and three are incorrect
Explanation:
The concentrations of reactants and the products are not constant and the rates of the forward and reverse reactions are equal. and these reactions are not at equilibrium.
<u>Explanation:</u>
The conditions to attain equilibrium is that,
- Conversion of reactant to product and vice versa occurs at the same rate.
- The system is a closed system.
- The temperature remains constant.
- Concentration of every substance remains constant.
- Rate of forward and reverse reactions will be different.
So the answer is The concentrations of reactants and the products are not constant and the rates of the forward and reverse reactions are equal.
