when 32.4 g of water vapor condenses, how much heat is given off? The heat of vaporization for water is 40.67 kj/mol

1 answer:

3 0

When a water vapor condenses, heat is being released from the process. This heat is called latent heat of vaporization since the phase change happens without any change in the temperature. This value is constant per mole of a substance as a function of pressure and temperature. For this problem, we are given the heat of vaporization at a certain T and P. We use this value to calculate the total heat released from the process. We calculate as follows:

Total heat released: 32.4 g ( 1 mol / 18.02 g ) (40.67 kJ / mol) = 73.12 kJ

Therefore, 73.12 kJ of heat is released from the condensation of 32.4 g of water vapor.

Write the correct term: In gaseous substances, the individual molecules are relatively (close/far apart) and are moving freely,

GuDViN [60]

Answer:

far apart

Explanation:

The molecules of any gaseous compounds are loosely bound and the molecules are far apart from each other. They move freely and rapidly. The inter-molecular forces are lower as compared to a solid or a liquid where the molecules are comparatively closely bound in the compounds.

Because of the large gap or distance between its molecules, gaseous compounds have less density when compared to any solid or liquid.

Write equations to show whether the solubility of either of the following is affected by pH:(a) CuBr;

V125BC [204]

Increasing pH will increase the solubility of the CuBr.

What is the solubility of water?

When a solute is dissolved in a solvent to give a homogeneous mixture, one has a solution.
Solubility is generally expressed as the number of grams of solute in one liter of saturated solution.
For example, solubility in water might be reported as 12 g/L at 25 oC.

2CuBr + 2OH- ---> Cu2O(s) + 2HBr(aq)

adding OH- to the CuBr also shifts the equilibrium to the right side therefore increasing pH will increase the solubility of the CuBr.

6. Explain the impact on fresh water of:

Paraphin [41]

Fresh water pollutants are substances which pollute fresh water and industrial waste, is most harmful fresh water pollutant to man and aquatic organisms.

<h3>What are pollutants?</h3>

Pollutants are substances which cause harm when they are present in the environment.

Pollutants include chemicals such as petroleum and material such as sewage.

The presence of pollutants in freshwater results in water pollution and make the water unfit for drinking purposes and also harms aquatic life in freshwaters.

Some freshwater pollutants include:

Farming wastes
Household pollutants
Industrial wastes
Erosion
Oil and Gasoline
heat

Of these pollutants, the most dangerous fresh water pollutant is industrial wastes as they kill aquatic organisms most due to the presence of harmful chemicals in them.

Therefore, fresh water pollutants such as industrial waste is most harmful to man and aquatic organisms.
