Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake? A. Warm water has a greater heat of vapo
Naya [18.7K]

Answer : The correct option is B.

Explanation :

The temperature of the warm water is higher than the cold water. That means as the temperature of warm water increases, the kinetic energy of the warm water molecule also increases.

As the kinetic energy of the warm water molecule increases, the number of molecules conversion into a vapor also increases (i.e, quick evaporation), thereby increasing the vapor pressure of warm water.

Hence, the correct answer is, (B) Warm water evaporates more quickly.

How many grams of hcl can be produced from the reaction of 23 moles of h2 and 875g of cl2?
max2010maxim [7]

Answer: 899 g

Explanation:

Since the mass of a mole of diatomic chlorine is about 70.9 g/mol, this means that 875 grams is about 875/70.9 = 12.3 mol.

Hence, we know that chlorine is the limiting reactant, and that about 12.3 moles of chlorine will be consumed.

This means that 12.3(2)=24.6 grams of HCl will be produced, which will have a mass of about (24.6)(36.46)=899 g
