The molar heat of solution of ammonia is −30.50 kJ/mol. What happens to the temperature of water when ammonia is added to it?

I simply don't know how to answer this and wouldn't ask otherwise. I would be very grateful for assistance.

NH + H2O = NH3(aq) + 30.50 kJ/mol

So this tells you that the solution becomes warmer.

When ammonia is added to water, it undergoes dissolution which is an exothermic process. The negative molar heat of solution (-30.50 kJ/mol) indicates that heat is released when one mole of ammonia dissolves in water.

The release of heat leads to an increase in the temperature of the water. This increase in temperature occurs because the energy released from the dissolution process is transferred to the surrounding water molecules, causing them to move faster and increasing the overall kinetic energy and temperature of the system.

So, when ammonia is added to water, the temperature of the water generally increases.

To determine what happens to the temperature of water when ammonia is added, we can use the concept of heat transfer. When a substance dissolves in water, heat can either be absorbed or released. The molar heat of solution gives us information about the heat exchange that occurs during the dissolution process.

In this case, the molar heat of solution of ammonia is given as -30.50 kJ/mol. The negative sign indicates that heat is released when ammonia dissolves in water, meaning the process is exothermic. This implies that the temperature of water will increase when ammonia is added.

To calculate the temperature change, we can use the equation:

ΔT = q / (m × C)

Where:
- ΔT represents the change in temperature
- q represents the heat released (in this case) or absorbed (if positive) during the process
- m represents the mass of the solvent (water)
- C represents the specific heat capacity of the solvent (water)

Please note that using this equation assumes that the heat is transferred only to the water and not to the surroundings.

To solve the problem, we need to know the masses of both ammonia and water, as well as the specific heat capacity of water. If you have that information, we can proceed with the calculation.
