13. base your answer to the following question on the information below and you knowledge of chemistry,
a 100.-gram sample of liquid water is heated from 20.0°c to 50.0°c. enough kcion(s) is dissolved
in the sample of water at 50.0°c to form a saturated solution.
using the information on table b, determine the amount of heat absorbed by the water
when the water is heated from 20.0°c to 50.0°c.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
