Calculate the energy in the form of heat (in kJ) required to convert 225 grams of liquid water at 21.0C to steam at 115C (Heat of fusion=333 J/g heat of vaporization=2256 J/g: specific heat capacities liquid = 4.184 J/gC steam = 1.92 J/g. K

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.
