Even if you used the right specific heat (c) and temperature change (∆T) for ice, for liquid, and for steam, it does not give you the total amount of energy required for this problem. What is still missing, and explain why that requires energy!

Heat of melting s = 333 kJ/kg and heat of vaporisation r= 2160 kJ/kg

Explanation:

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
