Humans constantly draw on the reserves of these substances while the formation of new supplies takes eons. Renewable resources are the opposite: Their supply replenishes naturally or can be sustained.

Given data:
Number of moles of water produced = ?
Moles of hydrogen react = 8 mol
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Now we will compare the moles of hydrogen and water.
H₂ : H₂O
2 : 2
8 : 8
Thus, 8 moles of water will produced.
There is no need to do anything about the temperature, because sublimation does not involve any temperature change.
First, determine how many moles of CO2 there are. The mol. wt. of CO2 is 12 +2 x 16 = 44 g/mol.
So, 25.0 equals 25/44 = 0.568 moles
So the heat required is 0.568 mol x 32.3 KJ/mol = 18.3
