consider the following reaction:
2C2H6(g)+7O2 (g)-->4CO2(g)+6H2O (g)
delta H = -3120kJ
If 3.00g of ethane are burned, how many kJ of heat are produced?

• chemistry -

It says for each two moles, you get 3120kj of heat. Do it as a fraction, 3/(2molmass) * 3120 kg

• chemistry -

12

• chemistry -

-3821kJ/mol
