The standard heat of combustion is shown in the following chemical equation CgH 20 (g) + 140 2(g) 9CO 2(g) + 10H 2 o (1) delta

The given question is incomplete. The complete question is:

The standard heat of combustion is shown in the following chemical equation .  If 130 g of nonane combusts , how much heat is released?

6211.21 kJ

Explanation:

Heat of combustion is the amount of heat released on complete combustion of 1 mole of substance.

Given :

Amount of heat released on combustion of 1 mole of nonane = 6125.21 kJ

According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number of particles.

1 mole of nonane weighs = 128.2 g  

Thus we can say:  

128.2 g of nonane on combustion releases = 6125.21 kJ

Thus 130 g of on combustion releases =

Thus the heat of combustion of 130 g of nonane is 6211.21 kJ

the answer to this question is 3.
