The combustion of 14 grams of co, according to the reaction co(g) + ½o2(g) → co2(g) + 67.6 kcal, gives off how much heat?

The amount of heat released by the combustion of 14 g of CO is 33.8 kCal

Explanation:

To calculate the number of moles, we use the equation:

Given mass of CO = 14 g

Molar mass of CO = 28 g/mol

Putting values in above equation, we get:

The chemical reaction for the combustion of CO follows the equation:

By Stoichiometry of the reaction:

If 1 mole of CO produces 67.6 kCal of heat

Then, 0.5 moles of CO will produce = of heat.

Hence, the amount of heat released by the combustion of 14 g of CO is 33.8 kCal
