Kemmi major does some experimental work on the combustion of sucrose: c12h22o11(s) 12 o2(g) → 12 co2(g) 11 h2o(g) she burns a 0.05392 g pellet of sucrose in a bomb calorimeter with excess oxygen. she determines the qrxn to be –916.6 j for the reaction. calculate the ∆h value for the combustion reaction. (round the answer to 3 significant digits, units of kj, pay attention to positive or negative.

Explanation:

Heat of combustion is the amount of heat released when 1 mole of the compound is completely burnt in the presence of oxygen.

To calculate the moles, we use the equation:

Thus of sucrose releases =  916.6 J of heat

1 mole of sucrose releases = of heat

Thus ∆H value for the combustion reaction is

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
