Question

Determine the energy release when 13.2g of O2 was reacted with sugar C12H22O11 + 12 O2 → 12 CO2 + 11 H2O + 5638 kJ

Answer 1

The energy release when 13.2g of O2 reacted with sugar C12H22O11 is 5638 kJ. This can be determined using the balanced thermochemical equation and stoichiometry.

Step-by-step explanation:

The energy release when 13.2g of O2 reacted with sugar C12H22O11 is 5638 kJ.

This can be determined using the balanced thermochemical equation: C12H22O11 + 12 O2 → 12 CO2 + 11 H2O + 5638 kJ. From the equation, we can see that 1 mole of O2 releases 5638 kJ of energy. The molar mass of O2 is 32 g/mol. Therefore, to find the energy release for 13.2g of O2, we can use the molar mass and stoichiometry:

(13.2g O2 / 32g/mol) x (5638 kJ / 1 mol) = 2319.75 kJ
