Assuming complete combustion of sucrose, the products formed will be carbon dioxide and water. You can follow their steps in the video explanation above. 1 mole of sucrose reacts with 12 moles of oxygen gas to give 12 moles of {eq}CO_{2} Answer to: Write and balance the chemical equation upon the combustion of sucrose. the law of conservation of energy states that energy cannot be created nor destroyed. you measure the amount and determine that there are 5 grams of potassium-40 in the rock.

The combustion of sucrose in an atmosphere of pure oxygen proceeds by the following equation: C 12 H 22 O 11 (s) + 12 O 2 (g) -----> 12 CO 2 (g) + 11 H 2 O(l) If the standard enthalpy change for this reaction can be measured, and if we can look up the values of H f o for three of the four chemicals in the equation, then we can use the Hess law equation to find the H f o of the remaining substance, sucrose.
