Detailed explanation-1: -When sugar is burned, water vapor and carbon dioxide are produced. A sugar molecule has a specific number of carbon, hydrogen, and oxygen atoms. Use the balanced chemical equation to identify the number of carbon, hydrogen, and oxygen atoms in sugar. sugar + 12O2 → 11H2O + 12CO2 Sugar has 1112222435 carbon atoms.
Detailed explanation-2: -If sugar burns completely (complete combustion) then the products of the reaction are carbon dioxide and water.
Detailed explanation-3: -If common sugars are heated too strongly, they char as they decompose into carbon and water vapor. For example, if sucrose (table sugar) is heated, the reaction is C12H22O11(s)→12C(s)+11H2O(g) C 12 H 22 O 11 ( s ) → 12 C ( s ) + 11 H 2 O ( g ) .
Detailed explanation-4: -Q. Acetylene [C2H2] burns in air forming carbon dioxide and water vapour.
