Write the chemical equation for the reaction whose enthalpy change is the standard enthalpy of formation of sucrose, C12H22O11(s), HfHf[{
m C_{12}H_{22}O_{11}}].

We’re being asked to determine the balanced chemical equation for the reaction used to calculate the standard enthalpy of formation of sucrose C12H22O11.Recall that the standard enthalpy of formation (ΔH°f) refers to the enthalpy change for the formation of 1 mole of a compound from its elements in their standard states.[readmore]This means for C12H22O11, the reaction involves the formation of 1 mole of C12H22O11 from C, H, and O in their standard states. In their standard states, carbon C exists as a solid C(s), while both H and O exist as a diatomic gas, H2(g) and O2(g).The unbalanced reaction is:C(s) + H2(g) + O2(g) → C12H22O11(s)Balancing the chemical reaction for 1 mole of sucrose: 1. Balance the non-oxygen and non-hydrogen elements first: C12 C(s) + H2(g) + O2(g) → C12H22O11(s)(C: balance by adding a coefficient of 12 in C(s))2. Balance Hydrogen12 C(s) + 11 H2(g) + O2(g) → C12H22O11(s)(H: balance by adding a coefficient of 11 in H2(g))3. Balance Oxygen12 C(s) + 11 H2(g) + 11/2 O2(g) → C12H22O11(s)(O: balanced by adding a coefficient of 11/2 in O2)The balanced chemical equation for the formation of sucrose C12H22O11(s) is:12 C(s) + 11 H2(g) + 11/2 O2(g) → C12H22O11(s)
