The standard enthalpy of formation is the change in enthalpy that accompanies the formation of one mole of the compound from its elements. The standard enthalpy of reaction occurs in a system when one mole of matter is transformed by a chemical reaction.

C6H12O6(s) + 6O2(g) --> 6CO2(g) + 6H2O(g). ∆H=–1273.3 kJ/mol.

Justify - H*(CO2) = Delta_f H*(CO2) [*means zero in superscript and _f means f in subscript] where, H* is standard enthalpy and Delta_f H* means standard enthalpy change of formation.

C + O2 --gt; CO2 Delta_f H*(CO2) = H*(CO2) - [H*(C) + H*(O2)] The standard enthalpy of elementary substance is zero: H*(C) = H*(O2) = 0 Therefore Delta_f H*(CO2) =...

The reaction for producing glucose in plants, called photosynthesis, is 6 CO2 + 6 H2O → (light) C6H12O6 + 6 O2 If a plant produces 2.51 mol C6H12O6, how many moles of H2O are needed?

6 CO2 + 6 H2O → (light) C6H12O6 + 6 O2n(C6H12O6)=2.51 moln(H2O)=6*n(C6H12O6)=6*2.51 mol=15.06 mol

What is the total number of moles of water needed to make 2.5 moles of C6H12O6 ? CO2+H2O=C6H12O6 + O2

6CO2 + 6H2O = C6H12O6 + 6O2n(H2O) = 6 × 2.5 = 15 mol.

C12H22O11 + H2O = C6H12O6 + C6H12O6 If 10 mol of water have been used in the reaction, how many mol of sucrose have been used?

The reaction equation is fully balanced.So the quantity of sucrose is equal to the quantity of water - 10 molAnswer: 10 mol
