Green plants use light from the Sun to drive photosynthesis, a chemical reaction in which liquid water and carbon dioxide gas form aqueous glucose C6H12O6 and oxygen O2 gas. Calculate the moles of water needed to produce 0.075mol of glucose. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits

0.45 moles of water are needed to produce 0.075mol of glucose.

Explanation:

The balanced chemical reaction is:

According to stoichiometry :

1 mole of glucose require = 6 moles of

Thus 0.075 moles of glucose require = moles of

0.45 moles of water are needed to produce 0.075mol of glucose.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
