1)how many molecules of water are needed to produce 6 molecules of C6H12O6 according to the equation 6CO2(G)+6H2O(L)+energy TO C6H12O6(S)+6O2(G)?
2)how many mole of oxygen gas are produce when 6 mol of CO2 are consumed in the process of photosynthesis(see above question for the equation)
3)H2(G)+Cl2(g) to 2HCl(g)if 2 mol of H gas are mixed with 4 mol of Cl gas, how many moles of HCl will be produced?

1. The equation tells you 6 molecules of water are needed to produce 6 molecules of C6H12O6.
2. The equation tells you that 6 moles of O2 are produced for 6 moles CO2 consumed.
3. H2 + Cl2 ==> 2HCl
2 moles H2 gas will react with 2 moles Cl2 gas to produce 4 moles HCl gas. Two moles of the Cl2 gas will go unreacted.
