Question
Chloroethene, C2H3Cl, reacts with oxygen according to the equation below.2C2H3Cl(g)+5O2(g)→4CO2(g)+2H2O(g)+2HCl(g)What is the amount, in mol, of H2O produced when 10.0 mol of C2H3Cl and 10.0 mol of O2 are mixed together, and the above reaction goes to completion?
Solution
To solve this problem, we need to determine the limiting reactant first, because it determines the maximum amount of product that can be formed.
From the balanced chemical equation, we can see that 2 moles of C2H3Cl react with 5 moles of O2 to produce 2 moles of H2O.
If we have 10.0 moles of C2H3Cl, theoretically we would need 5/2 * 10.0 = 25.0 moles of O2 for the reaction to go to completion. But we only have 10.0 moles of O2, so O2 is the limiting reactant.
Since 5 moles of O2 produce 2 moles of H2O, then 10.0 moles of O2 will produce 2/5 * 10.0 = 4.0 moles of H2O.
So, the amount of H2O produced when 10.0 mol of C2H3Cl and 10.0 mol of O2 are mixed together is 4.0 mol.
