In a reaction container 100g of hydrogen
WebExample: 100g of hydrochloric acid is added to 100g of zinc. Find the volume of hydrogen gas evolved under standard laboratory conditions. Solution: The chemical equation for these reactions is given below. 2HCl (aq) + Zn (s) → ZnCl 2 (aq) + H 2 (g) Zinc chloride is formed in excess so the limiting reagent here is hydrochloric acid. WebBelow are two examples of mathematical calculations that could be performed to find the limiting reactant for Container U in Question 13. 2 mol H O 8 mol H 2 (————– 2) = 8 mol H 2 O 2 mol H 2 (2 mol H 2 O) 6 mol O ————– = 12 mol H O 2 1 mol O 2 Hydrogen makes the lesser amount of product, so it is the limiting reactant.
