Calculate the volume required to prepare 500 mL of 3650 ppm HCl

solution. (Sp. gr. =1.18, % = 36 %).

Equal volumes of h2 and o2 are placed in a balloon and then ignited. assuming that the reaction goes to completion, which gas will remain in excess? 2h2 + o2 → 2h2o a. both are in equal proportion b. oxygen c. water d. hydrogen
