Question

A company uses Ha gas to generate electricity. They studied a smaller scale model reaction

to figure out the maximum amount of H2 gas that they can produce. For this purpose, they

used an alloy consisting of 95% Al by mass. The alloy has a density of 3.12 g/cm" and they

took a 0.875 cm? small piece of alloy to react with 200 mL of 1.2 M solution of HCI based on

the given Al specific reaction. What is the maximum amount of H2 gas that can be produced?

What are the limiting and remaining reagents? How can they increase the amount of Ha gas

that they obtained?

AI + HCI > AICIz + H2 (not balanced)

Answer 1

Amount of H2 gas=11.3g
