Answer to Question #279355 in General Chemistry for jhon

Question

A company uses H2 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/cm3

and they took a 0.875 cm3

small piece of alloy to react with 200 mL of 1.2 M solution

of HCl 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 H2 gas that they obtained?

Answer 1

2 Al (s) + 6 HCl (aq) → 2 AlCl3 (aq) + 3 H2 (g)

The limiting reactant is Al
