Choose the correct equation to represent the following statement (unbalanced chemical equation):
aluminum reacts with hydrochloric acid to yield aluminum chloride and hydrogen.
a. alcl3 + h2 al + hcl
b. al + hcl alcl3 + h2
c. al hcl + alcl3 + h2
d. al + hcl alcl3 + h2o

Option (B) is the correct answer.

Explanation:

When aluminium reacts with hydrochloric acid then it results in the formation of aluminium chloride along with emission of hydrogen gas.

The chemical reaction equation for this reaction will be as follows.

It is a single displacement reaction as hydrogen of HCl is displaced by aluminium metal.

Thus, we can conclude that the correct equation to represent the following statement (unbalanced chemical equation) is
