Question

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

Answer 1

B. Al+HCl--> AlCl3+H2

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step 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.

`Al + HCl \rightarrow AlCl_(3) + H_(2)`

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
`Al + HCl \rightarrow AlCl_(3) + H_(2)`
