Question

Turn the following word equation into a symbolic equation: aluminum reacts with hydrochloric acid to form aluminum chloride and hydrogen.

Answer 1

Based on the given option, the unbalanced form is Option A

Explanations:

Equation is known to be balanced when the number of moles of element at the reactant is equal to that of product.

Aluminum = Al

Hydrochloric acid = HCl

The reaction formed by Aluminum and hydrochloric acid is expressed as:

`Al+HCl\rightarrow AlCl_3+H_2`

The balanced form of the reaction will be expressed as:

`2Al+6HCl\rightarrow2AlCl_3+3H_2`
