To determine the products in the given chemical reaction:
[tex]\[
Zn (s) + 2 HCl (aq) \rightarrow ZnCl_2 (aq) + H_2 (g)
\][/tex]
Let's analyze the equation and identify the substances on both sides of the arrow:
1. Reactants: These are the chemicals present before the reaction takes place, located on the left side of the arrow:
- [tex]\( Zn (s) \)[/tex]
- [tex]\( 2 HCl (aq) \)[/tex]
2. Products: These are the chemicals formed as a result of the reaction, located on the right side of the arrow:
- [tex]\( ZnCl_2 (aq) \)[/tex]
- [tex]\( H_2 (g) \)[/tex]
We can match these substances with the given options:
A. [tex]\( ZnCl_2 (aq) + H_2 (g) \)[/tex] - This matches the products we identified.
B. [tex]\( Zn (s) \)[/tex] - This is a reactant, not a product.
C. [tex]\( Zn (s) + 2 HCl (aq) \)[/tex] - These are reactants, not products.
D. [tex]\( H_2 (g) \)[/tex] - This is only one of the products, the complete list of products includes both [tex]\( H_2 (g) \)[/tex] and [tex]\( ZnCl_2 (aq) \)[/tex].
Therefore, the correct answer is:
A. [tex]\( ZnCl_2 (aq) + H_2 (g) \)[/tex]
So, the product(s) in the reaction are [tex]\( ZnCl_2 (aq) \)[/tex] and [tex]\( H_2 (g) \)[/tex].
