Answer 1

Answer: HCI is 2 and ZN is blank and ZnCI2 is blank and H2 is blank

i hope this helps who ever needs it

Answer 2

Answer: Option (a) is the correct answer.

Step-by-step explanation:

The given equation is as follows.

`HCl + Zn \rightarrow ZnCl_(2) + H_(2)`

Number of atoms on reactant side are as follows.

• H = 1
• Cl = 1
• Zn = 1

Number of atoms on product side are as follows.

• H = 2
• Zn = 1
• Cl = 2

To balance the equation, multiply HCl by 2 on reactant side. Therefore, the balanced chemical equation is as follows.

`2HCl + Zn \rightarrow ZnCl_(2) + H_(2)`
