Question

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation:

(
)Zn + (
)HCl → (
)ZnCl2 + (
)H2

Answer 1

Given equation

`\\ \sf\longmapsto Zn+HCl\longrightarrow ZnCl_2+H_2`

Balanced equation

`\\ \sf\longmapsto Zn+2HCl=ZnCl_2+H_2`

Reactant side:-

• Zn=1
• Cl=2
• H=2

Product side:-

• Zn=1
• Cl=2
• H=2

Hence balanced

Answer 2

1 2 1 1
