write the mole ratio for each of the following balanced chemical equations

Question

1) N₂ + 3H₂ —> 2NH₃

2) Zn + 2HCl —> ZnCl₂ + H₂

3) 2Al + 3S —> Al₂ S₃

Answer 1

1) N₂ + 3H₂ —> 2NH₃

N₂/H₂ = 1:3

N₂/NH₃ = 1:2

H₂/NH₃ = 3:2

2) Zn + 2HCl —> ZnCl₂ + H₂

Zn/HCl = 1:2

Zn/ZnCl₂ = 1:1

Zn/H₂ = 1:1

HCl/ZnCl₂ = 2:1

HCl/H₂ = 2:1

3) 2Al + 3S —> Al₂ S₃

Al/S = 2:3

Al/Al₂S₃ = 2:1

S/Al₂S₃ = 3:1
