Question

2h2( 4gm)+ o2( 32gm) = 2h2o(36gm) mass of water formed when 2gm of hydrogen reacts is...​

Answer 1

Answer:

2H

2

+O

2

→2H

2

O

Molecular mass of H

2

=2 g/mol

Molecular mass of O

2

=32 g/mol

From the balanced chemical equation,

2×2=4 g of hydrogen requires 32 g of Oxygen to react completely
