=Ca(OH)2 + H,

Hey there!

Assuming you want this equation balanced:

Ca + H₂O → Ca(OH)₂ + H₂

Balance hydrogen.

2 on the left, 4 on the right. Add a coefficient of 2 in front of H₂O.

Ca + 2H₂O → Ca(OH)₂ + H₂

Balance oxygen.

2 on the left, 2 on the right. Already balanced.

Balance calcium.

1 on the left, 1 on the right. Already balanced.

Our final balanced equation:

Ca + 2H₂O → Ca(OH)₂ + H₂

Hope this helps!

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
