Question

The product of a combination reaction is ba(oh)2 if one of the reactants is h2) what is the other reactant

Answer 1

Answer : The other reactant is, Barium (Ba)

Explanation :

Combination reaction : A chemical reaction in which two or more reactants combine to form new products.

It is represented as,

`X+Y\rightarrow XY`

The balanced combination reaction will be,

`Ba(s)+2H_2O(l)\rightarrow Ba(OH)_2(aq)+H_2(g)`

In this reaction, there are two reactants which are barium (Ba) and water
`(H_2O)` react to form
`Ba(OH)_2` and
`H_2` as a product.

Hence, the other reactant is, Barium (Ba)
