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,
[tex]X+Y\rightarrow XY[/tex]
The balanced combination reaction will be,
[tex]Ba(s)+2H_2O(l)\rightarrow Ba(OH)_2(aq)+H_2(g)[/tex]
In this reaction, there are two reactants which are barium (Ba) and water [tex](H_2O)[/tex] react to form [tex]Ba(OH)_2[/tex] and [tex]H_2[/tex] as a product.
Hence, the other reactant is, Barium (Ba)
