Question

write balanced equation for the following reactions calcium + water ----------> calcium hydroxide + hydrogen

Answer 1

2Ca + 2H2O. --------> 2Ca[OH]2 + H2

Answer 2

Hey !

Calcium + Water ----------> Calcium hydroxide + Hydrogen

Ca + H₂O ---> Ca(OH)₂ + H₂

LHS :-
Ca = 1
H = 2
O = 1

RHS :-
Ca = 1
O = 2
H = 4


Balanced equation :-
Ca + 2H₂O ---> Ca(OH)₂ + H₂

here ,
LHS :-
Ca = 1
H = 4
O = 2

RHS :-
Ca = 1
H = 4
O = 2

Hope this helps you !!
