Respuesta :

it is balanced so the coefficient would be 1 and it seems to be dehydration synthesis?
To figure if this equation is balanced or not, we must determine if the reactants are the same as the products.

Ca=1                     Ca=1
C=1                       C=1
O=3                       O=2+1=3
H=2                       H=2
Cl=2                      Cl=2

Since the amount of each element on the reactants side is equivalent to what is on the products side, we have a balanced equation. 

Final answer: This equation is balanced.
