Question

Which statement best describes the equation caco3 2hcl → cacl2 co2 h2o?

Answer 1

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.

Answer 2

it is balanced so the coefficient would be 1 and it seems to be dehydration synthesis?
