Question

CaCO3+HNO3 gives CaNO3+H2O+CO2 balance this equation​

Answer 1

Explanation:

CaCO3 + HNO3 ____ Ca(NO3)2 +H2O +CO2

Answer 2

Answer:

$CaCO_{3} + 2HNO_{3} = Ca(NO_{3} )_{2} + H_{2} O + CO_{2}$

Explanation:

After the = symbol, there are 2 molecules of H whereas, before the equation, there is only 1 molecule of H. So, in order to balance the equation, we have 2 compounds of nitric acid before the =. So after the =, there are 2 NO3.
