Question

Ca+HNO3->Ca(NO3)2+H2

Answer 1

4Ca + 10HNO3(разб.) = 4Ca(NO3)2 + N2O↑ + 5H2O

Answer 2

Balancing the Chemical Equation: Ca + HNO3 -> Ca(NO3)2 + H2

To balance the chemical equation Ca + HNO3 -> Ca(NO3)2 + H2, we need to ensure that the same number of each type of atom is present on both sides of the equation.

The balanced chemical equation for the reaction is: Ca + 2HNO3 -> Ca(NO3)2 + H2

This balanced equation ensures that the law of conservation of mass is obeyed, with the same number of each type of atom on both sides of the equation.
