Answer 3

I apologize, but both of the chemical equations you provided are incomplete. They require additional information to balance the chemical equations correctly.

In the first equation, CrO3 + H2O, it is unclear what products are formed, which are necessary to balance the equation.

In the second equation, CaO + HNO, the equation is missing the subscript for the hydrogen, which should be HNO3. Additionally, it is unclear what products are formed, which are necessary to balance the equation.

Please provide the complete equations or additional information so that I can assist you in balancing them correctly.
