Question

Balance the towing chemical ecuation-
I HNO 3+ Cao Hoa - Cee (NO3)2 + H2O and explain it​

Answer 1

Answer:

Explanation:

CaO + HNO3 → Ca(NO3)2 + H2O

Word equation: Calcium oxide + Nitric acid → Calcium nitrate + water

Type of Chemical Reaction: For this reaction we have a double replacement reaction.

Balancing Strategies: To balance this equation it is helpful to consider the nitrate ion (NO3) to be one item. That is because it appears on both sides of the equation. This makes the balancing much, much simpler.

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).

Coefficients are the numbers in front of the molecule.

Never change the subscripts (the small numbers after elements).

Coefficients are the numbers in front of the molecule.
