The balanced chemical equation is to be written that shows the reaction of given metal oxides with HNO 3 . Concept Introduction: Acids are the substances which give hydrogen ( H + ) ions in solution. The reaction between metal oxide (base) and acid is known as neutralization reaction. The reaction in between metal oxide and an acid yields water along with the formation of dissolved salt. For balancing a chemical equation change the coefficient, not subscript as changing subscript change the type of molecule. The steps to balance chemical equation are: If there is an element that is present in just one compound on both sides of the equation, it has to be balanced first. If there are more than one such element is there, balance metals before non-metals. If the element is present in a free state on both the sides of the equation, balance it last. These elements are balanced by adjusting the coefficients. If coefficients are present in a fraction, convert it into whole numbers by multiplying with the appropriate number.

Interpretation Introduction

Interpretation:

The balanced chemical equation is to be written that shows the reaction of given metal oxides with HNO3.

Concept Introduction:

Acids are the substances which give hydrogen (H+) ions in solution.

The reaction between metal oxide (base) and acid is known as neutralization reaction.

The reaction in between metal oxide and an acid yields water along with the formation of dissolved salt.

For balancing a chemical equation change the coefficient, not subscript as changing subscript change the type of molecule.

The steps to balance chemical equation are:

If there is an element that is present in just one compound on both sides of the equation, it has to be balanced first.

If there are more than one such element is there, balance metals before non-metals.

If the element is present in a free state on both the sides of the equation, balance it last. These elements are balanced by adjusting the coefficients.

If coefficients are present in a fraction, convert it into whole numbers by multiplying with the appropriate number.
