Can the subscripts in a chemical formula be fractions? Explain. Can the coefficients in a balanced chemical equation be fractions? Explain. Changing the subscripts of chemicals can balance the equations mathematically. Why is this unacceptable?

Interpretation Introduction

Interpretation: An explanation regarding the stated facts is to be determined.

Concept introduction: A chemical equation in which the number of atoms of the reactant elements is same as the number of atoms of the product elements and the overall charge is same on both sides of the reaction is termed as a balanced chemical equation.

To determine: If the subscripts in a chemical formula can be fractions; if the coefficients in a balanced chemical equation can be fractions; if changing the subscripts of chemicals to balance the equations mathematically is justified.

Explanation

To determine: If the subscripts in a chemical formula can be fractions.

The subscripts present in a chemical formula give the number of atoms of the element present.

The subscript in a chemical formula cannot be represented by a fraction.

To determine: If the coefficients in a balanced chemical equation can be fractions.

The coefficients present in a balanced chemical equation give the number of moles of the reactant present.

The coefficients present in a balanced chemical equation can be represented by a fraction...
