Interpretation:
The chemical equations and mathematical equations needs to be compared.
Concept introduction:
Chemical equation is the symbolic description of a

Answer to Problem 135A
Mathematical equations have no direction but chemical equations have direction. Mathematical and chemical equations are quantitative equations and both are balanced equations.
Explanation of Solution
Mathematical and chemical equations are quantitative equations and both are balanced equations. In terms of mass and atoms chemical equations can be balanced.
Mathematical equations have no direction but chemical equations have direction. It is symbolically described with an arrow which going form reactants to products. Chemical equations have different types of compounds, elements or coefficients etc. But in case of mathematical equations it uses solutions of possible units and numbers.
The examples of mathematical equations and chemical equations are as follows:
