Chapter 9, Problem 57A

Interpretation Introduction

Interpretation:

A chemical equation needs to be explained.

Concept introduction:

With the help of chemical equation chemical reaction can be expressed by paper. Example:

${\text{CH}}_{\text{4}}\text{+}{\text{2O}}_{\text{2}}\to {\text{CO}}_{\text{2}}{\text{+2H}}_{\text{2}}\text{O}$

Answer to Problem 57A

The symbolic description of a chemical reaction that products and reactants are indicating in terms of their chemical formula is chemical equation.

Explanation of Solution

The symbolic description of a chemical reaction that products and reactants are indicating in terms of their chemical formula is chemical equation. To indicate the physical states of the substrates chemical equation utilizes symbols, chemical formulas to indicate substrates involve and to indicate direction of reaction arrow is used. In a chemical reaction how many atoms are involve in the reaction is indicate by placing whole number coefficients in front of each substrate.

Conclusion

In a chemical equation arrow is used to indicate direction of reaction. By placing whole number coefficients in front of each substrate indicated how many atoms are involve in the chemical reaction.
