Question

Beofre a chemical equation can be written, one must know

a. the atomic mass of all the elements involved
b. the molar mass of all the compounds
c. the symbols and formulas of all the reactants and products
d. the number of moles of all reactants and products

Answer 1

Before writing a chemical equation, it is important to know the chemical symbols, formulas, and how to balance the equation.

Step-by-step explanation:

In order to write a chemical equation, there are several important things to consider:

1. One must know the chemical symbols for the elements involved in the reaction.
2. One must be able to write the chemical formulas for the different reactants and products.
3. One must also know how to balance the equation by adding coefficients to reflect the ratio of species on both sides of the equation.

To make sure the equation is balanced, the number of atoms of each element in the reactants must be the same as the number of atoms of those same elements in the products. The state of the compounds involved can also be indicated using symbols such as (g) for gas, (l) for liquid, (s) for solid, and (aq) for aqueous solutions.
