Abalanced chemical equation shows the proportions of reactants and products necessary for a. the reaction to occur. c. energy use to be minimized. b. mass to be conserved. d. electrolysis to occur.

Option (b) is the correct answer.

Explanation:

A balanced equation is defined as the equation where number of atoms of the reactant equal to the number of atoms of the product.

This also means that mass of the reactants is equal to the mass of products in a chemical equation.

For example,

Total mass of reactants =

                                      = 116 g/mol

Total mass of products = g/mol

                                      =  116 g/mol

Hence, mass if conserved in a chemical reaction.

thus, we can conclude that a balanced chemical equation shows the proportions of reactants and products necessary for mass to be conserved.

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
