Question

Which of the following statements about balanced chemical equations is true? (Select all that apply)

a. Each specific atom must be balanced on both sides
b. The molecules must be balanced on both sides
c. The mass is conserved according to the Law of Conservation of Mass
d. The net charge must be balanced on both sides

Answer 1

True statements about balanced chemical equations include that each specific atom and the net charge must be balanced on both sides, and the mass is conserved according to the Law of Conservation of Mass.

Step-by-step explanation:

In regards to balanced chemical equations, there are specific criteria that must be met:

• Each specific atom must be balanced on both sides. This ensures that the number of atoms for each element is conserved across the reactants and products.
• The law of conservation of mass dictates that the mass must be conserved in a chemical reaction, which is demonstrated by having an equal number of atoms of each element on both sides of the equation.
• The net charge must also be balanced on both sides, meaning the overall charge should be the same for the reactants and products.

Therefore, the statements that are true for balanced chemical equations include: (a) Each specific atom must be balanced on both sides, (c) The mass is conserved according to the Law of Conservation of Mass, and (d) The net charge must be balanced on both sides.
