Question

Which of the following is true for balancing equations? The number of products should be equal to the number of reactants. The properties of products should be the same as the properties of reactants. There must be as equal number of compounds on both sides of the equation. There must be as equal number of atoms of each element on both sides of the equation.

Answer 1

Hello!

The right answer is There must be an equal number of atoms of each element on both sides of the equation.

Balancing Equations is a part of Stoichiometry. The Balancing of Equations is based on the Law of Conservation of Matter, which states that the matter is neither created nor destroyed and in a chemical reaction only changes in the matter occurs. For this law to be obeyed, there must be an equal number of atoms of each element on both sides of the equation.

Have a nice day!

Answer 2
