Question

Which condition must be met in order for an equation to be balanced? The elements in the reactants are the same as the elements in the products. There are fewer elements in the reactants than there are in the products. The number of atoms in the reactants is greater than the number of atoms in the products. The number of atoms in the reactants equals the number of atoms in the products.

Answer 1

Answer D: The number of atoms in the reactants equals the number of atoms in the products.

Step-by-step explanation:

Had the answer plus doing the quiz right now and got it right 100%

Answer 2

The number of atoms in the reactants equals the number of atoms in the products.

Step-by-step explanation:

In every chemical reaction equation there are two sides; the reactants sides and the products side. The reactants side shows the species that combine to form the products. On both sides of the reaction equation, chemical species are found to be composed of atoms.

The major principle in balancing of chemical reaction equations is that the number of atoms of each element in the reactants side must be equal to the number of atoms of the same element on the products side. Once this condition is achieved, we can now say that the chemical equation is balanced.
