Question

Which of the following statements is not true about balanced chemical equations?
a. Reactants and products are given in the chemical reaction.
b. The number of atoms of each element remains the same before and after a chemical reaction.
c. The mass of each element is not the same before and after a chemical reaction.
d. The reaction conditions are indicated above or below the arrow in the equations.​

Answer 1

'(b) The number of atoms of each element remains the same before and after a chemical reaction' is an incorrect statement. It is not necessarily the same in both sides of the reaction.

Answer 2

A balanced chemical reaction does not have the same number of atoms in each element before and after the reaction.

Explanation:

• An adjusted chemical response implies that the number of iotas of each component is rise to on both sides.
• A balanced chemical reaction is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge, same for both the reactants and the products.
• If each side of the equation has the same number of atoms of a given element that is balanced is called a balanced chemical reaction.
