SSC MTS EXAM

Detailed explanation-1: -The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted.

Detailed explanation-2: -The law of conservation of mass states that matter cannot be created nor destroyed, only it’s form changed. Take the example of burning a piece of paper. It seems that the mass shrinks as the paper burns. However, what is really happening is that the paper is changing form to ash, carbon dioxide, and water vapor.

Detailed explanation-3: -The law of conservation of mass states that no atoms are lost or made in a chemical reaction. Instead, the atoms join together in different ways to form products . This is why, in a balanced symbol equation, the number of atoms of each element is the same on both sides of the equation.
