Chapter 20, Problem 1RQ

Interpretation Introduction

Interpretation:

The fact that makes the given condition possible during the calculation involving chemical reactions, is to be interpreted.

Concept Introduction:

Law of conservation of mass states that the mass of products and reactants always remains constant during a chemical reaction.

Law of conservation of energy is defined as the basic law that energy can never be created and never be destroyed.

The change in mass and energy is given by the equation as follows:

$\Delta \text{E}=\Delta \text{m}\times {\text{c}}^2$, where c is the speed of light in m s^-1.
