How to Make a Pale-Yellow Color by Mixing two Colors

Answer: A chemical equation is a representation of a chemical process in the form of substances. A balanced chemical equation is one in which the number of atoms in all of the molecules is equal on both sides of the equation.

• The balancing of a chemical equation is governed by the Law of Conservation of Mass.
• This law states that in a chemical reaction, mass cannot be generated or destroyed, and that the total mass of the elements or molecules present on the reactant side should match the total mass of elements or molecules present on the product side.
• The law of conservation does not apply if the chemical equation is not balanced.

1. H2g+ Cl2g2HClg

Hydrogen chloride gas is formed when hydrogen gas and chlorine gas mix.

1. 3BaCl2s+ Al2SO43s3BaSO4s + 2AlCl3s

When barium chloride combines with aluminum sulphate, barium sulphate and aluminum chloride are formed.

1. 2Nas+2H2Ol2NaOHaq+H2g

When sodium combines with water, sodium hydroxide and hydrogen gas are formed. A redox reaction is exemplified by this reaction.
