EVERYDAY SCIENCE

Detailed explanation-1: -Chemical equations are written with the reactants on the left side of the equation (reaction arrow) and products on the right side of the equation (reaction arrow).

Detailed explanation-2: -The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction.

Detailed explanation-3: -The reactants are shown on the left and the products are shown on the right. For example: hydrogen and oxygen can react to form water as shown in the equation below. 2H2 + O2 → 2H2O (You can disregard the numbers in the equations during this activity.)

Detailed explanation-4: -In a chemical equation, the products are written on the left-hand side and the reactants on the right-hand side with an arrow in between.

Detailed explanation-5: -Synthesis reactions occur when two or more reactants combine in order to form a singular product. In this case, the 4 hydrogen atoms in the 2 hydrogen gas molecules (H2 ) combine with the 2 oxygen atoms in the 1 molecule of oxygen gas (O2 ). In doing this, only one product, water or H2O H 2 O, is formed.
