Question

State true or false.
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.
A.True
B.False

Answer 1

Every chemical equation undergoes the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation. Use coefficients of product and reactant to balance the number of atoms of an element on both sides of a chemical equation.

Complete step by step answer:
Chemical equations are representations of chemical reactions in which the reactants and the product are expressed. They use symbols to represent factors such as the direction of the reaction and the physical states of the reactant.
The reactants and the products (for which the chemical formulae are written in chemical equations) can be separated by the following:
In the forward reaction, the symbol $\xrightarrow{{}}$ is used.
To describe a state of chemical equilibrium, the symbol is used.
To the stoichiometric relationships, the $=$ symbol is used.
To describe a reaction that occurs in both forward and backward directions, the symbol $\overset {} \leftrightarrows$ is used.
The left-hand side of a chemical equation represents the reactants and the right-hand side represents the product. These are separated by a symbol that describes the direction of the reaction.
An arrow represents the direction in which the chemical equation flows. The symbol $\xrightarrow{{}}$ is used to represent an arrow and is read as “gives rise” or “yields”.
With this in a chemical equation, the products are written on the left-hand side and the reactants on the right-hand side with an arrow are true.
Thus the correct answer is (A).

Note:
Law of conservation of mass: Matter cannot be created or destroyed. Therefore, in a closed system, the mass of the reactants must equal the mass of the products.
Coefficient: A constant by which an algebraic term is multiplied.
When an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced.
