Question

A chemical equation is balanced when the number of the different atoms of elements

1) in the reactants side is equal to that of the products side.
2) in the reactants side is less than that of the products side.
3) in the reactants side is more than that of the products side.
4) in the reactants side is greater​

Answer 1

In order to satisfy law of conservation or mass which states that total mass of products = total mass of reactants which can be made possible only when no. of atoms of elements used in reactant side is equal to no. of atoms in product side in a balanced chemical reaction.

So, The correct answer is:

$\large{ \blue{ \underline{ \underline{ \bf{Option \: A}}}}}$

A chemical reaction is balanced when the number of the different atoms of elements In the reactant side is equal to that of product side⬆️.

While writing any chemical reaction, we should always write it in balanced form in order to satisfy the law of conservation of mass. A chemical reaction is written using symbols and formulas. The reactions are of two types:

• Unbalanced reaction- It is also known as Skeletal equation where no. of atoms are different in both sides which doesn't satisfy the above law.
• Balanced reaction- It has equal number of atoms in both reactant and product side. Here, along with mass, the note electrical charges are also conserved.

⏏ Do you know? Why there is an integer preceding the compund sometimes? It is used to balance the chemical equation and known as Stoichiometric coefficient. When, there is no such coefficient, we assume it as ① one. Hence, a integer is used. Sometimes, fraction is used but we simplify my multiplying a constant to the entire equation.

Answer 2

Answer:

1) in the reactants side is equal to that of the products side.

Explanation:

In a chemical equation,  two sides of equation HAS to be equal in order to satisfy the equation
