When the number of atoms of each element is the same on both sides of the equation, it is a/an-

Correct option is A

The correct answer is (a) Balanced equation.
· A balanced equation is a chemical equation where the number of atoms of each element is the same on both sides of the equation, ensuring that the law of conservation of mass is obeyed.
· In a balanced equation, no atoms are lost or gained, meaning the mass of the reactants equals the mass of the products.
· Balancing chemical equations is a fundamental step in understanding chemical reactions and stoichiometry.
Information Booster:
· The process of balancing an equation involves adjusting the coefficients (numbers in front of molecules or atoms) to ensure the same number of atoms for each element on both sides of the equation.
· For example, the balanced equation for the combustion of methane is: CH4+2O2→CO2+2H2OCH4 + 2O2
· Balancing is essential for calculating the amounts of reactants and products in a reaction.
Additional Knowledge:
· Mixed equation: This term is not used in chemistry.
· Skeletal equation: Refers to an unbalanced chemical equation that only shows the formulas of the reactants and products without balancing the atoms.
· Unbalanced equation: An equation where the number of atoms of each element is not equal on both sides.
