What does balanced equation mean?
A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.
What is balanced chemical equation explain with example?
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. Also Known As: Balancing the equation, balancing the reaction, conservation of charge and mass.
What is balanced chemical equation class 10?
Balanced Chemical Equation: A balanced chemical equation has number atoms of each element equal on both left and right sides of the reaction. To obey this law, the total mass of elements present in reactants must be equal to the total mass of elements present in products.
What does it mean to say an equation is balanced why is it important for an equation to be balanced?
An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
Why are chemical equations balanced?
1. An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.

What is the chemical reaction and equation?
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What are the 5 types of chemical equations?
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.
What are the rules for writing chemical equations?
Writing Chemical EquationsIn a chemical equation, the reactants are written on the left, and the products are written on the right.The coefficients next to the symbols of entities indicate the number of moles of a substance produced or used in the chemical reaction.
