Question

Waht is balance chemical equation why solution of chemical equations be balanced

Answer 1

Explanation:

A chemical equation in which the total number of atoms in reactants and total number of atoms in product are equal is known as balanced chemical equation.

For example-:

normal equation,

Mg + O2 ------> MgO

balanced equation,

2Mg + O2 --------> 2MgO

in the above example we can see that the atoms of Mg (Magnesium) and O (Oxygen) are equal in both sides.

Chemical equation should be balanced to satisfy the law of conservation of mass which states that the mass of products in a chemical equation must equals the mass of reactants.

Answer 2

$\huge\bold{\mathtt{\purple{♡A{\pink{N{\green{S{\blue{W{\red{E{\orange{R}}}}}}}}}}}}}$

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.

$\huge\underline\mathfrak\green{Reason \: for \: balancing }$

Law of conservation of mass governs the balancing of a chemical equation. According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side. If the chemical equation is not balanced law of conservation is not applicable.
