right answer plz​

Answer 1

Answer:

the total number of atoms on the LHS of the reaction should be equal to that on the RHS of the reaction

a Chemical equation is a method to represent a chemical reaction

Please mark me brainliest

Answer 2

Answer:

the total number of atoms on the LHS of the reaction should be BALANCED to that on the RHS of the reaction..

a LAW OF CONSERVATION OF MATTER is a method to represent a chemical reaction

Step-by-step explanation:

When the number of atoms of each element of the reactant/reactants is equal to the number of atoms of the elements of the product/products is same, then the equation is said to be balanced.

For example: 2Mg\ +\ O_22Mg + O  

2

​

 → 2MgO2MgO

Reactants = 2 atoms of magnesium and 2 atoms of oxygen

Product = 2 Magnesium Oxide

Reasons for balancing chemical equation:

Law of conservation of matter states that matter is neither created nor destroyed during a chemical reaction.

It is true only if the number of atoms on both sides is equal, because otherwise there will be addition or subtraction of atoms.
