Explain how a correctly written equation shows atoms are not lost in a reaction and this is not for school or class this is a question my friend has been asking me with so people shove off with the class jokes.

number of atoms (of each element) on one side equals the other side.

Ex: 2H2 + O2---> 2H2O
This is called a balanced chemical reaction. The 'balance' comes from the fact that there are the same # of atoms of each kind on both sides; that is, all of the reactants are accounted for in the product of the reaction.
In this example, 2 molecules of hydrogen (4 atoms total) combine with 1 molecule of oxygen (2 atoms total). The 2 preceeding the product means everything is multiplied by 2, so again I have 4 H atoms and 2 O atoms.

Since a correctly written eq
has equal no. of atoms of
each kind on same side
it shows that as much u put
into a reaction equal no. u get out

Just look at a simple balanced equation such as
Fe + S ---> FeS
There are only Fe and S atoms in it, so no elements are gained or lost.
Also, only one atom of each is involved, and no atoms are gained or lost.
