Answer 1CH4
the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
What are the conventional formulae?
A chemical equation is an expression in which symbols and formulae represent a chemical reaction. It shows the reactants on the left side and the products on the right side, with coefficients to balance the number of atoms on each side.
H is the symbol for hydrogen. The first of the elements.

There are thousands of mathematical formulae.
2(l*w)+2(l*h)+2(w*h) * * * * * That is only true for a cuboid. Other bodies also have surface areas and there are lots of formulae dealing with them.
The chemical formula for an atom is determined by the number of protons in its nucleus, which is unique to each element. For example, the chemical formula for a hydrogen atom is H, for a carbon atom is C, and for an oxygen atom is O.
