Question

37.
If you had to write a math equation, you probably
wouldn't write, "Twenty-eight plus fourteen equals
forty-two." It would take too long to write and it would
be hard to read quickly.

(A) For example, the chemical formula for water is H2O.
That tells us that a water molecule is made up of two
hydrogen ("H" and "2") atoms and one oxygen ("O")
atom.

(B) You would write, "28 + 14 = 42." Chemistry is the same
way. Chemists have to write chemical equations all the
time, and it would take too long to write and read if
they had to spell everything out.

(C) So chemists use symbols, just like we do in math. A
chemical formula lists all the elements that form each
molecule and uses a small number to the bottom right
of an element's symbol to stand for the number of
atoms of □□□□□. □□□□□. □□□□□.
