How do you identify the chemical formula?

Explanation:

A chemical formula represents the atoms and the ratios by which they combine together in a compound or molecule.

So, in order to identify a chemical formula;

The valency is a good indicator of the combining power of every atom in forming a compound.

Most often times,

   NaOH is the symbol of sodium hydroxide containing :

                       Na       Sodium

                        O          Oxygen

                        H           Hydrogen

Several other compounds have formula more complicated or less complicated than this.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
