This chemical formula is Pb(OH)2.
This is the chemical formula for strontium hydroxide.
The ion hydroxyl is -OH.
A person would have to see what the equations are to know which represents the lead at a high rate. Of this is provided the answer can be known.
Calcium hydroxide formula is 'Ca(OH)2' Note the use of brackets, which indicate that there are two hydroxide anions in the formula. NNB CaOH2 is incorrect, because this indicates only two hydrogen atoms and one oxygen atom .

Formula: PbO
Formula: PbS
This chemical formula is Pb3P2.
A general formula is MeOH (Me is a metal).
PbBr2
It would be: PbI2
