Answer:
- There are 3 hydrogen atoms in the representative particle of Al(OH)₃
Step-by-step explanation:
- Al(OH)₃ is the chemical formula for the representative particle of aluminum hydroxide.
- Since Al (aluminum) has not any subscript associated, it is understood that there is 1 atom of aluminum in each representative particle of Al(OH)₃.
- Since the subscript 3 is after a parenthesis, it affects all the atoms that are inside such parenthesis. This leads to:
- there are 3 atoms of oxygen in each representative particle of Al(OH)₃, and
- there are 3 atoms of hydrogen in each representative particle of Al(OH)₃.
