Final answer:
The number of atoms of hydrogen represented in different chemical formulas
Step-by-step explanation:
In the chemical formula below, the number after each element represents the number of atoms of that element. In the given options:
- O6: There are 6 atoms of oxygen.
- O4: There are 4 atoms of oxygen.
- O2: There are 2 atoms of oxygen.
- O8: There are 8 atoms of oxygen.
- 4Ca(OH)2: There are a total of 2 hydrogen atoms per hydroxide group (OH)2, and there are 4 hydroxide groups in the formula. Therefore, there are 4 x 2 = 8 atoms of hydrogen.
Thus, in the chemical formula O6, there are 6 atoms of oxygen; in O4, there are 4 atoms of oxygen; in O2, there are 2 atoms of oxygen; in O8, there are 8 atoms of oxygen; and in 4Ca(OH)2, there are 8 atoms of hydrogen.
