One term in a balanced chemical equation contained the coefficient 2 in front of the formula Ni(OH)2. How many atoms of each type of element does this represent?
The formula Ni(OH)2 consists of one nickel atom (Ni), two oxygen atoms (O), and two hydrogen atoms (H).
Since the coefficient in front of the formula Ni(OH)2 is 2, it means that there are two moles of Ni(OH)2.
Therefore, in 2 moles of Ni(OH)2, there would be:
- 2 moles of Ni atoms (2 x 1 = 2 Ni atoms)
- 4 moles of O atoms (2 x 2 = 4 O atoms)
- 4 moles of H atoms (2 x 2 = 4 H atoms)
So, the coefficient 2 in front of the formula Ni(OH)2 represents 2 Ni atoms, 4 O atoms, and 4 H atoms.
