How many atoms are present in a molecule of ?
The correct answer is (b) 5
Explanation:
· A molecule of calcium hydroxide is written as Ca(OH)₂.
· Calcium (Ca): 1 atom.
· Oxygen (O): The subscript "2" outside the bracket multiplies oxygen → 2 atoms.
· Hydrogen (H): The same subscript "2" multiplies hydrogen → 2 atoms.
· Total atoms = 1 + 2 + 2 = 5 atoms.
Information Booster:
· Calcium hydroxide is commonly known as slaked lime.
· It is widely used in neutralizing acidic soils, whitewashing, and water treatment.
