Which reaction type is 2Na + 2H₂O → 2NaOH + H₂? MCQ with Answer and Explanation

Which reaction type is 2Na + 2H₂O → 2NaOH + H₂?
A. Double displacement
B. Decomposition
C. Combination
D. Displacement
Answer: Option D
Solution (By JKExamLibrary)
Sodium displaces hydrogen from water, a single displacement reaction. It is also a redox reaction (Na oxidized, H⁺ reduced). Not combination (one product), not decomposition (one reactant), not double displacement.

Question #2
The micelle formation by soap in water is possible due to:
A. Hydrophilic head and hydrophobic tail
B. Electrostatic repulsion
C. Only hydrophobic interaction
D. Covalent bonding with dirt

Correct Answer: Option A


Explanation:
Soap molecules have a hydrophilic ionic head (COO⁻Na⁺) and a long hydrophobic hydrocarbon tail. In water, the tails aggregate away from water, forming a spherical micelle with heads outward. The hydrophobic core dissolves oily dirt, which is then washed away. This structure is stabilized by ion-dipole interactions. Detergents work similarly but with different head groups.

Question #3
In the extraction of iron, limestone is added as a flux to remove:
A. Silica (sand)
B. Iron oxide
C. Copper sulfide
D. Alumina

Correct Answer: Option A


Explanation:
In a blast furnace, limestone (CaCO₃) decomposes to CaO, which acts as a basic flux. It reacts with the acidic impurity silica (SiO₂) to form calcium silicate slag (CaSiO₃), which is lighter and floats on top of the molten iron, allowing it to be separated and removed.
