Answer: D — Sodium bicarbonate (sodium hydrogen carbonate)
Baking soda is NaHCO₃.
-
Q3.PhysicsThe phenomenon responsible for the blue colour of the sky is:
Answer: A — Rayleigh scattering

Q5.BiologyWhich disease is caused by a deficiency of iodine?
Answer: B — Goitre
Iodine deficiency causes goitre (thyroid enlargement).
-
Q6.ChemistryWhat is the mass of 1.5 mol of water (H₂O)? (Molar mass 18 g/mol)
Answer: C — 27 g
Mass = moles × molar mass = 1.5 × 18 g/mol = 27 g.
-
Q7.PhysicsA body with initial velocity 11 m/s accelerates at 2 m/s² for 2 s. Find the distance covered.
Answer: C — 26 m
s = ut + ½at² = 11×2 + ½×2×2² = 26 m.
-
Q8.Verbal Reasoning & AnalogiesFind the next number in the series: 2, 4, 8, 16, 32, ?
Answer: A — 64
Each term is multiplied by 2.
-

Answer: B — Pancreas
Beta cells of the pancreatic islets of Langerhans secrete insulin.
-
Q10.ChemistryWhich gas is produced when zinc reacts with dilute hydrochloric acid?
Answer: B — Hydrogen
Zn + 2HCl → ZnCl₂ + H₂.
-
Q11.PhysicsThe SI unit of force is the:
Answer: C — Newton
1 newton = 1 kg·m/s².
-
Q12.Verbal Reasoning & AnalogiesStatements: All cats are animals. All animals have legs. Conclusion: All cats have legs.
Answer: D — Follows
Cats ⊂ animals ⊂ things with legs, so all cats have legs.
-
Q13.BiologyWhich part of the brain controls balance and coordination?
Answer: A — Cerebellum
The cerebellum coordinates movement and balance.
-
Q14.ChemistryWhat is the mass of 2 mol of sodium chloride (NaCl)? (Molar mass 58.5 g/mol)
Answer: D — 117 g
Mass = moles × molar mass = 2 × 58.5 g/mol = 117 g.
-
Q15.PhysicsA current of 1.5 A flows through a 25 Ω resistor. What is the potential difference across it?
Answer: B — 37.5 V
Ohm’s law: V = IR = 1.5 × 25 = 37.5 V.
-
Q16.Verbal Reasoning & AnalogiesFind the next number in the series: 25, 36, 49, 64, 81, ?
Answer: C — 100
Squares of consecutive numbers: 5², 6², … → 10² = 100.
-
Q17.BiologyThe largest organ of the human body is the:
Answer: C — Skin
The skin is the largest organ by area and weight.
-
Q18.ChemistryAn oxidation reaction involves:
Answer: B — Loss of electrons

Q21.BiologyThe functional unit of the kidney is the:
Answer: A — Nephron
Each kidney has about a million nephrons that filter blood.
-
Q22.Chemistry58.5 g of HCl (molar mass 36.5) is dissolved to make 250 mL of solution. Find the molarity.
Answer: C — 6.411 M
Moles = 58.5/36.5 = 1.603; molarity = moles ÷ litres = 1.603 ÷ 0.25 = 6.411 M.
-
Q23.PhysicsA body starts at 9 m/s and accelerates uniformly at 3 m/s² for 3 s. Find its final velocity.
Answer: C — 18 m/s
v = u + at = 9 + 3×3 = 18 m/s.
-
Q24.Verbal Reasoning & AnalogiesFind the next number in the series: 16, 25, 36, 49, 64, ?
Answer: A — 81
Squares of consecutive numbers: 4², 5², … → 9² = 81.
-
Q25.BiologyWhich organelle synthesises proteins?
Answer: B — Ribosome
Ribosomes translate mRNA into protein.
How the mock test works
- The timer starts with your first answer; the test submits itself when time runs out.
- Choose the negative marking that matches your exam (this test has no negative marking by default — check the official notification).
- After submitting you get your score, accuracy, time taken and a topic-wise breakdown, then every explanation.
- “New mock test” builds another paper — calculation questions get new numbers.
