Q1.The periodic table is arranged in order of increasing:
Show answer & explanation
Answer: D — Atomic number
The modern periodic table orders elements by atomic number.
-
Q2.What is the mass of 0.5 mol of water (H₂O)? (Molar mass 18 g/mol)
Show answer & explanation
Answer: C — 9 g
Mass = moles × molar mass = 0.5 × 18 g/mol = 9 g.
-
Q3.Which element is liquid at room temperature?
Show answer & explanation
Answer: C — Mercury
Mercury (and bromine) are liquids at room temperature.
-
Q4.36.5 g of KCl (molar mass 74.5) is dissolved to make 500 mL of solution. Find the molarity.
Show answer & explanation
Answer: B — 0.98 M
Moles = 36.5/74.5 = 0.49; molarity = moles ÷ litres = 0.49 ÷ 0.5 = 0.98 M.
-
Q5.Avogadro’s number is approximately:
Show answer & explanation
Answer: B — 6.022 × 10²³
One mole contains 6.022 × 10²³ particles.
-
Q6.What is the pH of a solution with [H⁺] = 10⁻³ mol/L?
Show answer & explanation
Answer: C — 3
pH = −log[H⁺] = −log(10⁻³) = 3.
-
Q7.The noble gas used in advertising signs that glows red-orange is:
Show answer & explanation
Answer: C — Neon
Neon glows red-orange in discharge tubes.
-
Q8.What is the pH of a solution with [H⁺] = 10⁻² mol/L?
Show answer & explanation
Answer: D — 2
pH = −log[H⁺] = −log(10⁻²) = 2.
-
Q9.The main component of natural gas is:
Show answer & explanation
Answer: C — Methane
Methane (CH₄).
-
Q10.What is the mass of 4 mol of ammonia (NH₃)? (Molar mass 17 g/mol)
Show answer & explanation
Answer: D — 68 g
Mass = moles × molar mass = 4 × 17 g/mol = 68 g.
How to approach chemistry questions
Moles = mass ÷ molar mass; molarity = moles ÷ litres. pH = −log[H⁺] and pH + pOH = 14 at 25 °C. For concepts, link each property to its position in the periodic table.
