Common Chemistry JAMB Questions
Below are examples of the types of questions you might encounter:
1. Mole Calculations
Question: How many moles are in 22 grams of CO₂?
Answer:
Use the formula:
Moles=MassMolar Mass\text{Moles} = \frac{\text{Mass}}{\text{Molar Mass}}
Molar mass of CO₂ = 12 + (16 × 2) = 44 g/mol.
Moles = 2244=0.5\frac{22}{44} = 0.5 moles.
2. Acid-Base Reactions
Question: Write the balanced equation for the reaction between HCl and NaOH.
Answer:
HCl + NaOH → NaCl + H₂O.
3. Gas Laws
Question: A gas occupies 2 L at 300 K. What will its volume be at 450 K, assuming pressure remains constant?
Answer:
Use Charles’ Law:
V1T1=V2T2\frac{V₁}{T₁} = \frac{V₂}{T₂}
Substitute values:
2300=V2450\frac{2}{300} = \frac{V₂}{450}
V2=2×450300=3V₂ = \frac{2 × 450}{300} = 3 L.
4. Periodic Table
Question: What is the electronic configuration of magnesium (Mg)?
Answer:
Magnesium has an atomic number of 12. Its electronic configuration is 1s22s22p63s21s^2 2s^2 2p^6 3s^2.
5. Chemical Bonding
Question: What type of bond exists in sodium chloride (NaCl)?
Answer: Ionic bond.
