Sample QCE Year 11 Chemistry questions
These sample questions are visible on the page before login. They show QCE Year 11 Chemistry particle models, bonding, stoichiometry, reaction profiles, rates, and acid-base data with diagrams, tables, curves, and spectra before opening the demo.
QCE Year 11ChemistryIonic reactionshardparticle model
1. A particle model shows Ag+ and Cl- ions meeting to form a white AgCl precipitate. What ratio of ions forms the solid?
Choices
1:1
2:1
1:2
3:2
Explanation:
AgCl contains one silver ion for each chloride ion.
QCE Year 11ChemistryStoichiometryhardstoichiometry table
2. The table shows Mg + 2HCl -> MgCl2 + H2. How many moles of HCl are required for 0.50 mol Mg?
Choices
1.00 mol HCl
0.25 mol HCl
0.50 mol HCl
2.00 mol HCl
Explanation:
The coefficient ratio is 1 mol Mg to 2 mol HCl, so 0.50 mol Mg needs 1.00 mol HCl.
QCE Year 11ChemistryRateshardrate graph
3. Two rate curves compare the same reaction at 25 C and 45 C. The 45 C curve is steeper at the start. What does this show?
Choices
Higher temperature increases the initial rate.
Temperature has no effect.
The 25 C reaction is faster.
No successful collisions occur.
Explanation:
At higher temperature, particles collide more often and with greater energy, so the initial rate is higher.
QCE Year 11ChemistryStructurehardLewis structure
4. A Lewis structure for water shows two O-H bonds and two lone pairs on oxygen. What shape does this help explain?
Choices
Bent
Linear with no lone pairs
Tetrahedral ion lattice
Square planar metal
Explanation:
The bonding pairs and lone pairs repel, producing a bent molecular shape for water.
QCE Year 11ChemistryEnergyhardreaction profile
5. An energy profile shows products above reactants. Which energy description matches the diagram?
Choices
Energy is absorbed.
Energy is released overall.
No bonds change.
The reaction has zero enthalpy change.
Explanation:
Products higher than reactants indicate an endothermic reaction overall.
QCE Year 11ChemistryAcid-base datahardpH scale
6. Sample A has pH 4 and sample B has pH 6. How many times greater is the hydrogen ion concentration in A?
Choices
100 times
2 times
20 times
0.01 times
Explanation:
A two-unit pH difference represents a factor of 102 in hydrogen ion concentration.
For parents comparing QCE Year 11 Chemistry support
QCE Year 11 Chemistry practice should help students connect chemical reasoning to visible evidence: particle models, bonding, stoichiometry, reaction profiles, rates, and acid-base data. These examples preview that visual reasoning before the no-login Chemistry demo.

A strong way to preview the full Skill Align practice flow
Want more than this sample set?
This public preview is intentionally small. Full access adds more practice sessions, broader topic coverage,
saved student history, and structured learning by year and subject.
Does this page include Year 11 QCE Chemistry practice questions?
Yes. This public demo includes reviewed Year 11 QCE Chemistry sample questions so families can preview the Skill Align practice style before regular use.
Can students try the demo without signing up?
Yes. The public demo can be opened without signing up, and the attempt stays in the page instead of being saved to a student record.
How does this demo relate to curriculum coverage?
This demo is linked with the QCE Year 11-12 Chemistry curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
