Free Year 11 VCE Chemistry Quiz — 10 Questions, Instant Results

What Year 11 students need to know about VCE Chemistry

A short orientation first. VCE Chemistry Units 1 and 2 covers atomic structure and bonding, the mole, quantitative chemistry, reactions in water and analysis.

Our tutors wrote and checked these questions against the VCE study design, which is why the wording and the difficulty match what a Year 11 student meets at school.

The usual VCE Chemistry errors at Year 11

If your child gets a question wrong here, it is worth checking whether one of these is behind it. They are the VCE Chemistry misconceptions RHZ tutors correct most often with Year 11 students:

• Units are dropped in calculations.
• Moles and mass are confused.
• Equilibrium is thought to mean equal concentrations.

None of these is a sign of low ability. Each is a reasonable idea that worked in an earlier year and needs replacing, which is exactly what a good explanation, or a tutor, does.

How to practise VCE Chemistry at home

Practice works when it is short, regular and specific. For VCE Chemistry, our tutors suggest:

1. Name organic compounds from structures.
2. Keep a formula and unit sheet.
3. Practise mole calculations daily.

For VCE science, learn the command terms, draw diagrams from memory and practise data-analysis questions until the working is automatic.

How the 10 questions are chosen

We keep 25 VCE Chemistry questions for Year 11 that meet our standard, at the easy and at-level tiers, and this page serves 10 of them at a time. The default set is stable, so a teacher or parent can share the link; a fresh set is one click away. Marking happens on our server so the answer key cannot be read from the page.

A single-topic quiz is more precise than a mixed one: if the score here is low, the gap is in VCE Chemistry, not somewhere in Year 11 science generally. It is still short, though, and it cannot show how a student copes with the stretch and challenge questions that decide a top result. That is what the free Skills Check adds.

Question 1

VCE Chemistry

An atom of magnesium-25 has 12 protons. How many neutrons does it contain?

24 13 12 25

Question 2

VCE Chemistry

The pH scale runs from…

0 to 100 0 to 14 1 to 10 −7 to 7

Question 3

VCE Chemistry

The Haber process produces ammonia: N₂(g) + 3H₂(g) ⇌ 2NH₃(g) ΔH = −92 kJ mol⁻¹. In a sealed 2.00 L container at a fixed temperature, the equilibrium concentrations are: [N₂] = 0.30 mol L⁻¹, [H₂] = 0.90 mol L⁻¹, [NH₃] = 0.60 mol L⁻¹. The temperature is then raised. Which of the following correctly predicts both the direction of shift AND the new value of Kc relative to the original?

The equilibrium shifts left (towards reactants) but Kc remains unchanged because the container volume is fixed. The equilibrium shifts right (towards products) and Kc increases. The equilibrium shifts left (towards reactants) and Kc decreases. The equilibrium shifts right (towards products) but Kc remains unchanged because a catalyst is implicitly operating at higher temperature.

Question 4

VCE Chemistry

A catalyst in a reaction…

Slows it down Is used up Speeds it up without being consumed Changes the products

Question 5

VCE Chemistry

Which of the following is the correct balanced equation for the combustion of methane?

CH₄ + 2O₂ → CO₂ + 2H₂O 2CH₄ + O₂ → 2CO₂ + 4H₂O CH₄ + O₂ → CO₂ + H₂O CH₄ + 2O₂ → CO₂ + H₂O

Question 6

VCE Chemistry

Elements in the same group have the same number of…

Valence electrons Protons Shells Neutrons

Question 7

VCE Chemistry

An element X is in Group 16 (Group VI) of the periodic table. How many electrons are in its outer (valence) shell?

6 16 8 2

Question 8

VCE Chemistry

A chemist dissolves a sample of sodium carbonate (Na₂CO₃, molar mass = 106 g mol⁻¹) in water to make 250 mL of solution. The solution has a pH of 11.70 at 25 °C. Which of the following correctly explains why the solution is basic AND identifies the relevant equilibrium?

The carbonate ion (CO₃²⁻) acts as a Brønsted–Lowry base, accepting a proton from water to form HCO₃⁻ and OH⁻, raising the pH above 7. Sodium ions (Na⁺) hydrolyse in water to release H⁺ ions, but these are outnumbered by OH⁻ from the dissolved carbonate solid, giving a net basic solution. Na₂CO₃ is a strong base that fully dissociates to release OH⁻ ions directly; no further equilibrium is needed. CO₃²⁻ donates a proton to water to form HCO₃⁻ and H⁺; because HCO₃⁻ is a weak acid, the net solution becomes basic.

Question 9

VCE Chemistry

What is the molar mass of water (H₂O)? Use H = 1.0 and O = 16.0 g/mol.

17.0 g/mol 16.0 g/mol 18.0 g/mol 34.0 g/mol

Question 10

VCE Chemistry

Which pair of atoms are isotopes of the same element?

An atom with 6 protons and 6 neutrons, and one with 8 protons and 6 neutrons An atom with 6 protons and 6 neutrons, and one with 6 protons and 6 electrons An atom with 6 protons and 6 neutrons, and one with 6 protons and 8 neutrons An atom with 6 protons and 6 neutrons, and one with 7 protons and 6 neutrons

How to read a score out of 10

9 or 10 out of 10

The easy and at-level content is secure. The useful question now is how far above the year level the student can go, which a ten-item quiz cannot show. The free Skills Check adds stretch and challenge questions on every topic so you can see the ceiling as well as the floor.

7 or 8 out of 10

Solid, with one or two specific gaps. Look at which topic the incorrect answers came from (the results panel names the weakest topic) and spend a week on that topic before re-testing with a different seed.

5 or 6 out of 10

Some core ideas are shaky. The pattern matters more than the score: two misses in the same topic is a gap; misses scattered across topics usually means reading the question too fast. Either way, the Skills Check will tell you which.

4 or fewer out of 10

Foundations from an earlier year are probably missing, which is common and fixable. Try the quiz one year level down to confirm, then talk to a tutor about a short catch-up plan rather than more of the same practice.
