Sample VCE Year 11 Chemistry questions

These sample questions are visible on the page before login. They show VCE Year 11 Chemistry particle models, bonding, stoichiometry, reaction profiles, rates, and acid-base data with diagrams, tables, curves, and spectra before opening the demo.

VCE Year 11 Chemistry Particle models hard particle model

1. A particle model for 2H2 + O2 -> 2H2O shows four H atoms and two O atoms before and after the reaction. What principle is being shown?

Choices

Atoms are conserved.
Oxygen atoms are destroyed.
Hydrogen changes into oxygen.
Mass can disappear.

Explanation:

The atoms are rearranged into water molecules, but the number of each type of atom is unchanged.

VCE Year 11 Chemistry Energy changes hard reaction profile

2. A reaction profile shows the products 64 kJ mol^-1 lower in energy than the reactants. Which statement best describes the reaction?

Choices

The reaction is exothermic.
The reaction is endothermic.
The reaction has no activation energy.
The products are less stable.

Explanation:

Products lower than reactants mean energy has been released to the surroundings.

VCE Year 11 Chemistry Bonding hard bond-polarity diagram

3. A bond-polarity diagram for H-Cl shows the electron-density arrow pointing toward chlorine. Which atom is partially negative?

Choices

Cl
H
Both atoms equally
Neither atom

Explanation:

Chlorine is more electronegative than hydrogen, so the bonding electrons are drawn closer to Cl.

VCE Year 11 Chemistry Reaction rates hard rate graph

4. A gas-volume graph for magnesium and acid is steep at first and then levels off at 48 mL. What does the steep initial section show?

Choices

The initial reaction rate is highest.
No reaction occurs at first.
The final gas volume is negative.
The acid concentration is increasing.

Explanation:

A steeper graph gradient means gas is being produced more quickly at that time.

VCE Year 11 Chemistry Stoichiometry hard stoichiometry table

5. A table shows the ratio 2Al : 3Cl2 : 2AlCl3. If 4.0 mol Al reacts completely, how many moles of Cl2 are needed?

Choices

6.0 mol Cl2
2.7 mol Cl2
4.0 mol Cl2
8.0 mol Cl2

Explanation:

The Al:Cl2 ratio is 2:3, so doubling 2.0 mol Al to 4.0 mol Al doubles chlorine from 3.0 mol to 6.0 mol.

VCE Year 11 Chemistry Acids and bases hard pH scale

6. Solution X has pH 2 and solution Y has pH 5. How many times greater is the hydrogen ion concentration in X?

Choices

1000 times
3 times
30 times
0.001 times

Explanation:

Each pH unit is a factor of 10. A difference of 3 pH units gives 10³ = 1000.

For parents comparing VCE Year 11 Chemistry support

VCE 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.
