Sample WACE Year 11 Chemistry questions

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

WACE Year 11 Chemistry Solutions hard particle model

1. A particle model shows NaCl separating into hydrated Na+ and Cl- ions in water. Which process is shown?

Choices

Dissociation in water
Combustion
Polymerisation
Nuclear fission

Explanation:

The ionic lattice separates into ions that become surrounded by water molecules.

WACE Year 11 Chemistry Quantitative chemistry hard stoichiometry table

2. For CH4 + 2O2 -> CO2 + 2H2O, how many moles of O2 are needed to burn 0.25 mol CH4?

Choices

0.50 mol O2
0.25 mol O2
1.00 mol O2
2.25 mol O2

Explanation:

The ratio is 1 mol CH4 to 2 mol O2, so 0.25 mol CH4 needs 0.50 mol O2.

WACE Year 11 Chemistry Bonding hard bond-polarity diagram

3. A bond-polarity diagram for an O-H bond shows electron density closer to oxygen. Which atom is partially negative?

Choices

Oxygen
Hydrogen
Both atoms are metals
Neither atom has charge

Explanation:

Oxygen attracts the bonding electrons more strongly than hydrogen.

WACE Year 11 Chemistry Catalysts hard reaction profile

4. A reaction profile shows activation energy falling from 80 to 45 kJ mol^-1 when a catalyst is used. By how much is the activation energy lowered?

Choices

35 kJ mol^-1
45 kJ mol^-1
80 kJ mol^-1
125 kJ mol^-1

Explanation:

The decrease is 80 - 45 = 35 kJ mol^-1.

WACE Year 11 Chemistry Rates hard rate graph

5. A graph compares marble chips and marble powder reacting with acid. The powder curve is steeper. Which factor explains the faster rate?

Choices

Greater surface area
Lower collision frequency
Less contact with acid
No reaction

Explanation:

Powder exposes more surface area to acid, causing more frequent successful collisions.

WACE Year 11 Chemistry Acids hard pH scale

6. A mine-water sample at pH 1 is compared with creek water at pH 4. How many times greater is the hydrogen ion concentration in the mine-water sample?

Choices

1000 times
4 times
300 times
0.001 times

Explanation:

A three-unit pH difference corresponds to a factor of 10³.

For parents comparing WACE Year 11 Chemistry support

WACE 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.
