Year 11 WACE Chemistry practice questions
This public preview page identifies the planned Year 11 WACE Chemistry demo route and links it to curriculum coverage while the reviewed sample question set is being completed.
Sample-question focus
The planned public sample is for Year 11 WACE Chemistry practice and will open after the demo questions are reviewed.
Skills covered
Practice atomic structure, bonding, chemical reactions, stoichiometry, equilibrium, acids and bases, organic chemistry, analysis, and modelling.
Exercise and test mode
The route is public now; the exercise and test preview will become available after the curated question set is ready.
Curriculum link
Compare this demo with the WA Year 11-12 Chemistry curriculum page to scan related topics, subtopics, and pathway coverage.
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 11ChemistrySolutionshardparticle 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 11ChemistryQuantitative chemistryhardstoichiometry 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 11ChemistryBondinghardbond-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 11ChemistryCatalystshardreaction 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 11ChemistryRateshardrate 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 11ChemistryAcidshardpH 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.
This demo is in progress
In progress
Year 11 WACE Chemistry is available to purchase, and the public demo preview is still being prepared.
Students can use the purchased subject once subscribed; this anonymous preview will be opened after the curated public question set is ready.
Does this page include Year 11 WACE Chemistry practice questions?
Not yet. The Year 11 WACE Chemistry demo route is public, but the interactive sample questions will open after the reviewed public set is ready.
Can students try the demo without signing up?
No sign-up is required to view the preview status. The no-login interactive demo will be available after the sample set is completed.
How does this demo relate to curriculum coverage?
This demo is linked with the WA Year 11-12 Chemistry curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
