Sample TASC Year 11 Chemistry questions

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

TASC Year 11 Chemistry Collision theory hard particle model

1. A particle diagram shows more successful collisions when reactant concentration is higher. Which explanation matches the model?

Choices

Particles collide more frequently.
Particles stop moving.
The product side has no atoms.
pH becomes mass.

Explanation:

Increasing concentration puts more particles in the same volume, increasing collision frequency.

TASC Year 11 Chemistry Balanced equations hard stoichiometry table

2. The table shows 2Na + Cl2 -> 2NaCl. How many moles of Na react with 0.30 mol Cl2?

Choices

0.60 mol Na
0.30 mol Na
0.15 mol Na
2.30 mol Na

Explanation:

The mole ratio is 2 mol Na to 1 mol Cl2, so 0.30 mol Cl2 reacts with 0.60 mol Na.

TASC Year 11 Chemistry Molecular shape hard Lewis structure

3. A Lewis diagram for water shows two lone pairs on oxygen. What shape is most consistent with this diagram?

Choices

Bent
Linear with no lone pairs
Ionic lattice
Square planar

Explanation:

The lone pairs repel bonding pairs, so water has a bent shape.

TASC Year 11 Chemistry Activation energy hard reaction profile

4. A reaction profile marks a peak above the reactants. What does the gap from reactants to peak represent?

Choices

Activation energy
pH
Molar mass
A salt bridge

Explanation:

Activation energy is the minimum energy barrier for a successful reaction pathway.

TASC Year 11 Chemistry Rates hard rate graph

5. A product-volume graph rises and then flattens. What is the most likely reason the graph becomes flat?

Choices

A reactant has been used up.
The product has no mass.
The graph turns into pH.
The flask creates atoms.

Explanation:

When the limiting reactant is used up, no more product is formed and the graph levels off.

TASC Year 11 Chemistry Acids hard pH scale

6. A solution is marked at pH 3 on the scale. Which description is correct?

Choices

It is acidic.
It is strongly basic.
It is neutral at all temperatures.
It is a molecular ion peak.

Explanation:

Values below pH 7 are acidic.

For parents comparing TASC Year 11 Chemistry support

TASC 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.
