C2 Past Paper Questions

This is a 20 minute timed powerpoint with a small selection of questions from a past paper.

The idea behind this powerpoint is to highlight that with the AQA C2 exam there will be 45 marks available in a 45 minute paper. Many students rush through the paper, leaving lots of spare time at the end, and yet still find they have made 'silly' mistakes which they could/should have got right.

The slideshow is timed. You'll need to make sure you've got a periodic table & calculator to hand. Start the slideshow (before you're tempted to look ahead!) and then click start. Each slide will be shown for 1 minute per mark available.

RESIST the urge to skip ahead. This is a thinking exercise as much as it is a question exercise. Let your eyes roam around the question. Re-read it. Be strict with yourself.

At the end of the slideshow is a slide (not timed) which will help you review and evaluate this method. Think it through, did this help you to complete all of each question? Did you find you could have spent less time on some questions, to allow you more time on the trickier ones? Did it help your anxiety levels, or make them worse?

When you've completed the powerpoint show, you can look at the notes section for each slide to find the answers. 

Good luck, & I hope this helps!

1 This label was taken from a cola drink.
The pH of this drink is 2.5.
1 (a) (i) Which one of the ingredients in the cola drink causes the low pH?

Here's a taster:

1 (b) The preservative used in the cola drink is sodium benzoate.
Sodium benzoate is made using two chemical reactions.
Reaction 1
Methylbenzene is reacted with oxygen, with the help of a catalyst, to form
benzoic acid.
Reaction 2
Benzoic acid is neutralised by sodium hydroxide solution to form sodium
benzoate and water.
1 (b) (i) How does the catalyst help reaction 1?

Here's a taster:

1 (b) (ii) Reaction 1 has a high atom economy.
The table lists several statements. Put a tick () next to
the one statement which best describes a high atom
economy.
Statement ()
A: All the atoms used are cheap.
B: Most of the starting materials end up as useful
products.
C: Only a small number of atoms are used in the
reaction.

3 Bricks made from silica (silicon dioxide) are used to line furnaces that
operate at high temperatures.
Part of the structure of silica is shown in the diagram.
covalent giant
low small
four high
six weak
Use words from the box to complete the sentences:
One reason for using silica to make bricks for high-temperature furnaces is that
silica has a A:............................... melting point. Silica has this property
because it is a B:............................... structure in which each silicon atom is
joined to C:............................... oxygen atoms by D:...............................
bonds.
