Sample exam questions - chemicals of the natural environmentMultiple choice questions

Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple-choice, structured, mathematical and practical questions.

Multiple choice questions

Multiple choice questions will appear throughout both exam papers, and at both Foundation tier and Higher tier.

These questions provide you with a number of answers, from which you must select the answer or answers that you think are correct.

The question may tell you in bold how many ticks, rings or lines to draw. If you draw less than this, or more than this, you will not be able to get full marks. Make sure that you draw straight lines rather than complex wavy lines.

There will usually be more options than correct answers. Don't just go for the first option that looks correct - read each option carefully and decide whether it is right or wrong.

These questions have been written by Bitesize consultants as suggestions to the types of questions that may appear in an exam paper.

Sample question 2 - Foundation

Question

Electrolysis of a solution produces a product at the anode and at the cathode.

Draw straight lines to join the solution with the correct products of electrolysis. [3 marks]

Four descriptions and four sets of elements

Sample question 3 - Foundation

Question

Fractional distillation separates a mixture into a number of different parts, called fractions.

These are some of the fractions of crude oil. They are not in the correct order:

A heavy gas oil (fuel oil)

B bitumen

C petroleum gas

D light gas oil (diesel)

E kerosene

Re-write the list to put them in the order in which they are removed from the fractionating column, starting at the bottom. The first one is B bitumen. [3 marks]

Sample question 4 - Higher

Question

Magnesium displaces copper from copper sulfate solution.

Put a tick (鉁) in the box next to the correct ionic equation for this reaction. [1 mark]
