# Intro quiz - Recap from previous lesson

Before we start this lesson, let’s see what you can remember from this topic. Here’s a quick quiz!

Q1.(Revision) What is the name for the variable that is changed in an investigation?

1/6

Q2.(Revision) Three metals A, B and C were added to a solution of copper sulfate and the temperature change was recorded. The results are as follows A = 10⁰C, B = 0⁰C and C=22⁰C. Use the results to place the metals in order of reactivity from MOST to LEAST reactive.

2/6

Q3.Which of the following would NOT be an observation made in the reaction below? (HINT use the state symbols to help)

3/6

Q4.Which is the correct description of the test for carbon dioxide?

4/6

Q5.What would be the formula of a salt made from magnesium ions, Mg²⁺, and sulfate ions, SO₄²⁻?

5/6

Q6.What would be the formula of a salt made from calcium ions, Ca²⁺, and chloride ion, Cl⁻?
