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) Identify what has been reduced in the reaction below.

1/7

Q2.(Revision) To investigate the reactivity of metals a student uses four different metals. Each time they added 1 g of the metal to 25 cm³ of sulfuric acid and record the temperature change. Identify the control variables in this example. You need to select two answers.

Select two (2) boxes

Q3.(Revision) What is the general word equation for the reaction between a metal and an acid?

3/7

Q4.Which is the correct definition of a displacement reaction?

4/7

Q5.Students investigated the reactivity of metals by adding them to salt solutions of each metal and recording whether a reaction took place. Their results are below. Use the results to place the metals in order of reactivity from MOST reactive to LEAST reactive.
