The list shows the order of reactivity of some elements. K Na Ca Mg Zn Fe (H) N Which statement about the reactivity of these metals is correct?

• Copper reacts with steam to form hydrogen gas.

• Magnesium is more reactive than calcium.

• Potassium reacts with water to form hydrogen gas.

• Sodium oxide is reduced by carbon to sodium.

Which substances do not react together?

• calcium + water

• copper + dilute hydrochloric acid

• sodium + water

The diagrams show what happens when three different metals are added to water. What are X, Y and Z?

• calcium, copper, potassium

• copper, calcium, potassium

• potassium, calcium, copper

• potassium, copper, calcium

Samples of five different metals, E, F, G, H and J were reacted with dilute sulfuric acid. The volume of hydrogen gas collected after one minute was measured. The results are shown on the bar chart. What is the order of reactivity of the metals (most reactive first)?

• E, F, G, H, J

• G, E, H, F, J

• J, F, H, E, G

• J, H, G, F, E

Using the information, where should hydrogen be placed in the reactivity series?

• below copper

• between sodium and calcium

• between calcium and zinc

• between zinc and copper

The table shows the reactions of four different metals with water. What is the correct order of reactivity, from most reactive to least reactive?

• W → X → Y → Z

• W → Z → Y → X

• Z → W → X → Y

• Z → W → Y → X

In an experiment, three test-tubes labelled X, Y and Z were half-filled with dilute hydrochloric acid. A different metal was added to each test-tube. After a few minutes the following observations were made.

In tube X, bubbles slowly rose to the surface.

In tube Y, there was a rapid release of bubbles.

In tube Z, no bubbles were produced.

Which three metals match the observations?

• A

• B

• C

• D

What is the order of reactivity of the four metals, starting with the most reactive first?

• Q → R → T → S

• Q → T → R → S

• S → R → Q → T

• S → R → T → Q
