Displacement Reations

Question 1

Displacement reactions formula is..

Answer 1

A + AB —> AC + B

Question 2

What happens in a displacement reaction?

Answer 2

In a displacement reaction a more reactive element displaced (pushes out) a less reactive element

Question 3

A displace meant reaction only works when..

Answer 3

The element on its own is more reactive than the element compound

Question 4

In
Lead + copper sulfate —> lead sulfate + copper

Pb + CuSo4 —> PbSo4 + Cu

Why does lead displace copper?

Answer 4

Because lead is more reactive than copper
causing lead to displace

Question 5

Does this displacement reaction work?

Question 6

What makes a displacement reaction work?

Answer 6

When the single element is more reactive than the compound element

Question 7

Complete the displacement reaction..

Zinc + iron oxide —>

Answer 7

Zinc + iron oxide —> Zinc oxide + Iron

Question 8

Complete the displacement reaction..

Zinc + copper oxide —>

Answer 8

Zinc + copper oxide —> Zinc oxide + Copper

Question 9

What would this displacement reaction work?

MgSO4 (aq) + Zn(s) —>

Why?

Answer 9

No because the single element (Zn) has a lower reactivity than Compound element (Mg)

Question 10

What is this displacement reaction?

Fe(s) + CuSO4(aq) —>

Answer 10

Fe(s) + CuSO4(aq) —> FeSO4(aq) + Cu

Question 11

To displace the Single element must always be more reactive than what..

Answer 11

The compound element
