When magnesium reacts with copper sulphate, there are two products. What are they?

Magnesium Sulphate and Copper Sulphate

When copper and magnesium sulphate are mixed together, there is no reaction. Why?

Magnesium is more reactive than copper

Copper is more reactive than magnesium

Copper never reacts with metal salts

Magnesium Sulphate never reacts with metals

Another useful property of metals is that they are ductile. What does this mean?

They can be stretched into wires

When metal reacts with liquid water the products are...

metal hydroxide and hydrogen gas

Which are the signs of chemical change?

Precipication (an insoluble solid forms from the solution)

What does displacement mean?

A chemical reaction where a more reactive metal takes the place of a less reactive metal in a compound.

A chemical reaction where a less reactive metal takes the place of a more reactive metal in a compound.

A more reactive metal is removed from a compound.

Magnesium chloride + Sodium → ?

Magnesium chloride + Sodium (No change)

Lithium chloride + Iron → ?

Lithium chloride + Iron (No change)

The correctly balanced equation for the following reaction: Fe 2 O 3(s) + Al (s) → Al 2 O 3(s) + Fe (l) would be:

Fe 2 O 3(s) + 2Al (s) → Al 2 O 3(s) + 2Fe (l)

Fe 2 O 3(s) + Al (s) → Al 2 O 3(s) + Fe (l)

Fe 2 O 3(s) + 3Al (s) → 2Al 2 O 3(s) + 2Fe (l)

2Fe 2 O 3(s) + 4Al (s) → 2Al 2 O 3(s) + 4Fe (l)

The correctly balanced equation for the following reaction Copper Sulfate + Iron → \rightarrow → Iron Sulfate + Copper would be:

C u S O 4 + F e → F e S O 4 + C u CuSO_4+\ Fe\ \rightarrow\ FeSO_4+\ Cu C u S O 4 + F e → F e S O 4 + C u

C u S O 4 + 2 F e → F e 2 S O 4 + C u CuSO_4\ +\ 2Fe\ \ \rightarrow\ \ Fe_2SO_4\ +\ Cu\ C u S O 4 + 2 F e → F e 2 S O 4 + C u

C u S O 4 + 2 F e → F e 2 S O 3 + C u O CuSO_4+\ 2Fe\ \rightarrow\ Fe_2SO_3+\ CuO C u S O 4 + 2 F e → F e 2 S O 3 + C u O

C u S O 3 + 2 F e → F e 2 S O 3 + C u CuSO_3+\ 2Fe\ \rightarrow\ Fe_2SO_3+\ Cu C u S O 3 + 2 F e → F e 2 S O 3 + C u

No reaction takes place as copper is less reactive than iron

The correct chemical formula for the compound: Copper (II) Carbonate is:

C u 2 C O 3 Cu_2CO_3 C u 2 C O 3

C u 3 C O 3 Cu_3CO_3 C u 3 C O 3

The correct chemical formula for the compound: Copper (I) Carbonate is:

C u 2 C O 3 Cu_2CO_3 C u 2 C O 3

C u 3 C O 3 Cu_3CO_3 C u 3 C O 3

The correctly balanced equation for the reaction: Iron (III) oxide + Carbon → Iron + Carbon dioxide is:

2 F e 2 O 3 + 3 C → 4 F e + 3 C O 2 2Fe_2O_3\ \ +\ \ 3C\ \ \rightarrow\ \ 4Fe\ \ +\ \ 3CO_2 2 F e 2 O 3 + 3 C → 4 F e + 3 C O 2

2 F e O + C → 2 F e + C O 2 2FeO\ \ +\ C\ \ \rightarrow\ \ 2Fe\ \ +\ \ CO_2 2 F e O + C → 2 F e + C O 2

F e O 2 + C → F e + C O 2 FeO_2\ \ +\ C\ \ \rightarrow\ \ Fe\ \ +\ \ CO_2 F e O 2 + C → F e + C O 2

F e 2 O 3 + C → 2 F e + 2 C O 2 Fe_2O_3\ \ +\ C\ \ \rightarrow\ \ 2Fe\ \ +\ 2CO_2 F e 2 O 3 + C → 2 F e + 2 C O 2

The correct chemical formula for the compound: Copper(II) Nitrate is:

C u ( N O 3 ) 2 Cu\left(NO_3\right)_2 C u ( N O 3 ) 2

C u 2 N O 3 Cu_2NO_3 C u 2 N O 3

C u 2 ( N O 3 ) 3 Cu_2\left(NO_3\right)_3 C u 2 ( N O 3 ) 3
