Answer:

1. Double displacement.

2. Combustion.

3. Simple displacement.

4.Double displacement.

Explanation:

Hello,

1. [tex]2HBr(aq)+Ba(OH)_2(aq) -->2H_2O(l)+BaBr_2(aq)[/tex]

In this case, it is about a double displacement reaction since all the cations (H and Ba) and anions (Br and OH) are exchanged.

2. [tex]C_2H_4(g)+3O_2(g)-->2CO_2(g)+2H_2O(l)[/tex]

In this case, it is about the combustion of ethene.

3. [tex]Cu(s)+FeCl_2(aq)-->Fe(s)+CuCl_2(aq)[/tex]

In this case, it is about a simple displacement reaction since the iron (II) cations become solid iron and on the contrary for copper.

4. [tex]Na_2S(aq)+2AgNO_3(aq)-->2NaNO_3(aq)+Ag_2S(s)[/tex]

Finally, it is about a double displacement chemical reaction since the sodium and silver cations are exchanged with the sulfide and nitrate anions.

Best regards.
