Classify each of these reactions. Pb ( NO 3 ) 2 ( aq ) + 2 KCl ( aq ) ⟶ PbCl 2 ( s ) + 2 KNO 3 ( aq ) C 2 H 4 ( g ) + 3 O 2 ( g ) ⟶ 2 CO 2 ( g ) + 2 H 2 O ( l ) Cu ( s ) + FeCl 2 ( aq ) ⟶ Fe ( s ) + CuCl 2 ( aq ) 2 KOH ( aq ) + H 2 SO 4 ( aq ) ⟶ K 2 SO 4 ( aq ) + 2 H 2 O ( l )

For a: The reaction is a double displacement reaction.

For b: The reaction is a combustion reaction.

For c: The reaction is a single displacement reaction.

For d: The reaction is a neutralization reaction.

Explanation:

For the given equations:

Equation 1:

This reaction is an example of double displacement reaction because here exchange of ions takes place.

Equation 2:

This reaction is an example of combustion reaction because here hydrocarbon is reacting with oxygen gas to produce carbon dioxide gas and water molecule

Equation 3:

This reaction is an example of single displacement reaction because here more reactive element displaces a less reactive element.

Equation 4:

This reaction is an example of neutralization reaction because here a base reacts with an acid to produce a salt and water molecule

take a better picture and ill do it

i wish i could but this one is weird give me abc and i can solve it.
