Which reaction below represents a balanced, double replacement chemical reaction? a) c2h5oh + 3o2 → 2co2 + 3h2o b) rb2o + cu(c2h3o2)2 → 2rbc2h3o2 + cuo c) 2al + 3h2so4 → 3h2 + al2(so4)3 eliminate d) 2h2o → 2h2 + o2

The correct answer is Option B.

Explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

For the given options:

The chemical equation follows:

This is a type of combustion reaction because an organic compound reacts with oxygen gas to produce carbon dioxide gas and water molecule

The chemical equation follows:

This is a type of double displacement reaction.

The chemical equation follows:

This is a type of single displacement reaction because a more reactive metal (aluminium) is replacing a less reactive metal (hydrogen).

The chemical equation follows:

This is a type of decomposition reaction because a single large compound is getting broken down to smaller substances.

Hence, the correct answer is Option B.

here are some of the ways in which chemical and nuclear reactions differ.
