The second reaction is a redox reaction
To classify each of the reactions, we need to determine the type of reaction that is occurring.
1. C2H4(g) + 3O2(g) -> 2CO2(g) + 2H2O(l)
This is an example of a combustion reaction, where a hydrocarbon (C2H4) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).
2. Cu(s) + FeCl2(aq) -> Fe(s) + CuCl2(aq)
This reaction is an example of a single displacement reaction, also known as a substitution reaction or a redox reaction. In this reaction, copper (Cu) is displacing iron (Fe) from the compound FeCl2 to form CuCl2 while iron is being displaced and forming Fe.
3. HI(aq) + LiOH(aq) -> H2O(l) + LiI(aq)
This reaction is a classic example of an acid-base neutralization reaction. Hydroiodic acid (HI) and lithium hydroxide (LiOH) react to produce water (H2O) and lithium iodide (LiI). The hydrogen from the acid combines with the hydroxide from the base to form water, and the remaining ions form a new compound.
To summarize:
- Reaction 1 is a combustion reaction.
- Reaction 2 is a single displacement (redox) reaction.
- Reaction 3 is an acid-base neutralization reaction.
