A reducing agent is one which is oxidised in the reaction itself. When you take into account the oxidation numbers you will see that the Cl- ions are oxidised from an oxidation number of -1 to 0 in Cl2. Therefore Cl- ions are the reducing agent.
Whether water is frozen, in a gaseous state, or is a liquid, it is still H2O. So the chemical composition does stay the same.
Elements in the same group have similar reactivities. For example, elements in group 1 are highly reactive, since they can all take in 7 electrons. Hope I helped!
Answer:
Combination reaction or synthesis reaction
Explanation:
Given reaction:
CO + H₂O → H₂CO₃
The type of reaction shown above is a combination or synthesis reaction. A combination reaction is one in which a single product is formed from two or more reactants.
In the given reaction carbon monoxide combines with water to produce hydrogen carbonate.
The formation of compounds from the union of their constituent elements falls into this category of reactions.
