Question

What is the classification for this reaction? so3 (g) + h2o (l) → h2so4 (aq)?

Answer 1

There are six common types of reactions:

1. Combination
2. Decomposition
3. Single Displacement
4. Double Displacement
5. Combustion
6. Redox

The reaction: SO₃₍g₎ + H₂O₍l₎ → H₂SO₄₍aq₎ is classified as a combination reaction. This is because for combination reactions, two (or more) reactants form a single product. On the other hand, decomposition reactions involve a single reactant breaking down into two or more simpler substances. Displacement reactions involve a more active element displacing a less active element from a compound. Meanwhile, combustion reactions involve a carbon-containing compound reacting with oxygen to form carbon dioxide and water. Redox reactions then involve exchange of electrons between species.  

Answer 2

The given reaction is the combination reaction.

There are 6 different types of reaction namely, Combination , Decomposition , Single Displacement , Double Displacement , Combustion, and  Redox reactions.

The reaction given is :

$\rm SO_3\;+\;H_2O\;\rightarrow\;H_2SO_4$

In this reaction by the combination of two reactants, there is the formation of a single product. This type of reaction is the combination reaction. Thus, the given reaction is the combination reaction.
