Example Questions
Example Question #1 : Types Of Reactions
Which of the following reactions is an example of an addition reaction?
Addition reactions follow the general pattern:
When magnesium combines with oxygen gas, it results in a compound with both of them in it. This makes it a simple addition reaction. In general, addition reactions have a greater number of reactant compounds than product compounds.
The other answer choices correspond to the reactions below:
Decomposition reaction:
Single-replacement reaction:
Double-replacement reaction:
Example Question #1 : Types Of Reactions
What is another term for an addition reaction?
Hydrolysis reaction
Synthesis reaction
Single-replacement reaction
Decomposition reaction
Double-replacement reaction
Synthesis reaction
Addition reactions occur when two molecules combine to form a larger one, leading to a release of energy. Addition reactions result in the synthesis of a new molecule, giving them their second name: synthesis reactions.
Many synthesis reactions can also be classified as dehydration reactions, if water is formed as a byproduct. One example of this is the addition of amino acids to form protein chains. Hydrolysis reactions use water as a reactant and are used to split molecules apart (decomposition).
