Answer:
1. Combustion reactions: a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
2. Synthesis reactions:reactions that occur when two different atoms or molecules interact to form a different molecule or compound. ... Synthesis reactions are one of the major classes of chemical reactions, which include single displacement, double displacement, and combustion reactions.
3. Double displacement reactions: A double-replacement (or double-displacement) reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. Double-replacement reactions can form precipitates, gases, or molecular compounds.
