1. Decomposition Reactions
- A compound breaks into parts.
- Eg. 2H2O → 2H2 + O2
- compound element + element
- Elements or compounds are joined together.
- Eg. 2H2 + O2 → 2H2O
- 6CO2 + 6H2O → C6H12O6 + 6O2
- element + element compound
- A single element replaces an element in a compound.
- Eg. Zn + 2HCl → H2 + ZnCl2
- element + compound element + compound
- An element from each of the two compounds switches places.
- Eg. H2SO4 + 2NaOH → Na2SO4 + 2H2O
- compound + compound compound + compound
- Special types of double displacement reactions that involve the reaction between an acid and base to form a salt and water.
* Heat is usually given off in neutralization reactions.
- Eg. A suspension of solid magnesium hydroxide in water is widely used
- as an antacid to neutralize excess stomach acid:
Mg(OH)2 (s) + 2HCl (aq) → MgCl2 (aq) + 2H2O (s)
- acid + base salt + water
- Aqueous reactions that involve the formation of a precipitate (solid).
- Eg. 2KI (aq) + Pb(NO3)2 (aq) → 2KNO3 (aq) + PbI2 (s)
- soluble compound + soluble compound insoluble compound
- An organic compound (containing only carbon, hydrogen or oxygen) combines with oxygen. The products of combustion are always carbon dioxide and water.
- Eg. CH4 + 2O2 → CO2 + 2H2O
- hydrocarbon + oxygen carbon dioxide + water
- Any reaction in which elements experience a change in oxidation number.
- Eg. S + O2 → SO2
- In this reaction, sulfur and oxygen both have an oxidation number (aka combining capacity) of zero before the reaction. After the reaction, sulfur is +4 and oxygen is -2.

What do you know about types of atoms before and after a reaction?
Assuming that you are referring to chemical reactions, we know that atoms are not changed by chemical reactions (except for their oxidation states). That means that all the same types of atoms are present after the reactions as were there before the reactions. The type of an atom is determined by the number of protons in its nucleus.
Two types of chemical reactions?
Two kind of chemical reactions are exothermic and endothermic reactions. An exothermic reaction is one that releases energy. An endothermic reaction is one that absorbs energy. Hope this helps!! :)
What are the three basic types of reaction mechanism?
Types of chemical reactions:- synthesis- decomposition- single displacement- double displacement

What Are 4 types of chemical reactions?
Chemical reactions are those that involve a chemical change and the products are usually different from the reactants. Such reactions are Decomposition, Synthesis, Single displacement and Double displacement.

How many types of chemical reactions are there?
normally there are a few chemical reactions the ones that i know of arecolour changeheat changefizzingbubblingthose are all i can remember sorryActually these aren't types of reactions. These are physical signs that a chemical reaction has taken place.
