2. Single replacement
Doulble Replacement

3. What Part of Atoms are affected?
The electrons are affected during a chemical reaction because electrons are the linking's to other molecules.

4. What happens during a chemical reaction
During a Chemical Reaction the electrons are being redistributed. Wiki answers/chemicalreactions.com phycomp.technion.ac.il/~anastasy/diamgrap.png
The law of conservation says matter cannot be destroyed or created when there's a chemical reaction the matter is redistributed to a different place.
When a chemical reaction is occurring there might be fizzing bubbling or gases or heat.
Reactants are compounds or elements being consumed in a chemical reaction.
Products are substances that have been created by chemical reactions

5. Energy and Chemical reations
The role of energy in chemical reaction is to create work or an ability.
Potential energy is stored energy.
Activation is the energy that Initiates the combustion for example like stricking a match.
Endothermic is when a chemical reaction gets cold .
Exo endoreaction is when the chemical reaction gets hot.

6. Types of chemical reaction
Synthesis- when two elements or compounds combine. Example rust oxygen and iron
Decomposition- is when a chemical compound is separated into a smaller compound or element.
Combustion is a burning or a start of some sort of heat. A nuclear bomb.

7. Replacements Single replacement Doulble replacement
Single replacements takes one element with a chemical which changes into another element
Double replacement is when two cations and anions switch places with another compound.
