2. You can classify reactions into different types. There are many different types of chemical reactions there are Synthesis, decomposition, single and double replacement and also a combustion reaction.

3. A single replacement reaction is when one element takes the place of another element in a compound. The general form is A + BC B + AC Usually when these reactions happen it is a solid being added to a solution. An example is this copper wire in a silver nitrate solution the solution turns blue and the copper wire has silver crystals on it.

4. A double replacement reaction is when two different compounds exchange positive ions and form two new compounds. This is the general form of a double replacement reaction. In order for a double replacement reaction to occur both elements must be soluble in water They usually take place when two solutions are mixed together

5. Reduction is when an element gains electrons during a chemical reaction. Reduction occurs when the oxidation number of an atom decreases.

6. Combustion Reaction A combustion reaction is when a substance reacts with oxygen. The reaction takes place when a fuel and oxidant react which produces heat or heat and light. The most recognizable form of a combustion is a flame

7. Oxidation is any process when an element loses electrons during a chemical reaction. An example of this would be calcium reacting with oxygen.

8. A synthesis reaction is a reaction when two or more substances react to form a single substance. For the reaction to work there has to be a cation and an anion An example of this would be sodium metal reacting with chlorine to form sodium chloride. 2Na(s) + Cl 2 (g) 2NaCl(cr)

9. A decomposition reaction is a reaction when a compound breaks down into two simpler substances. This reaction often requires exposure to a catalyst such as heat or a solvent. An example would be water being broken down into hydrogen and oxygen.

10. 1. Name two types of reactions. 2. What happens during oxidation. 3. What does a synthesis reaction require for it to react. 4. Give an example of a decomposition reaction 5. What does a combustion reaction produce Next five are true or false 1. A decomposition reaction is when a compound breaks down into simpler substances 2. A combustion reaction is when it reacts with magnesium 3. Reduction is when an element loses electrons 4. Double replacement reaction is when compounds exchange positive ions 5. A synthesis reaction forms a single substance
