Transcript of TYPES OF CHEMICAL REACTIONS:

Synthesis- A reaction where two or more elements are combined
Decomposition- A reaction where a product is broken down into its reactants
Single Replacement- A reaction where reactants switch one partner
Double Replacement- A reaction where reactants switch both partners
What are the four main types of reactions?
In single replacement reactions, do any of the atoms change their charge? If yes, use an example from model 1 to describe the changes that take place.

Answer: None of the atoms change their charge.
Question #10
In double replacement reactions, do any of the atoms change their charge? If yes, use an example from model 1 to describe the changes that take place.

Answer: There is not a change in any of the atom's charges.
Question #11
During single and double replacement reactions, the charges on atoms are only rearranged. They are not being created or destroyed.
Why is the answer no?
Do atoms rearrange in predictable patterns during chemical reactions?
Types of Chemical Reactions:
Choose one example from the set of synthesis reactions in Model 1.
Question #12
2NH3 (g) N2(g) + 3H2(g)
A. Write the chemical reaction in reverse.
Answer: Decomposition. This is due to the fact that 2NH3 is being broken down.
B. Label the reaction written in part a with one of the reaction types in model 1.
