Physical Science, Chapter 11, Types of Reactions
What is the fancy name for a reaction that produces heat?
exothermic
In addition to the production of water and carbon dioxide, what else is produced in combustion?
heat
What type of chemical reaction do you have when one element trades places with another element in a compound?
single displacement
What type of chemical reaction is this: 2 Fe + 6 NaBr → 2 FeBr₃ + 6 Na
single displacement
Can a combustion reaction occur with oxygen by itself?
No - oxygen must combine with another compound for combustion to happen.
In a single displacement chemical reaction, how many elements trade places?
1
In a synthesis reaction, how many products form?
1 (that is why it is called "synthesis", because it brings things TOGETHER)
Chemical reactions involve what 2 things?
1) Making and breaking chemical bonds. 2) Rearrangement of atoms.
What reactants are required to have an Acid/Base chemical reaction?
1) an acid 2) a base
What two chemical substances are produced in combustion?
1) water 2) carbon dioxide
How many chemical substances are produced in combustion?
2
In a double displacement chemical reaction, how many molecules switch places?
2
In a synthesis reaction, how many reactants are required?
2 or more
What is always formed in an Acid/Base chemical reaction?
water
How many types of chemical reactions are there?
6
Describe a general synthesis reaction using the letters A and B:
A + B -> AB
Describe a single displacement chemical reaction using A, B, & C
A + BC -> AC + B
What is a chemical reaction?
A process in which one set of chemical substances (reactants) is converted into another (products).
Describe a displacement chemical reaction using A, B, C, & D
AB + CD -> AD + CB
Describe a decomposition chemical reaction using the letters A and B.
AB -> A + B
When an acid and a base are the reactants in a chemical reaction, what type of chemical reaction is it?
Acid/Base
How are chemical reactions represented?
BALANCED CHEMICAL EQUATIONS
In a chemical reaction equation, how are the reactants and products represented?
CHEMICAL FORMULAS

What type of chemical reaction do you have when a complex molecule breaks down to make simpler ones?
Decomposition
What type of chemical reaction do you have when the anions and cations of two different molecules switch places?
Double displacement
Describe an Acid/Base chemical reaction using A, B, H, & O
HA + BOH -> H₂O + BA
If a precipitate is produced in a chemical reaction, what is that called? (hint: it is NOT one of the six types of chemical reactions)
Precipitation reaction
What are the products in a decomposition chemical reaction?
Simpler molecules
What chemical reaction is the opposite of a decomposition reaction?
Synthesis
What is the reactant in a decomposition chemical reaction?
a complex molecule
In a chemical reaction, if one of the products is a solid (insoluble), what is that solid (insoluble) called?
a precipitate
What type of chemical reaction is this: NH₄OH + HBr → H₂O + NH₄Br
acid/base
What type of chemical reaction is this: CH₄ + 2 O₂ → CO₂ + 2 H₂O
