Types of Reactions (slides)

Question 1

Five types of Chemical Reactions:

Answer 1

-Synthesis
-Decomposition
-Single Replacement
-Double Replacement
-Combustion

Question 2

Synthesis reaction:

Answer 2

two substances react to form a compound
A + B -> AB

Question 3

Decomposition Reactions:

Answer 3

a compound produce two simpler substances
AB -> A + B

Question 4

Decomposition reactions often require:

Answer 4

energy, heat, light, or electricity to occur

Question 5

Single Replacement Reactions:

Answer 5

one element replaces a similar element in a compound (ions switch places)
A + BC -> AC + B

Question 6

(Single Replacement Reactions) Cationic:

Answer 6

Metals switch places with other metals or hydrogen
A + BC -> AC + B

Question 7

(Single Replacement Reactions) Anionic:

Answer 7

nonmetals switch places with other nonmetals
A + BC - BA + C

Question 8

Double replacement reactions:

Answer 8

ions of 2 compounds in (aq) switch places to form two new compounds (double displacement)
AB + CD -> AD + CB

Question 9

(Double Replacement) Cations (+ions) always:

Answer 9

come first in an ionic compound

Question 10

Combustion Reactions:

Answer 10

substances react with oxygen releasing a large amnt of energy
Hydrocarbon + O2 -> CO2 + H2O

Question 11

(Combustion Reactions) Substances react with oxygen releasing:

Answer 11

large amnt of energy

Question 12

Combustion Reaction formula:

Answer 12

Hydrocarbon + O2 -> CO2 + H2O
