6.3 Types Of Chemical Reactions

Question 1

Synthesis

Answer 1

AKA combination. 2+ substances (usually elements) combine to form a compound
A + B = AB

Question 2

Decomposition

Answer 2

1 substance breaks up into 2+ substances
AB = A + B

Question 3

Single Replacement

Answer 3

An element and a compound react to form a new element and a new compound. One element displaces another.
A + BC = B + AC
or
A + BC = C + BA

Question 4

Double Replacement

Answer 4

2 compounds reacting to form 2 new compounds. R generally ionic and take place in water.
AB + CD = AD + CB

Question 5

Combustion

Answer 5

Usually has a fuel combining rapidly w/ oxygen from air. Produces water and carbon dioxide.
Hydrocarbon + oxygen = water + carbon dioxide

Question 6

Neutralization

Answer 6

When an acid and a base react to form a salt and water.
