Types of Reactions

Question 1

Chemical equation

Answer 1

Shows information about a chemical reaction

Question 2

A balanced equation

Answer 2

A chemical equation where the number of each atom is the same on each side

Question 3

Synthesis

Answer 3

Two compound or element combine to form a compound
A + B -> AB

Question 4

Specific synthesis reactions

Answer 4

Metal oxide + water -> a base (metal hydroxide)
Non metal oxide + water -> an acid

Question 5

Decomposition

Answer 5

A compound decomposing into its elements
AB-> A + B

Question 6

Specific decomposition

Answer 6

Metal carbonate -> metal oxide + carbon dioxide
Metal nitrate -> metal nitrite + oxide
Metal hydroxide -> metal oxide + water

Question 7

Combustion

Answer 7

A reaction of a substance with oxygen to produce an oxide and heat or light

Question 8

Single displacement

Answer 8

Where a metal or non metal replace an element in a compound (the replacing metal has to be higher on the reactivity scale)

Ax+y -> Ay + x

Question 9

Specific single displacement reactions

Answer 9

Metal replaces hydrogen in acid
Metal replaces hydrogen in water (calcium and above on reactivity scale)
