Chemical Reactions Flashcards
1
Q
Synthesis
A
two or more substances combine to form one new substance e.g. A + B = AB
2
Q
Decomposition
A
a substance breaks down into two or more simple substances e.g. AB = A + B
3
Q
Single Displacement
A
a more reactive element replaces a less reactive e.g. A + BC = AC + B
4
Q
Double Displacement
A
two elements from two different compounds swap places e.g. AB + CD = CB + AD
5
Q
Acid Base
A
an acid and base reactive to form salt and water
6
Q
Combustion of Hydrocarbons
A
a hydrocarbon (fuel) in the presence of oxygen breaks down into carbon dioxide and water.
7
Q
Combustion of Metals
A
some metals burn in oxygen to produce metal oxides.
