Types of chemical reactions Flashcards
(6 cards)
1
Q
What is combination/synthesis reaction
A
Two or more substances combine to form a single product e.g (C+O2 -> CO2)
2
Q
What is a decomposition reaction
A
A single compound breaks down into two or more simpler substances (1H2O->2H²+O²)
3
Q
What is a displacement (single replacement) reaction
A
One element replaces another in a compound E.G (Fe + CuSO4 -> Cu + FeSO4)
4
Q
What is a double displacement reaction
A
Two compounds exchange ions to form two new compounds e.g BaCl2 + Na2SO4 -> BaSO4 + 2NaCl
5
Q
What is a combustion reaction
A
A carbon containing compound reacts with oxygen to form CO2 and H20 e.g CH4 + 2O2 -> CO2 + 2H2O
6
Q
What is an acid based reaction
A
An acid reacts with a base to form salt and water e.g HCl + NaOH -> NaCl + H20
