Types of chemical reactions Flashcards
What are the five types of Chemical reactions
- synthesis
- Combustion
- Decomposition
- Single displacement
- Double displacement
Synthesis Reaction
they involve the combination of smaller atoms or molecules, to form a new larger compound
Simple broken down –> complex
Name an example of a synthesis reaction
The formation of table salt (sodium Chloride)
Decomposition
It involves a larger compound being split into atoms, or smaller molecules
(More comples–> simpler)
-Opposite of synthesis
Name an example of a decomposition reaction
The decomposition of Copper (II) carbonate
Decomposition exceptions
- When you are dealing with Oxyanion compounds, many of them decompose to oxygen gas
- Carbonates DO NOT decompose into elements; produces carbon dioxide, and a metal Oxide
Single dispalcement
The reaction between a element and a ionic compound. The element will either switch with one element apart of the ionic compound
What happens when H2O splits into 2 ions
It splits into H+, and OH-
What is an example of a single displacement reaction
Zinc and hydrogen chloride
What are single displacement reactions dependent on?
They are dependent on the activity series, because we have to check if one element is more reactive than the other
What is the activity series
It is used to predict the outcome of single displacement reactions
Double displacement
A double displacement reaction occurs when you have two ionic compounds for the products, as for the end results of the products, the cations of both compounds switch and attach themselves to a different anion
For double displacement reactions we use a

What do chlorates decompose into
They decompose to oxygen gas and a metal chloride
What do carbonates decompose into
Carbon dioxide and a metal oxide
