The 5 different types of reactions
Whenever two or more substances combine to form a single product,
Example: When iron rusts, iron metal and oxygen gas combine to form one new substance, iron oxide.
A+B = AB
AB = A + B
Whenever a compound breaks down into two or more simpler substances, the reaction is called a decomposition reaction.
When hydrogen peroxide spontaneously decomposes, it becomes water and oxygen gas.
Single displacement reaction
A + BC -----> AC + B
Whenever one element takes the place of another, the reaction is called a single-displacement reaction.
will only occur if the more active metal will become part of
a compound in the product.
iron nail soaking in copper sulfate yields iron sulfate and copper.
AB + CD -----> AD + CB
Whenever two ionic compounds trade positively charged ions, the reaction is called a double-displacement reaction.
One of the products will either be water, a gas, or most commonly a precipitate (insoluble in water).
Burning methane (CH4) yields water and carbon dioxide.
The products will be water and carbon dioxide.
Whenever hydrocarbons combine rapidly with oxygen (usually by fire), the reaction is called a combustion reaction.
