Question

How can I identify a type of reaction just by looking at the chemical equation?

Answer 1

Attached are a few examples I'm working with.

Answer 2

Reactions of the type A+B-> AB are combination reactions.
Reactions of the type AB+C-> AC+B are single displacement reaction.
Reactions of the type AB+CD-> AC+BD are double displacement reactions.
Reactions like AB-> A+B are decomposition reactions.

Answer 3

Yeah, but I still don't quite understand how to use that when dealing with chemical equations.

Answer 4

Given any compound can you identify the ions in the compound?
