Types of Chemical Reactions

Question 1

What is combustion?

Answer 1

A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide

Question 2

Synthesis

Answer 2

A synthesis reaction is when two or more simple compounds combine to form a more complicated one.

Question 3

Decomposition

Answer 3

A decomposition reaction is the opposite of a synthesis reaction - a complex molecule breaks down to make simpler one

Question 4

Single displacement

Answer 4

This is when one element trades places with another element in a compound

Question 5

Double displacement

Answer 5

This is when the anions and cations of two different molecules switch places, forming two entirely different compounds

Question 6

Neutralization

Answer 6

A special kind of double displacement reaction that takes place when an acid and base react with each other

Question 7

What is the law of conservation of mass?

Answer 7

The masses of reactants of products in a given reaction are always the same
