Question 2

What is a Displacement Reaction

Answer 2

This is a reaction in which the more reactive element will displace the less reactive element from its compound and replace it.

Question 3

What is oxidation

Answer 3

This is when a substance gains oxygen

Question 4

What is reduction

Answer 4

This is when a substance loses oxygen

Question 5

What is a reducing agent

Answer 5

This is a substance that reduces some other substance by giving electrons to the other substance. These agents give away electrons, so they are oxidized in the process.

Question 6

What is an oxidizing agent

Answer 6

This is a substance that oxidizes another substance by taking electrons away from the other substance and in turn, reducing itself by gaining those electrons.

Question 7
