Question 2: Redox Reactions (2 points) Unit 5
a. How can you tell if an element has been oxidized or reduced in a reaction? (1 point)

b. Determine oxidation states and answer the following questions about the reaction 2Li + 2H2O 2LiOH + H2. (1 point)

Oxidation state of Li in reactant:
In product:

Oxidation state of H in reactant:
In product:

Oxidation state of O in reactant:
In product:

What type of reaction is this? Is it also a redox reaction? If so, what was oxidized and what was reduced?
