Question

Please Check. thanks :)
b. Determine oxidation states and answer the following questions about the reaction 2Li + 2H2O 2LiOH + H2. (1 point)
Oxidation state of Li in reactant: 0
In product: +1
Oxidation state of H in reactant: 0
In product: +1
Oxidation state of O in reactant: -2
In product: -2

What type of reaction is this? Is it also a redox reaction? If so, what was oxidized and what was reduced?
This is an example of a displacement reaction since the lithium replaced the hydrogen. However, it is not a redox reaction because the hydrogen was not completely reduced.

Answer 1

H went from -1 to 0 (recall homonuclear diatomic molecules (molecules of the same type of atom) are 0).

Answer 2

i meant +1 to 0

Answer 3

oh whoops. thanks for catching that

Answer 4

no problem!
