Lithium and oxygen react to form lithium oxide. what is the balanced equation for this reaction?
oa
2li + o2 → lizo
ob. li + o2 . lizo
oc 4li + o2 2l120
.
od. 2li + 202 – 4lizo
x

C

Explanation:

Both lithium and oxygen react to form an ionic bond between them. There is one Oxygen atom on the right side and 2 Oxygen atoms on the left, therefore coefficient 2 is added on right side to balance the oxygen atoms. 

Li + O2 --> 2 Li2O 

There will be 4 Lithium atoms on right side and 1 Lithium on the left therefore coefficient  4 is added to balance the lithium atoms

4 Li + O2 --> 2 Li2O 

The balanced equation is: 

4 Li + O2 --> 2 Li2O

what? are the statements?
