Question

The elements lithium and oxygen react ex- plosively to from lithium oxide (Li2O). How much lithium oxide will form if 3.35 mol of lithium react?

Answer 1

Step-by-step explanation:

The balanced chemical equation for the reaction between lithium and oxygen to form lithium oxide is:

2 Li + O2 -> Li2O

So, for every 1 mol of lithium that reacts, 1 mol of lithium oxide will be formed. Therefore, if 3.35 mol of lithium reacts, 3.35 mol of lithium oxide will be formed.
