How many moles of lithium oxide will form if 2.0 moles of lithium reacts?
li + o2 → li2o

1 mole Li2O

Explanation: Solution attached

First balance the given chemical equation

4 Li + O2 => 2 Li2O

The stoichiometric factor of Li and Li2O is 4 moles Li and 2 moles Li2O

Solution:

2 moles Li x 2 moles Li2O / 4 moles Li

= 1 mole Li2O

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)

You would do 1500/4 and the answer is 375
