2.5 moles of oxygen are required
Answer:
solution given:
the reaction is:
[tex]4Na +O_2\rightarrow2 Na_2O[/tex]
it shows that
4 moles of sodium reacts with 1 mole of oxygen to produce 2 mole of sodium oxide.
so
10 moles of sodium reacts with [tex]\frac{1}{4}*10=\frac{5}{2}=2.5[/tex] moles oxygen to produce [tex]\frac{2}{4}*10=5[/tex] mole of sodium oxide.
