4Na + O2 —> 2Na2O
In this chemical reaction, how many moles of Na2O will be produced if 2.90 moles of Na react completely? Express answer to three significant figures.

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
