Sodium metal reacts violently with water to form NaOH and release hydrogen gas. Suppose that 10.0 g
of Na react completely with 1.00 L of water and the
final solution volume is 1.00 L.
1.What is the molar mass of NaOH?
2.Write a balanced equation for the reaction.
3.What is the molarity of the NaOH solution formed
by the reaction?

Water's surface tension and heat storage capacity are accounted for by its a) orbitals b) weight c) hydrogen bonds d) mass e) size
