Na(s) +2 H2O (l) ➔ 2NaOH (aq) + H2 (g) Suppose that 10.0 g of sodium reacts completely with 1.00 L of water and the final solution volume is 1.00L. What is the molarity of the NaOH solution formed by this reaction?

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
