Na (sodium) has a valence of 1+ and oxygen (O) has a valence of 2-, so it will take 2 Na for each O. The compound formed (sodium oxide) has the formula Na2O.
Sodium Oxide
The sodium oxide is Na2O.

2H - C - H + NaOH ------> H- C - O -Na + CH3 - OH
+1 for Na, +1 for H, -2 for each O, +4 for S
This formula is BeO.

It depends on the compound. Water, H2O, contains the elements hydrogen, H, and oxygen, O; and sodium nitrate, NaNO3, contains the elements sodium, Na, nitrogen, N, and oxygen, O.
Find moles. 365 grams Na (1 mole Na/22.99 grams) = 15.876 moles Na ======================================================================= Now, sodium and nitrogen are about one to one, so they will be 1 in the empirical formula and either can be the divisor of oxygen's mole number 47 mole O/15.774 mole N = 2.979 moles oxygen ----------------------------------we call this 3 NaNO3 -----------the empirical formula of the compound ( sodium nitrate )
2H - C - H + NaOH ------> H- C - O -Na + CH3 - OH
+1 for Na, +1 for H, -2 for each O, +4 for S
This formula is BeO.

It is a pure compound, not a mixture at all.

no it's 0. Na = +1 O = -2 Na2O = +1(2) + (-2) = 0
We know that sodium hydroxide is a chemical compound. It is comprised of an atom of sodium (Na), and atom of oxygen (O), and an atom of hydrogen (H). It's chemical formula is NaOH.
NaOCl is a compound because it is composed of three elements. If it's not on the periodic table, then it's not an element. Na, O, and Cl are on the periodic table, so they are elements. When they combine, they form compounds.
