What are elements in a compound from its formula?
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.
What is the emperical formula of a compound containing 365g of Na 221g of N and 752g of 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 )

Does the compound Na2O contain a 3 plus charge?
no it's 0. Na = +1 O = -2 Na2O = +1(2) + (-2) = 0
Is sodium hydroxide an element or compound?
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.
Is NaHO a element or compound?
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.
