Na2 SO4? - SO4 is a polyatomic ion with a charge of -2. It is Sulfate. When you have a polyatomic after the first element, you do nothing to change the ending of the polyatomic ion. Since Na has an oxidation number of +1, Na2 creates a +2 which balances out with the -2 of sulfate. So, the name would be Sodium Sulfate. (Again, you do nothing with the ending of a Polyatomic | don't add an -ide at the end.
Sodium Sulfate... (oh, and here's a helpful hint: if you havent already noticed, I believe that any compond with more than two elements will have a polyatomic ion. The polyatomic should be the symbols right after the first element, in this case Na - soduim...

Does the 2 mean How many hydrogen atoms are in a molecule of water?
Yes. In the chemical formula H2O, the subscript 2 after the hydrogen means there are two hydrogen atoms in a molecule of water. The absence of a subscript after the oxygen means the subscript is understood to be 1, so there is one atom of oxygen in a water molecule.
The elements that make up a compound and the exact number of atoms of each element in a unit of the compound can be?
Subscript (:This is a subscript: (Na2) the "2" is the Subscript.
How many atoms of each elements make up 2Na3PO4?
Sodium - 6 phosphorus - 2 oxygen - 8
What is the formula of zinc flouride?
ZnFl2. The '2' is a subscript though.
How many moles of Na are there in 5 moles NaCl?
There are 5 formula masses of Na in 5 formula masses of NaCl, as indicated by the fact that the symbol for sodium has no explicit subscript in the formula of NaCl. Neither sodium nor sodium chloride has moles in the strictest sense, since neither of them is covalently bonded.
What is the name for Pb subscript 3 N subscript 2?
Not completely sure, but it's an ionic bond so I'm sure it would be lead (II) nitride
What is the correct name for the compound N subscript 2 and O subscript 5?
dinitrogen pentoxide N2O5
What is the formula for the 5 following compounds potassium bromide iron III sulfate copper II chloride tetraphosphorus heptanitride ammonium carbonate?
potassium bromide - KBr iron (III) sulfate - Fe[subscript 2](SO[subscript 4])[subscript 3] copper (II) chloride - CuCl[subscript 2] tetraphosphorous heptanitride - P[subscript 4]N[subscript 7] ammonium carbonate - (NH[subscript 4])CO[subscript 3]
How do you do the crossover method for calcium hydride?
The calcium ion is Ca2+ and the hydride ion is H-. So, the subscript for the Ca is 1 and the subscript for H is 2. The formula unit is CaH2. The subscript 1 for Ca is not written. When there is no subscript it is understood to be 1.
Where does the 2 in Co2 go- Above the O or beneath it?
It is a subscript, so it goes below.
How do you prime factorise 20 and give your answer in subscript form?
Factor out each prime by prime to obtain: 4 x 5 = 2 x 2 x 5 So the answer is 2² x 5 * * * * * and the word is "superscript", not subscript.
What is the subscript of oxygen dichloride?
The chemical formula of dichlorine monoxide is Cl2O - 2 is a subscript.
What does the subscript three mean in NaHCO3?
The 3 oxygen atoms in the carbonate radical ( -2 CO3 ).Sodium bicarbonate ( NaHCO3 ) is composed of three radicals:sodium ( Na+ )hydrogen ( H+ )carbonate ( -2 CO3 )
Does the 2 mean How many hydrogen atoms are in a molecule of water?
Yes. In the chemical formula H2O, the subscript 2 after the hydrogen means there are two hydrogen atoms in a molecule of water. The absence of a subscript after the oxygen means the subscript is understood to be 1, so there is one atom of oxygen in a water molecule.
The elements that make up a compound and the exact number of atoms of each element in a unit of the compound can be?
Subscript (:This is a subscript: (Na2) the "2" is the Subscript.
Nitric oxide gas reacts with hydrogen gas to form ammonia gas and water vapor?
2NO+5H(subscript 2)----->2NH(subscript 3)+2H(subscript 2)O
What is the subscript on chlorine if calcium and chlorine are combined?
