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.
What is the formula of zinc flouride?
ZnFl2. The '2' is a subscript though.
What subscripts would most likely be used if an alkali metal and a nonmetal from group 6A formed an ionic compound?
The alkali metal would have a subscript of +1 while the nonmetal from group 6A would have a subscript of -2 to balance charges.
What does a subscript tell us in a binary nonmetal compound?
In a binary nonmetal compound, a subscript tells us the ratio of atoms present in the compound. Each subscript represents the number of atoms of that element in the compound. For example, in CO2, the subscript 2 indicates that there are two oxygen atoms for each carbon atom.
How many atoms of each elements make up 2Na3PO4?
Sodium - 6 phosphorus - 2 oxygen - 8
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 name for CuCl subscript 2?
Copper(II) chloride
What is the correct name for the compound N subscript 2 and O subscript 5?
The correct name for the compound N₂O₅ is dinitrogen pentoxide.
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 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.
What is the 2 in H2O called?
The 2 is called a Subscript.
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]
What is the subscript for ammonium in the chemical formula ammonium dichromate?
Ammonium Dichromate: (NH4)2Cr2O7. The subscript on Ammonium (NH4) is 2.
How does Na Br2--NaBr balance?
Na + Br ₂→ NaBr This happens because: When certain diatomic elements (Br, I, N, Cl, H, O, F) are alone you add a 2 as a subscript so they are (Br₂, I,₂ N₂, Cl₂, H₂, O₂, F₂). But when you cross Na (which has a charge of +1) with Br (which has a charge of -1) They cancel and you get NaBr. Na + Br ₂→ NaBr This happens because: When certain diatomic elements (Br, I, N, Cl, H, O, F) are alone you add a 2 as a subscript so they are (Br₂, I,₂ N₂, Cl₂, H₂, O₂, F₂). But when you cross Na (which has a charge of +1) with Br (which has a charge of -1) They cancel and you get NaBr.
Where does the 2 in Co2 go- Above the O or beneath it?
The 2 in CO2 is typically written as a subscript and goes below the O. This notation helps indicate that there are two oxygen atoms bonded to the carbon atom in carbon dioxide.
What is the balanced equation when magnesium reacts with oxygen?
2Mg + O2 = 2MgO Explanation :- Mg has a charge of 2 + O has a charge of 2- O can only exist as O2 in nature, so, the subscript 2 is added to the element. The 2 charges cancel each other out, leaving the product with no subscript at all.
