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...
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.
ZnFl2. The '2' is a subscript though.
The alkali metal would have a subscript of +1 while the nonmetal from group 6A would have a subscript of -2 to balance charges.
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.
Sodium - 6 phosphorus - 2 oxygen - 8
Not completely sure, but it's an ionic bond so I'm sure it would be lead (II) nitride
Copper(II) chloride
The correct name for the compound N₂O₅ is dinitrogen pentoxide.
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.
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 )
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 2 is called a Subscript.
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]
Ammonium Dichromate: (NH4)2Cr2O7. The subscript on Ammonium (NH4) is 2.
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.
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.
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.
