ziro4ka [17]
The answer is - ide.

That is how you name the anions in a ionic compound, you replace the ending of the name of the element with ide.

Some examples:

Ionic compound            anion            name of the anion

NaCl                                Cl-                 chloride

KF                                    F-                  fluoride

NaI                                   I-                    iodide

CaBr2                              Br-                 bromide

Sulfuric acid (H2SO4) is prepared commercially from elemental sulfur using the contact process. In a typical sequence of reactio
Elan Coil [88]
I believe the end result is still 83 moles since there is never an amount of sulfur atoms added to the initial amount, but rather oxygen and water is repeatedly added to it. To find it's weight, first find the molar mass of H2SO4:

H2 + S + O4 = 2.00 + 32.1 + 64.0 = 98.1 g/mol

and mass = (98.1 g/mol)(83 mol) = 8142.3 g

rounded to 8.1 x 10^3 g assuming 100% yield?
