You have the mythical metal element “X” that can exist as X+
, X2+, and X5+ ions. (2pts.)
a) What would be the chemical formula for compounds formed from the
combination of each of the X ions and SO4
2-
?
b) If the name of the element X is exy, what would be the names of each of the
compounds from part of this problem?
a) X+ and SO4 2- would form XSO4, X2+ and SO4 2- would form X2SO4, and X5+ and SO4 2- would form X5SO4.
b) The names of the compounds would be Exy sulfate, Exy2 sulfate, and Exy5 sulfate.
a) The chemical formula for compounds formed from the combination of each of the X ions and SO4^2- would be:
- X+ and SO4^2- would form XSO4
- X2+ and SO4^2- would form X(SO4)2
- X5+ and SO4^2- would form X(SO4)5
b) If the name of the element X is exy, the names of each of the compounds would be:
- For X+ and SO4^2-, the compound would be named exy sulfate.
- For X2+ and SO4^2-, the compound would be named exy bisulfate.
- For X5+ and SO4^2-, the compound would be named exy pentasulfate.
To find the chemical formula for compounds formed from the combination of each of the X ions and SO4^2-, we need to consider the charges of the ions involved.
a) For X+, we know that the sulfate ion (SO4^2-) has a charge of 2-. Therefore, to balance the charges, we need two X+ ions to combine with one SO4^2- ion. The chemical formula for this compound would be (X+)2(SO4^2-).
For X2+, we use the same logic. Since SO4^2- has a charge of 2-, we only need one X2+ ion to combine with one SO4^2- ion. The chemical formula for this compound would be X2+(SO4^2-).
For X5+, we once again consider the charge of the sulfate ion. To balance the charges, we need five X5+ ions to combine with one SO4^2- ion. The chemical formula for this compound would be (X5+)5(SO4^2-).
b) If the name of the element X is exy, we can determine the names of the compounds using the charges of the ions involved.
For (X+)2(SO4^2-), the name would be exy sulfate.
For X2+(SO4^2-), the name would be exy sulfate.
For (X5+)5(SO4^2-), the name would be exy sulfate.
Note: The name of the compound remains the same regardless of the charge of the metal ion X.
