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?

1 answer

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.
