The oxidation states of transition metal atoms in and
, respectively are X, Y and Z , the sum of X, Y and Z is ___________
Answers (1)
In K2Cr2O7, Cr is in +6, thus, x = 6
In KMnO4, Mn is in +7, thus, y = 7
In K2FeO4, Fe is in +6, thus, z = 6
Thus, we have:
x + y + z = 6 + 7 + 6 = 19
Therefore, the correct answer is 19.
