1.	CO_(3)O_(4) is an oxide of Ca (III) and Cu (II) .If its formula is CO_(x)(II)CO_(y)(II)O_(4) , then what is the value of x and y ?
Answer» SOLUTION :The SUM of oxidaiton number of the elements in a compound is equal to ZERO `CO_(x)(II)CO_(y)(II)O_(4)`,2x+3y -4xx2=0 or, 2x+3y=9 The only solution for this EQUATION is x=1 and y=2.
