M(CO)(x)(NO)(y) underset(-CO)overset(+N...

`M(CO)_(x)(NO)_(y) underset(-CO)overset(+NO) to M(NO)_z`
Where EAN of metal (M) in both produce and reactant is samme and it is 54. then calculate value of (x+y=-z). (where x,y and z are netural numbers and M belong to 6th group according to long form of periodic table)

Text Solution

Verified by Experts

The correct Answer is:
1
Metal `(M) impliesMo(z=42)`
`Mo(CO)_(x)(NO)_(y) underset(-co)overset(+NO) to Mo(NO)_(z)`
if y=2, then x=3 and z=4, hence x=y-z=3+2-4=1
