7. The most likely to conduct electricity is CdLi because it has free electrons

Question

7. The most likely to conduct electricity is CdLi because it has free electrons whereas other have no free electrons or have a lone pair.. option C is correct

8. Magnesium react with nitrogen to form magnesium nitride

Option E is correct

9 . Option A is false .

The density of gas is not constant as long as it's temperature remain constant

10. Option A is correct ..each flask has same number of molecules.

Velocity and density depend upon molecular mass which is different for different molecules .
