Answer:B. The sodium ion has a smaller radius than the atom.
Explanation:
Because size of cation is less than neutral atom
we have
work done (W)= force(F) × displacemen(s)
or, 80= F× 8
or, F= 10 N
therefore, 10 N force is required to lift the rock.
True. Refer to the heat equation of water
Increase: volume, pressure, kinetic energy, gas particle collisions
Stays the same: number of moles of gas
I think it was D. Hopefully I’m right
