Metals exhibit
due to the mobility of valence electrons.
a)
brittleness
b)
high conductivity
o
low melting point
d)
high solubility in water

B

Explanation:

This is because conductivity depends on the mobility of electrons.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
