As you go across a period, radius shrinks because you are adding protons. The added positive charge increases pull on the electron shells.
As you go down a group, radius gets larger because you are increasing shells of electrons. This increases shielding of the nucleus' positive charge, so the electrons are not pulled in as much.
Ever seen a waterfall ? what do you think happens when all that water slams into the ground below ? same as when you turn a hosepipe on a flowerbed.
also, there's hydraulic cracking where water gets into cracks and freezes, splitting rocks apart.
fast moving water can carry sediment and roll rocks along the bottom. if the water slows down, it drops the rocks and heavier sediment. if it floods a field, say, then drains away, the grass will also filter smaller particles out, or the water might evaporate and leave fine sediment behind.
Answer:
Gasoline is burning
Explanation:
examples of chemical changes are burning , cooking,rusting and rotting
Yes its True. If we consider the electronegativity difference of Carbon and Bromine it is,
E.N of Bromine = 2.96
E.N of Carbon = 2.55
_________
E.N difference = 0.41
As the E.N difference is greater than 0.4 so this bond is slightly polar. And Bromine more electronegative than carbon will attract the electrons density towards itself making carbon partial positive, and itself partial negative.
