1. A 100 kg person is getting ready to jump out of a plane. Use the
conservation of energy equation to
explain how much KE and PE they
possess before jumping from their
initial height of 5,000 m and how
much they possess after falling to a
height of 2,000 m. (Assume this is an
ideal system where total energy is
constant)

i'm pretty sure its b i might be wrong though!

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
