We turn up a speaker so that it is 100 times as intense as before. How many decibels will it be if the original sound wave
is 90 decibels?
a 130 dB
b 100 dB
C 120 dB
d 90 dB
e 110 dB

a polar bond is formed when electrons are shared unevenly between atoms

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.

diaria maybe go see a doctor about that
