58:00 The table describes how some substances were formed. Substance Description P Formed by boiling pure water Q Formed by combining three hydrogen atoms to every nitrogen atom R Formed by adding 5 g of sugar to 1 L of water S Formed by compressing carbon under high pressure Based on the given descriptions, which substance is most likely a mixture? P Q R S

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.

the correct answer to this question is 2
