Avolume of 24.72±0.06 ml of hno3 solution was required for complete reaction with 0.8359±0.0007 g of na2co3, (fm 105.988±0.001 g/mol ). find the molarity of the hno3 solution and its absolute uncertainty.

i just learnt this recently but i need to look through my notes again

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

sure im new too!

explanation:

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.
