Which of the following rules is a HIPAA rule that requires healthcare organizations to maintain policies and procedures for confidentiality?
privacy rule
security rule
confidential rule
provider rule

its first and third is your answer i did the qustion the fourth isnt right

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.

50.23 i believe is correct but don't quote me on that.
