A mixture of oxygen, carbon dioxide, and nitrogen, has a total pressure of 0.97atm. What is the partial
pressure of oxygen if the partial pressure of carbon dioxide is 0.70 atm and the partial pressure of
nitrogen is 0.12 atm? (report your with two significant digits).

iron and sleel

make siroeel

elements make up everything, and they combine to make compounds.

the answer is c

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.
