Sulfur has four naturally occurring isotopes: Sulfur – 32, Sulfur – 33, Sulfur – 34, Sulfur – 36. What is the atomic mass of sulfur if 95.00% of sulfur atoms have a mass of 31.972 amu, 0.76% have a mass of 32.971 amu, 4.22% have a mass of 33.967 amu, and 0.01% have a mass of 35.967? Answers; 35.967 amu

33.75 amu

32.971 amu

32.06 amu

c is the answer because when something is left after something evaporates that shows the chemical change.

explanation:

the marks go by 4s

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.
