In order to determine the calories in a food sample, a chemist prepares their calorimeter with 100ml of water. The chemist took an initial temperature of 22 degrees celsius. After the food source burned the chemist then determined the the final temperature was 42 degrees celsius. What was the change of temperature of the water?

c. is the answer

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 would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
