Clarissa is conducting an experiment. She carefully measures out 15g of baking soda into a bag. She then carefully measures out 25ml of vinegar (which is equal to 25g), pours the vinegar into the bag and immediately seals it. She then watches bubbles start to form and the bag fills up with gas. According to the law of conservation of mass, how much should the bag weigh after the reaction is finished? 10g
40g
25g
15g

he would use the colour black

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.
