When a reaction loses more energy than it absorbs, the reaction is considered?

absorbtion reactions is when a chemical reaction releases more energy than it absorbs and you can also see them die on the inside. reletion reactions is when a chemical reaction absorbs more energy than it releases. You are already familiar with enthalpy: melting ice is endothermic and freezing water is exothermic.

Explanation:

i think its 100

i hope this !

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.
