Consider this system at equilibrium: 2CO(g) + O2(g) 2CO2(g) + heat

Which of the following stresses would cause this system to shift to the left in response.

(A) removing some CO2
(B) lowering the temperature of the system
(C) adding some O2
(D) adding some CO
(E) removing some O2

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.

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.
