34.1 grams of ethene (C2H4) burns in the presence of 28.8 grams oxygen, what is the limiting reactant?

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

< 3

how to make a simple air condition

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.
