Consider the following system at equilibrium. S(s) + O2(g) ---> SO2(g)
a) How will adding more S(s) shift the equilibrium? ( to the right , left or no effect )
b) How will removing some SO2(g) shift the equilibrium? ( to the right, left, or no effect )
c) How will decreasing the volume of the container shift the equilibrium? ( to the right , left or no effect )

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
