The wet cotton traps any HBr that escapes the reaction mixture. The trapping reaction is simply what happens when HBr dissolves in water, but it is still an acid/base reaction that is in principle reversible. Complete the acid/base equilibrium started for you below, draw the curved arrow pushing in BOTH directions and identify the stronger and weaker Bronsted acid and base on each side of the equilibrium.

Explanation:

find the solution below

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

thats how its supposed to be
