2Al(s) + 3Br2(l) → 2AlBr3(s) ΔSo is equal to -144 J K-1Use this value and data from Appendix A of Blackman to calculate the value of So for solid aluminium bromide (in J K-1 mol-1)
I would go at it from the inside, the siding is nailed starting at the bottom and would have to be removed from the top down, or you could wait a few years until the nails wear through and it will blow down like mine is doing at my money pit, I mean HOME.
take a screwdriver and start at a joint and carefully get the tip of the screwdriver under the lap of the siding then pull it along and the siding will separate you won't have to remove it it will raise up enough for you to blow in the insulationit will pop back together the same way good luckif you bend the tip of the screw driver at about 60 degree this will help.
This Site Might Help YouRE: How do I remove aluminum siding to insulate my home? I want to remove the top strips and under the windows and blow insulation into the sidewallsThere are no firestops in the walls, so I shouldn't have to take off more than the top and under the windowsHow do I do this? The siding is 8quot; wide.
Removing aluminum siding is no easy job when you plan to reuse it and when you plan to remove it from other than the top downRemember the siding interlocks as it is installed from the bottom up and this makes it very difficult to remove Although you do not have fire stops, you do have wiring in the walls and this will impede the flow of blown in insulationWhether you are working from the inside or outside you will need a hole between each pair of wall studs - that is a lot of holes If you do this job it is IMPORTANT, when reinstalling the aluminum, to remember to place the nails in the center of each slotAluminum expands and contracts greatly, especially on south facing walls and if nails are place in holes or at the edge of slots the siding will buckle as it heats and cools during any day Finally, I have a 35 year old poorly insulated house in an area where we get winterI replaced my windows with low e argon filled vinyl windows - the insulating properties during both the heating and air conditioning seasons are remarkable.
I don't have access to you data at data from Appendix A of Blackman so you may need to use your data, if it varies from the data obtained from; bilbo.chm.uri.edu/CHM112/tables/tstandard entropy of Al(s) 28.3 J/mol-K standard entropy of Br2(l) 152.23 J/mol-K ΔSo S products - reactants ΔSo [(2) (S of AlBr3(s)] - [(2) (28.3) (3) (152.23)] -144 J K-1 [(2) (S of AlBr3(s)] - [(56.6) (456.69)] -144 J K-1 [(2) (S of AlBr3(s)] - (513.29) -144 + 513.29 [(2) (S of AlBr3(s)] 2 S of AlBr3(s) 369.29 S of AlBr3(s) 184.645 your answer, rounded to 1's decimal place would be So for solid aluminium bromide 185 J K-1 mol-1
