If you start with 17.2 g of Al2(SO3)3 and you produce 6.83 gAl(OH)3, what is your percent yield for this reaction?

Al2(SO3)3 + 6 NaOH → 3 Na2SO3 + 2 Al(OH)3

Explanation:

Hello,

In this case, since the aluminum sulfite, whose molar mass is 294.153 g/mol, is in a 1:2 molar ratio with aluminum hydroxide, whose molar mass is 78 g/mol, we can perform the following stoichiometric procedure to compute the theoretical yield of aluminum hydroxide to furtherly compute the percent yield:

So we compute the percent yield considering the actual yield is 6.83 g:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
