Posted by Jin on Thursday, July 15, 2010 at 2:17am.

How do you solve this problem?

In a certain industrial process involving a heterogeneous catalyst, the volume of the catalyst (in the shape of a shpere) is 10.0cm^3. Calculate hte surface area of the catalyst. IF the sphere is broken down into eight spheres, each having a volume of 1.25 cm^3, what is the total surface area of the spheres? Which of the two geometric configurations of the catalyst is more effective? (The surface area of a shpere is 4pir^2). Based on your analysis here, explain why it is sometimes dangerous to work in grain elevators?
