Title: What is the major drawback to using bituminous coal as an energy source?
Post by: dmcintosh on Nov 18, 2019

Question 1

Determine the number of vertices and faces in the closo-Borane B12H122-.
◦ vertices = 8, faces = 12
◦ vertices = 6, faces = 8
◦ vertices = 8, faces = 16
◦ vertices = 12, faces = 24
◦ vertices = 12, faces = 20

Question 2

What is the major drawback to using bituminous coal as an energy source?
◦ It has an extremely high surface area, which makes it difficult to burn.
◦ It contains a high amount of sulfur, which when burned contributes to acid rain.
◦ It has very low carbon content.
◦ Bituminous coal is noncrystalline, which gives it a low energy/gram ratio.
◦ Bituminous coal is very expensive to produce and transport.
