Lecture 1

Question 1

alkali/alkaline metals

Answer 1

give up outer valence electrons

Question 2

transition metals

Answer 2

uses d orbitals for bonding

Question 3

main group elements

Answer 3

uses s and p orbitals for bonding

Question 4

lanthanides/actinides

Answer 4

have filled/partially-filled f orbitals

Question 5

organic chemistry vs. inorgranic chemistry

Answer 5

• organic chemistry is the chemistry of compounds with carbon bonding to C, H, N, O, P, S, Cl, Br, and I
• inorganic chemistry is the chemistry of everything else, therefore it applies to many areas
• concepts and principles organic and inorganic chemistry overlap

Question 6

catalyst

Answer 6

• converts the reactant into a product and emerges unchanged
• recycling on a molecular level
• ultimate manifestation of Green Chemistry

Question 7

perfect reaction

Answer 7

• reactants forming 100% pure product at desired amount and time
• no separation
• no waste
• no effect on environment

Question 8

steam reforming

Answer 8

• converts strong greenhouse gas (methane) into hydrogen
• carbon dioxide is a byproduct
• cheapest method to produce hydrogen

Question 9

Haber-Bosch (Mittasch) Process

Answer 9

• converts hydrogen into ammonia
• ammonia is used in fertilizer
• 500 million tons of fertilizer per year (low amount)
• 30-50% of world’s population is sustained by it

Question 10

penicillin mass production

Answer 10

• penicillin made from fermentation

- useful for soldiers at way to prevent infection rate increasing survival rate

Question 11

geological sequestration of carbon dioxide

Answer 11

• used to reduce carbon dioxide in the air from steam reforming
• one of the largest “blue hydrogen” facilities is outside of Edmonton, ran by Air Products
• carbon dioxide is pumped to a depleted oil and gas wells and permanently sequesters it
