  1. The ability to smell hydrogen cyanide (HCN) is a genetically determined trait, absent in 20% to 40% of the population. It is thought that the ability to smell this chemical is recessive.

  1. Which letter would you use to represent a “HCN smeller”?____

  1. Which letter for a “HCN Non-smeller”?_____

            A man who is a HCN smeller marries a woman who is heterozygous

for the trait, and they have kids. (a punnett square may help)

  1. What genotypes and in what ratio do you expect to see in the offspring?

  1. What phenotypes and in what ratio do you expect to see in the offspring?

  1. What is the probability of the parents having a child who can smell HCN?

Hydrogen cyanide, HCN, is a poisonous gas. The lethal dose is approximately 300. mg HCN per kilogram of air when inhaled. The density of air at 26 ∘C is 0.00118 g/cm3.HCN forms when synthetic fibers containing Orlon® or Acrilan® burn. Acrilan® has an empirical formula of CH2CHCN, so HCN is 50.9% of the formula by mass. A rug in the laboratory measures 12.0× 15.0 ft and contains 30.0 oz of Acrilan® fibers per square yard of carpet. If the rug...

Hydrogen Cyanide (HCN), an important reactant for the synthesis of numerous products, is produced catalytically from methane, ammonia, and oxygen in the following reversible reaction: CH4 + NH3 + 3/2O2 ------> HCN + 3H2O A continuous reactor is designed to produce HCN at 2 kmol/min. Air is fed continuously to supply the oxygen (O2), so nitrogen is present as an inert. The oxygen is the limiting reactant and the ammonia (NH3) and methane (CH4) are fed at a 20% and...
