Answer:

The answer for the first problem is:  C₆N₁H₁₁O₁ or C₆NH₁₁O

Explanation:

Nylon composition:                     Mass        Divide by the atomic mass

Carbon                   63.68 %      63.68 g         63.68/ 12    = 5.3

Nitrogen                 12.38 %       12.38 g          12.38/14     = 0.88

Hydrogen                  9.8%           9.8 g           9.8/1           = 9.8

Oxygen                    14.14%         14.14 g          14.14/16      = 0.88

We choose the lowest number that is 0.88 for nitrogen and oxygen and divide the four results by this number

Carbon     5.3/0.88 = 6

Nitrogen    0.88/0.88 = 1

Hydrogen   9.8/0.88 = 11.1  = 11

Oxygen     0.88/ 0.88 = 1  

Then the empirical formula has this coefficients

        C₆N₁H₁₁O₁ or C₆NH₁₁O

Hemoglobin has a much greater affinity for carbon monoxide than oxygen. which principle explains why a hyperbaric chamber (conta
babunello [35]

Hemoglobin has a much greater affinity for carbon monoxide than oxygen. In a hyperbaric chamber (containing high levels of oxygen) can treat carbon monoxide poisoning, by displacing carbon monoxide from Hemoglobin competitively.

Hemoglobin has a much greater affinity for carbon monoxide than oxygen. This is because, a coordinate bond is formed with Carbon monoxide and Haem structure of the hemoglobin.

Carbon monoxide with Hemoglobin is called as Carboxy haemoglobin.

Presence of oxygen displaces the Carbon monoxide with Hemoglobin that is formed due to poisoning.

Hyperbaric chamber is a chamber which contains pure oxygen in a chamber. The atmospheric pressure is kept about three to four times than the normal, such that the replacement of Carbon monoxide from Haem can occur as fast as possible since this reduces the half life of the Carboxy haemoglobin.

It is advisable not to treat Carbon monoxide poisoning yourself.

Hyperbaric oxygen is used to treat the following conditions as well:

  • Infections
  • Wounds
  • Air bubble is blood
