The part which would indicate that this compound is amine is located in the upper part attached to the second carbon atom or the middle carbon atom. It is an NH2 attached to the carbon atom. Amine is a derivative of ammonia, where one hydrogen atom of the ammonia is being replace by an alkyl or aryl group.
When should lab participants look at the safety data sheet (sds) of a substance--- before using the substance
Which of the following will be found on a safety data sheet?
The SDS includes information such as the properties of each chemical; the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting the chemical.
Where can safety data sheets be found?
To obtain SDS, get them from the manufacturer. They may be sent with the chemical order (paper copy or e-mail attachment). Otherwise, go to the manufacturer's website and download it or request a copy
What is the purpose of a safety data sheet?
A Safety Data Sheet (formerly called Material Safety Data Sheet) is a detailed informational document prepared by the manufacturer or importer of a hazardous chemical. It describes the physical and chemical properties of the product

Answer:
a, b, c Flask B
Explanation:
The root mean square velocity of a gas is given by
V = √ ( 3RT/M)
where m is the molar mass, T is the temperature of the gas and R is the gas constant.
Therefore we have that the the velocity of the gas molecules is inversely proportional to the square root of the molar mass . That is the heavier the molecules the slower they will move which makes sense and the lower its kinetic energy.
The greater the velocity the more collisions the gas will have against the walls of the container.
The molar mass of CO and N2 are 28 g/mol while H2 is 2 g/mol. Hence hydrogen the lightest will have a greater kinetic enrgy, the greatest root mean square velocity and the greatest number of collisions with the wall of the container.
Notice that the pressure given for each is of the gases is different being the greatest for CO but pressure does not have an effect on the kinetic enery of the molecules.
