Answer:
</h2>
Nitrogen forms many thousands of organic compounds. Most of the known varieties may be regarded as derived from ammonia, hydrogen cyanide, cyanogen, and nitrous or nitric acid. The amines, amino acids, and amides, for example, are derived from or closely related to ammonia.

Explanation:
</h3>
A carbohydrate has only Carbon, Hydrogen and Oxygen, with the hydrogen and oxygen in the ratio 2:1.
Examples are glucose C6H12O6 and table sugar C12H22O11
A protein is made of amino acids. Amino acids have an amino group which is −NH2.
So without nitrogen atoms the compound cannot be a protein.
Nucleic acids are organic compounds that contain carbon, hydrogen, nitrogen but they also contains phosphorus and oxygen. They are made of smaller units called nucleotides.
So;
Simple Amines are the class of organic compounds that only contains Carbon, Hydrogen and Nitrogen.
Answer:As you increase your altitude, the air pressure decreases because there is less air above pressing down. Therefore that air temperature also decreases proportionately.

Answer:
2CaO + 2CO2 → 2CaCO2 + O2 is right
Amount of silver nitrate taken = 269.μmol
Volume of the solution = 300. mL
Concentration of a solution is generally expressed in terms of molarity. Molarity is defined as the moles of a substance present per liter of the solution.
We want the concentration in millimoles/L.
Converting μmol to millimol solute:
μ = 0.269 millimol
Volume from mL to L:
Therefore concentration of the chemist's solution =
