True.
Explanation:
Organic compounds can be found pure, but generally, they are in mixtures, such as the petroleum, so it is possible to the compound received be impure;
Organic compounds can be found in the three states: solid, liquid or gas. The state will depend on the molecular forces in it and its molar mass. For example, gasoline is liquid in the ambient temperature, natural gas is a gas, and the glucose is solid;
The main characteristic of the organic compounds is the presence of C and H, the other elements can or can't be in the structure: O, N, halogens, and S;
Because of the carbon can form chains, there are several million possible known organic compounds;
The spectroscopic would give some results such as composition, molar mass, and diffraction, and with these results, it would be possible to identify some chemical properties and the tests needs more identification.
The chemical formula of nickel (ii) hypochlorite is Ni(CIO)2. Nickel (II) has a charge of +2 while (CIO-) which is a poly atomic ion of chlorine and oxygen has a charge of -1. After balancing the charge of nickel with that of CIO- you get the chemical formula as Ni(CIO)2.
Answer:
Evaporation is a technique used to separate out homogeneous mixtures where there is one or more dissolved salts.

Answer:
The atomic radius of atoms generally decreases from left to right across a period. There are some small exceptions, such as the oxygen radius being slightly greater than the nitrogen radius. Within a period, protons are added to the nucleus as electrons are being added to the same principal energy level.
