Two unlabelled bottles containing clear, colourless liquids are found in the organic section of the chemical storage room. describe the chemical test that could be conducted in order to determine whether the two substances are unsaturated or saturated.

The very first step you should do is to bromine water to each of them. Then you can recognize the unsaturated compound, because as you know it will  decolourize during adding bromine water, so we can make a conclusion that it will undergo as an addition reaction. Hope you will agree with me and fing this answer helpful for you. Regards!

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Order of filling levels and sublevels of electrons: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²3f¹⁴5d¹⁰6p⁶for an element with 5 electrons in the 3d energy level: full configuration: 1s²2s²2p⁶3s²3p³.
