how do u do determineee it?can u please give me those for these elements:rubidiumcalciumaluminumoxygenironmercuryand leadpleaseeeee help!and please if u can,gimme a good website i can practice on
The ethyl alcohol acted as a solvent for the inkInk is made up from different color dyesThe heavier the molecule of the dye, the slower it will move though the paper.
You determine these elements by looking at the periodic table of elements1Rubidium - Rb - 37 37 protons and electrons Atomic Mass - Atomic Number Neutrons - 85g - 37 48 Charge: + 1 2Calcium - Ca - 20 20 protons and electrons 20 neutrons Mass: 20 g Charge: + 2 3Aluminum - Al - 13 13 protons and electrons 14 neutrons Mass: 27 g Charge: + 3 4Oxygen - O - 8 8 protons and electrons 8 neutrons Mass: 16 g Charge: - 2 5Iron - Fe - 26 26 protons and electrons 30 neutrons Mass: 56 g Charge: + 2, + 3 6Mercury - Hg - 80 80 protons and electrons 121 neutrons Mass: 201 g Charge: + 1, + 2 7Lead - Pb - 82 82 protons and electrons 125 neutrons Mass: 207 g Charge: + 2, + 4
Cellophane and illusional self are both half rightAs the alcohol travels through the paper by capillary action it drags the various chemicals that make up the brown ink with itSome of the chemicals travel faster than othersThis causes them to separate and create different color bands.
Those results are the well known effect of treating chromatography paper with ethyl alcoholI did the same thing last night at a party, to the amazement of all present (and sober)A more general answer to your?: Because they can't UNhappen!
