Methane (/ËmÉÎ¸eÉªn/ or /ËmiËÎ¸eÉªn/) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen).ethane can be produced by hydrogenating carbon dioxide through the Sabatier process. Methane is also a side product of the hydrogenation of carbon monoxide in the Fischer-Tropsch process. This technology is practiced on a large scale to produce longer chain molecules than methane.
AlCl3 dissolves in water to give Al3+(aq) and Cl-(aq), which is ionic behaviour Hydrated AlCl3, Al(H2O)6Cl3, is undoubtedly an ionic solid, containing the Al(H2O)6 3+ cation AlCl3 sublimes at low temperature, giving vapour of composition Al2Cl6, with tetrahedral Al and two bridging Cl.rom the rules, phi=charge on cation/charge on anion where phi is the ionic potential of the cation. Now Al3+ has high +ve charge on it, so it can distort the cl-cation easily, thus inducing covalent character into it. See Wikipedia for more details.
