Web1 day ago · The PEG-CA inhibited the oxidation of –CH 3, –CH 2-, as well as the intermediate products and –OH in coal underwent etherification reaction to form numerous ether bonds. The citric acid degraded the transition metal ions in coal, increased the energy of reaction, and inhibited coal spontaneous combustion. WebSep 16, 2024 · When HCl is dissolved in H 2 O, it completely dissociates into H + (aq) and Cl − (aq) ions; all the HCl molecules become ions: H C l → 100 % H + ( a q) + C l − ( a q) Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid. HC 2 H 3 O 2 is an example of a weak acid:
