WebZenu Destroyer of Worlds (AK) bleach is basically a solution of sodium HypoChlorite, or NaClO. This is a salt that contains the anion of the weak acid HClO, hypochlorous acid, and the cation of the strong base, NaOH. Because NaOH is a strong base, it fully dissociates into Na+ ions and OH- ions. WebJan 30, 2024 · This phenomenon can be used to analyze boiling point of different molecules, defined as the temperature at which a phase change from liquid to gas occurs. Ethanol, CH 3 CH 2 − O − H, and methoxymethane, CH 3 − O − CH 3, both have the same molecular formula, C 2 H 6 O. They have the same number of electrons, and a similar length.
