awhen chlorine is added to water, part of it evaporates into the air, causing the familiar odor, and the rest is present in water in the following forms:chlorine, hypochlorous acid, hydrochloric acid, hypochlorous anion, and chloride. 当氯增加到水时,一部分的它蒸发入空气,导致熟悉的气味,并且...

Think of chlorine and sodium chloride. One is incredibly toxic and dangerous, while the other is table salt. Scientific names are means of identifying the structure of a compound, not its uses, benefits or harms. I agree we should eat healthier and less processed foods. I just thinks its ...

17 The reaction of hydrogen with chlorine to form gaseous hydrogen chloride is exothermic.Which statement is correct? A A The total energy of bond formation is greater than the total energy of bond breaking. B The total energy of bond breaking is greater than the total energy of bond ...
The thing is, hydrogen is produced at the anode and chlorine at the cathode. So you need to see what the potential is for oxygen to form rather than hydrogen. The standard oxidation potential for water is -1.23 volts while that for Cl- is -1.36 volts. That is so close that in reality...
