Summary
| Description |
English: Potassium chlorate and gummy bear
- A gummy bear is dropped into a test tube containing molten potassium chlorate. The gummy bear is rapidly consumed giving off a lot of smoke. The potassium chlorate first melts (an endothermic process), and then the molten potassium chlorate decomposes liberating oxygen (an endothermic reaction). The sugar present in the gummy bear undergoes rapid oxidation (exothermic reaction). KClO3(s) → KClO3(l) 4KClO3 → KCl + 3KClO4 KClO4 → KCl + 2O2 C12H22O11(s) + 12O2(g) → 12CO2(g) + 11H2O(g) Planned and performed by Marina Stojanovska, Miha Bukleski and Vladimir Petruševski, Department of Chemistry, FNSM, Ss.

- „Гумена“ бонбона се става во епрувета која содржи стопен калиум хлорат. Бонбоната брзо реагира создавајќи многу чад. Најпрвин калиум хлоратот се топи (ендотермен процес), а потоа стопениот калиум хлорат се разложува ослободувајќи кислород (ендотермна реакција). Шеќерот присутен во бонбоната стапува во реакција на брза оксидација (егзотермна реакција). KClO3(s) → KClO3(l) 4KClO3 → KCl + 3KClO4 KClO4 → KCl + 2O2 C12H22O11(s) + 12O2(g) → 12CO2(g) + 11H2O(g) Осмислено и изведено од Марина Стојановска, Миха Буклески и Владимир Петрушевски, Институт за хемија, ПМФ, УКИМ, Скопје. |
