L’alumnat de 2n d\u2019ESO hem estudiat les reaccions qu\u00edmiques. Aquestes s\u00f3n molt variades, diverses i, fins i tot, impressionants.<\/p>\n
Una reacci\u00f3 molt espectacular \u00e9s la reacci\u00f3 de la catalasa. La catalasa \u00e9s un enzim que tenim els \u00e9ssers vius i descompon l\u2019aigua oxigenada en aigua i oxigen.<\/p>\n
Al v\u00eddeo podem observar com afegint llevat viu a una concentraci\u00f3 d\u2019aigua oxigenada elevada (H2O2) s\u2019allibera oxigen tant r\u00e0pidament que fa molta escuma i allibera calor.<\/p>\n
Com podeu veure, experimentant amb la ci\u00e8ncia som capa\u00e7os d’arribar a conclusions i aprendre nous continguts.<\/p>\n","protected":false},"excerpt":{"rendered":"
