En 1774, el químico británico Joseph Priestley preparó el oxígeno por calentamiento del óxido de mercurio (II), de acuerdo con la siguiente ecuación: HgO = Hg + O2
Si se obtienen 64.7mL de oxígeno, ¿Qué cantidad de Óxido de mercúrico se debió haber utilizado, si se sabe que tiene una pureza del 86% en masa?

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

What is the average rate of the reaction between 10 and 20 s?
