Se añade agua a 40 kg de óxido de calcio (cal viva) hasta obtener 52,8 kg de hidróxido de calcio (cal apagada). La ecuación ajustada de la reacción es:

CaO (s) + H2O (I) → Ca(OH)2 (aq)

¿Qué cantidad de agua ha sido necesaria para llevar a cabo esta reacción?

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
