03. El óxido de magnesio (Mgo) es uno de los principales componentes en la fabricación de refractarios básicos, se obtiene a través del calentamiento del carbonato de magnesio
(MgCO3):
MgCO3() → MgO(s) + CO2(g)
Si se desea obtener 304 g de óxido de magnesio, ¿qué cantidad de carbonato de
magnesio con una pureza de 76% se deberá emplear?

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
