The empirical formula of hydrogen peroxide is………. 02:07 The law which does not follow from Dalton’s atomic theory is……… 10:07 The mass of a molecule of carbon-14 dioxide (""^(14)CO(2)) is g. 01:55 An atom of sulphur is times heavier than an atom of carbon. 02:07 The...
the formula mass may be correctly referred to as a molecular mass. Consider chloroform (CHCl3), a covalent compound once used as a surgical anesthetic and now primarily used in the production of the “anti-stick” polymer, Teflon. The molecular ...
for 5 minutes. Transfer the crucible to the balance and find the mass of the crucible and magnesium oxide. PreLab Questions: 1. Why is it necessary to heat the crucible before weighing it the first time? 2. With what element or elements does the magnesium combine when it is heated in th...
