The formula mass (Mr) of FeSO4 is the total mass of all the individual elemenets added together. So the Mr of FeSO4 = (1 x Fe) + (1 x S) + (4 x O) = 56 + 32 + 4x16 = 152 To calculate moles, the equation f...
2Li(s) + 3H2O(l) → 2LiOH(aq) + 2H2(g)
Different length hydrocarbon chains are separated by their different boiling points as longer chains will have stronger intermolecular attractions. The crude oil is heated and injected into the base of th...
The boiling point increases as the number of carbon atoms increases.
The enthalpy of atomisation is the enthalpy change when 1 mole of gaseous atoms is formed from its constituent element, in standard conditions.
