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...

Formula of Iron 3 Nitrate is Fe(NO3)3. Moles = mass/Mr.

Already given mass = 2.16g

Want to work out amount in moles.

Need to calculate Mr of Iron 3 nitrate, put into equation with mas...

A redox reaction is a reaction where both reduction and oxidation are happening simultaneously.

Reduction is the gain of electrons, where as oxidation is the grian of elctrons. I like to remember t...

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...
