Step 1: Work out the moles of NaOH and HCl added into the solution 10cm^3 of 1M NaOH would mean that there is 10cm^3/1000cm^3 x 1M present, i.e. 0.01 moles 15cm^3 of 0.5M HCl would mean that there ...
The atomic radius of an atom is the distance from the atom's nucleus to its outermost electron. Moving across Period 3, the number of protons in the nucleus increases - for example sodium has 11 protons, ...
London dispersion forces. These arise because: 1. Electrons within the halogen molecule are constantly moving and at any one instant there is an uneven distribution of electrons within the molecule. 2. Th...
Mr of MgCl2 = 24.3 + 2(35.5) = 95.3 Moles added = 2.11/95.3 = 0.02214 Mol of cl- added = 20.02214 = 0.04428 Conc = 0.04428/(3010-3) = 1.48 moldm-...
