Calculate Mr(NaOH): Mr(NaOH) = 23 + 16 + 1 = 40, Calculate NaOH moles: n= m/Mr, n= 8.0/40, n= 0.2 moles, Calculate NaOH concentration:(converting from cm³ to dm³ by /1000) c= n/v, c=...

First, we have atomic and ionic radii which, as the name suggests, refer to the size of the atom, or the ion in the latter case. Radii increase as you go down a group (i.e. Halogens), since the number of ...

Sodium Chloride has a high melting point, as it has a giant ionic lattice hence has strong electrostatic forces of attraction between oppositely charged ions, which requires lots of energy to overcome the...

Balancing equations will become natural if you do it long enough but takes a bit of practice and can be tedious! It can be a bit of trial and error at times. It is important to remember that numbers of el...

Well this depends whether you require the moles of gas, solid or solution as to which equation you use, moles relate the mass of the atom of interest to that of the number of atoms in 12 grams of carbon-1...
