The energy required to remove an electron from 1 mole of gaseous atoms to form 1 mole of gaseous 1+ ions

Benzene's delocalised π system of electrons makes it not quite electron rich enough for the reaction to take place. The lone pair from the -OH group in phenol adds enough electron density into the ring so...

Balanced equation: H₂SO₄ + 2NaOH → 2H₂O + Na₂SO₄moles of NaOH = c x v = 0.1 mol dm^-3 x (20/1000) dm³ = 0.002 molStoichiometry: ...

NaCl cannot conduct electricity in the solid state as the ions are held in an ionic lattice and therefore are not free to conduct. NaCl can conduct in the melt as the ions become mobile and therefore are ...

The nucleus contains positively charged protons which attract the negative electrons, the first ionisation energy is the energy required to overcome this attraction and remove 1 electron As you go down a ...
