2. A student reacted 2.025g of aluminium metal with an excess of hydrochloric acid, HCI.
The equation for this reaction is shown below:
2AI (s) + 6HCl(aq) → 2AlCl3 (aq) + 3H₂(g)
a) (i) Calculate how many moles of Al reacted
2.025 -
(ii) Calculate the number of atoms of Al in
2.025g?
(iii) Deduce the number of moles of H₂ formed?
(iv) The ions in AlCl3 are Al³+ and Cl. How many moles of ions are there in 1 mole of AICI3?
b) (i) Draw the dot and cross diagram for AICI 3.
