Question

I need to name an ionic compound containing a transition metal cation and a halogen anion. Below are the rules I should follow to write the correct name for such compound, but one of the options is incorrect: identify and select it. Select one: a. Identify the metal and write its name first b. Use the periodic table to work out the charge (oxidation number) on the transition metal according to the group in the periodic table c. From the charge of the anion work out the charge of cation as Roman number in parenthesis: specify this charge in the name as a Roman number in parenthesis. d. Write the number of the anion after the name of the metal Consider this reaction: 2 Al(s) + 6 H" (aq) + 2 Al** (aq) + 3 H, (9) Which process does H' (aq) undergo and why? Select one or more: Ca. H(aq) is reduced, because it gains electrons b.H (aq) is oxidised, because it gains electrons c. H(aq) is reduced, because it looses electrons lan) is oxidised, because it looses electrons
