The mineral dolomite contains magnesium carbonate. This reacts with hydrochloric acid. MgCO3(s) + 2 HCl(aq) + CO2(g) + MgCl, (aq) + H20(0) a. Write the net ionic equation for this reaction and identify the spectator ions. (If needed, use H3O+ for the hydronium ion. Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (ag) or (3). If a...

Can anyone tell me how to can the -3 and
+5 on the of N? I know -3 to +5 is oxidized. But I don't know where
is -3 and +5 come from.
Same question how do you get 0 and +4?
-3 +1 +1 +5 -2 NH3(aq) + 20%(9) ► HNO3(aq) + H20(1) The oxidation state of the nitrogen atom is – 3 before the reaction and +5 after the reaction. That means the nitrogen atom is oxidized. +4...
