WebJun 20, 2024 · These are four questions and four answers. In oxidation-reduction reactions at least one element increase its oxidation state and other (or even the same) reduce its oxidation state. So, you have to determine, for each reaction if there is a change in the oxidation states of some elements.

Iron (II) sulfide reacts with hydrochloric acid according to the reaction: FeS (s)+2HCl (aq)→FeCl2 (s)+H2S (g) A reaction mixture initially contains 0.250 mol FeS and 0.652 mol HCl. Once the reaction has occurred as completely as possible, what amount (in moles) of the excess reactant is left? WebOct 27, 2024 · FeS(s) + 2HCl (aq) → FeCl2 (s) + H2S (g) by use of mole ratio of FeS: HCl which is 1:2 this means that 0.223 mole of FeS reacted completely with 0.223 x 2/1 =0.446 moles 0f FeCl2. HCl was in excess because 0.446 moles of HCl reacted and initially there was 0.652 moles. Therefore the amount that was left
