Answer:
0.219 mol HCI
Explanation:
Iron(II) sulfide reacts with hydrochloric acid according to the reaction:
FeS (s) + 2HCl (aq) → FeCl2 (s) + H2S (g)
A reaction mixture initially contains 0.223 mol FeS and 0.665 mol HCl.
Once the reaction has occurred as completely as possible, what amount (in moles) of the excess reactant remains?
the input force would be 75 N
if the output force is 150 N you divide that in half which leaves with 75 N !! :)
yes
