Iron (II) sulfide reacts with hydrochloric acid according to the reaction: FeS(s) + 2 HCl(aq)→ FeCl2(s) + H2S(g) A reaction mixt
RideAnS [48]

The amount ( in moles  of excess  reactant that is left is 0.206 moles


Explanation

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

      = 0.652- 0.446  =0.206  moles

Alex's teacher showed him a model of gas particles in a sealed container. How should Alex change the model to show the particles
Inessa05 [86]

Answer:

  • Increased volume of particles in the container
  • greater vibration of particles

Explanation:

At higher temperature, the particles of the gas would be more active and vibrate more, or even have greater collisions. Alex can indicate this in the altered model to depict higher temperature.

Consequently, Charles law gives meaning to why there would be an increased volume of gas in the stable pressurized container, if the temperature were to be increased.

I hope this explanation was clear and concise?
