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

Why is it important to test the crucible for cracks before heating it?
solmaris [256]

It important to test the crucible for cracks before heating it because it can break while performing the chemical reaction.

The crucible and the lid should be inspected to check for the before heating it to prevent the breaking while performing the reactions. if there are some breaks in the crucible then if we heat the crucible it can lead to breaking of the whole crucible and the material  from the crucible to come out and it will come in contact with the lid.

The crucible plays a important role while preforming the reactions, so. it important to check the cracks of the crucible before the heating of the crucible.

Consider the densities of the
serious [3.7K]

The Percent error in the calculation of densities of the metal during experiment is 0.03 %

<h3>What is Percentage error?</h3>

Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.

Percent error = [Experimental value - Theoretical value] / Theoretical value x 100%

Percent error = 7.83 -7.86 / 7.86 x 100

= 0.03 %
