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

Answer:
A. Charles's law
Explanation:
Charles's law states that volume of given gas is directly proportional to the temperature at constant pressure. Directly means if one increases, the other also increases. If temperature of a gas increases, the particles of gas molecules start expanding. Due to expansion, the particles occupy more space and thus volume of the gas molecules increased.
