The balanced chemical equation is Pb(NO3)2+ 2KI produces PbI2 + 2K(NO)3
.4 L of KI × (.375 mol/L of KI) × (1 mol of PbI2 / 2 mol of KI) × (461 g of PbI2/1 mol of PbI2)
=34. 6 g of PbI2 precipitate.
<span>Enthalpy is regarding the amount of heat that is given off or taken in during the process of a reaction, while entropy is about the disorderliness of a reaction.
Both are related in the equation ∆G=∆H-T∆S, where ∆G is the Gibbs free energy. So we can say that a reaction is both enthalpy and entropy driven. It's like, both of them are interlinked with each other. </span>
Many acids will react with a metal to produce hydrogen gas and a metal salt.
Hope this helped :)
<span>Answer:
Moles C10H16O = 24.6 g/ 153.23 g/mol = 0.161
Moles benzene = 98.5 g / 78.1121 g/mol = 1.26
Mole fraction benzene = 1.26 / 1.26 + 0.161 = 0.887
vapor pressure = 100 x 0.887 = 88.7 mm Hg</span>
