PbCl₂(s) ⇄ Pb²⁺(aq) + 2Cl⁻(aq)
Pb(CH₃COO)₂(s) → Pb²⁺(aq) + 2CH₃COO⁻(aq)
At lead acetate disolution, concentration of lead cations will increase. According to Le Chatelie's principle equilibrium will be displaced towards formation of solid lead chloride.
Answer:
42.6 % CHCl₃, 13.83 % C₃H₆O and 43.5 % CH₃COBr
Explanation:
This is a solution with 3 compounds:
96.2 g of CHCl₃
31.2 g of C₃H₆O
98.1 g of CH₃COBr
Total mass of solution is : 96.2g + 31.2 g + 98.1g = 225.5 g
Percent by mass is, the mass of the compounds in 100 g of solution
Let's prepare the rule of three
225.5 g of solution have ____ 96.2 g ___ 31.2 g _____98.1 g
100 g of solution would have ____
(100 . 96.2) / 225.5 = 42.6
(100 . 31.2) / 225.5 = 13.83
(100 . 98.1) / 225.5 = 43.5
I believe the correct answer is true. Voltaic cells produces current from spontaneous reactions and is also known as galvanic cell. For electrolytic cells the reactions are not spontaneous and requires input of current for the reaction to occur.
