Answer:

a) heat it from 23.0 to 78.3

q = (50.0 g) (55.3 °C) (2.46 J/g·°C) =  

b) boil it at 78.3

(39.3 kJ/mol) (50.0 g / 46.0684 g/mol) =  

c) sum up the answers from the two calculations above. Be sure to change the J from the first calc into kJ

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.

A chemist mixes 96.2 g of chloroform with 31.2 g of acetone and 98.1 g of acetyl bromide. Calculate the percent by mass of each
stiv31 [10]

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

The voltaic cell produces electric current from a spontaneous chemical reaction, but electrolytic reactions are not spontaneous.
scZoUnD [109]
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.
