Question

chemistry

A room-temperature solution is saturated in both KCI and CO_2. When the solution is heated to near boiling, which of the following is most likely to occur? Some KCI precipitates out of solution. Some CO_2 bubbles out of solution. Nothing is likely to happen. Some CO_2 bubbles out of solution and some KCI precipitates What is the molality a 4.0 M NaOH solution? The density of the solution is 1.04 R/mL. (Molecular weight of NaOH is 40 g/mol) 0.15 m 0.18 m 4.5 m 4.0 m 3.8 m A pressure of 3.5 atm in CO_2 is required to maintain a 0.12 M CO_2 concentrate in soda. Calculate the Henry's Law constant for CO_2. 29.2 0.42 2.9 Times 10^1 3.4 Times 10^-2 4.2 Lauryl alcohol, a component of coconut oil, is used to make detergents. A solu of 5.00 g of lauryl alcohol in 0.100 kg of benzene freezes at 4.1 degreeC. What is the me mass of lauryl alcohol?

Answer 1

Answer:

1). d).Some CO2 bubbles out of solution and KCl precipitates.

2). e) 3.8 m

Molality = Molarity/density

Molality = 4/1.04

= 3.84 m

3). d).3.4*10-2

Henry's law constant (K) = C/P

= 0.12/3.5

= 0.034
