When a liquid sample is taken from sea level to a higher elevation, what happens

Question

When a liquid sample is taken from sea level to a higher elevation, what happens to the external (atmospheric) pressure on the liquid and the boiling point of the liquid? pressure goes up, but boiling point goes down pressure goes down, but boiling point goes up both decrease both increase When the equilibrium expression is written for the reaction N_2(g) + 3F_2(g) rightleftharpoons 2NF_3(g) What is the exponent of the concentration of fluorine, F_2? 0 1 2 3 A sample of gas collected at 21.0 degree C and a pressure of 660 torr has a volume of 1.83 liters. What volume in liters will the gas occupy at 38.0 degree C under a pressure of 500 torr? 1.33 2.56 4.37 2.28 Iodine, I_2, is very slightly soluble in water, a polar solvent, but quite soluble in toluene, a nonpolar solvent. What can be inferred about the nature of the I_2 molecule? It is nonpolar. It is ionic. It is polar. Nothing can be inferred. The boiling point of a solution of sugar water is higher than that of pure solvent. Lower than that of pure solvent. the same as that of pure solvent. impossible to determine. Which of the following pressure units is largest? One psi one torr one mm Hg one atm An ion in solution that is surrounded by water is a(n) _____________ ion. Saturated hydrated colloid osmotic Which of the following correctly arranges the physical states of matter (gas - g, solid - s, liquid - l) in order of increasing energy of the particles (lowest to highest)? S

Explanation / Answer

8.

Pressure decreases at elevations due to which the boiling point also decreases so

c.) both decrease

9.

d.)3 since its balanced form has coefficient 3

10.

p1v1/t1 = p2v2/t2

v2 = 660*1.83*311 / 500 *294 = 2.56 L

so b)2.56

11.

a. it is non-polar because it was polar it would have dissolved in water and it is non-polar because it dissolves in a non-polar solvent like tuolene.

12.

a.Higher than that of pure solvent because there is an elevation of boiling point on addition of sugar since it is a colligative property

13.

d.one atm = 14.6959 psi = 760 torr = 760 mm Hg

14.

b.hydrated

15.

a. s<l<g(least energy in solids where particles cannot move at ordinary temperatures and most energy in gases where they wonder about at room temperature)

16

since it is exothermic there should be low temp and high temp should be avoided

c.high temperature

17.

p1v1 = p2v2

v2 = 5*1/3 = 1.67

18.

a.steam condenses to liquid because steam gives up heat to water and condenses
