Liquid oxygen collected into a test tube is found to be
a. nonmagnetic.
b. ferromagnetic.
c. paramagnetic.
d. diamagnetic.
Homework Answers
(C) paramagnetic
Paramagnetism of Liquid Oxygen
As a result of the parallel spin of unpaired electrons, molecular
oxygen is paramagnetic and is attracted by a magnetic field. This
is demonstrated by bringing a large test tube with a small amount
of liquid oxygen close to a powerful magnet. The test tube is
visibly attracted to the magnet.

14. Lab Exercise 5-1 is an interesting way to run these test tube experiments without oxygen - seal the tube with a layer of clear mineral oil on top (see the figure in the manual). Based on this figure and the Table of Results for this experiment, if the sealed tube is all green or slightly blue but the unsealed tube has any amount of yellow, what type of energy metabolism does that organism have? a. Oxidative only b. Oxidative...

PART A: If a test tube is placed over a flame, the gas that is collected creates a combustion reaction. What is the balanced equation for the reaction? PART B: The vinegar and baking soda react to generate carbon dioxide gas. The gas is then bubbled into the limewater. The first gas to come out of the tube will be mostly air until the large test tube fills up with the carbon dioxide gas. a. Write a balanced equation for...

A piece of metal is dropped into a test tube of light-blue liquid. The piece of metal immediately starts fizzing and dissolving, and you can sense the heat radiating from the test tube even when your finger is an inch away. 2) A spoonful of salt is added to a beaker of water, and stirred. The salt dissolves completely in the water. 3) Two clear liquids in separate test tubes are mixed in a beaker. Within a minute, you observe...
