Oxidanes is an effort, in a lecture/article format, to describe a specific chemical of the elements hydrogen and oxygen: water.

You are free to take this quiz based on the lecture/article oxidanes at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the {{chemistry resources}} and {{geology resources}} templates. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz[edit]

Point added for a correct answer:   
Points for a wrong answer:
Ignore the questions' coefficients:

1 Yes or No, The most common oxidane on the surface of the Earth is the liquid known as water.

Yes
No

2 Water occurs in the atmosphere as water vapor, and as a solid usually referred to as

.

3 Yes or No, Isotopic exchange between ice and water is found to take place in temperate glaciers.

Yes
No

4 True or False, The difference between geochemical reactions and astrochemical reactions is that astrochemical reactions are restricted to Earth.

False
True

5 Complete the text:

Oxygen-isotope analyses of ice and from the Saskatchewan Glacier, , and the Malaspina Glacier, Alaska, show that in ratios are likely to be of considerable value in glaciological research.

6 Yes or No, A clear liquid having the chemical formula H2O is called water.

Yes
No

7 True or False, Generally, geologic materials are isotopically lighter than natural water samples because of the preferential retention of 6Li in the solid phase.

TRUE
FALSE

8 Complete the text:

The discoveries of water ice on the , Mars and Europa add an component to the field, as in "astroglaciology".

9 Yes or No, Icequakes are seismic tremblings caused by sudden movement within a glacier or ice sheet, such as from a fracturing crevasse.

Yes
No

10 True or False, Anyone who has dropped an ice cube into a glass of water knows ice snaps under stress.

TRUE
FALSE

11 Yes or No, Known icequake triggers include opening and closing of the fractures called crevasses; glaciers tearing away from sticky bedrock; water runoff; and calving, the breaking off of an iceberg.

Yes
No
