Question 1

What are the 6 properties of water?

Answer 1

1. High specific heat
2. Capilary Action
3. High vaporization temperature
4. Surface Tension
5. Ice Floats
6. Universal Solvent

Question 2

Trace elements:

Answer 2

elements required in very small quantities (like iron, copper, flourine, iodine, zinc, and maganese), they already exist in the body but make up less than 0.01%

Question 3

A compound is:

Answer 3

a substance consisting of two or more different elements combined in a fixed ratio

Question 4

Radioactive isotopes:

Answer 4

can help or harm us, like radioactive iodine can kill cancer but also chernobly yk

Question 5

The distribution of electrons…

Answer 5

determines an atom’s chemical properties (because it puts their position on the periodic table, like O has one more electron than N and so it isone more to the right)

Question 6

Ionic bonds are attractions between…?

Answer 6

ions of opposite charges

Question 7

Water’s hydrogen bonds moderate temperature:

Answer 7

strong hydrogen bonds between water molecules, which require a significant amount of energy to break, meaning it takes a large amount of heat to raise the temperature of water by even a small degree.
therefore water also has high vaporization temperature, as hydrogen bonds must be broken to let molecules become gas.
