Water is a molecule made up of what types of atoms linked together?

What is Hydrogen and Oxygen?

100
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
What is a polar molecule?
100

This is an atom or group of atoms that have a positive or negative charge.

What is an Ion? p121

100
Water that has certain dissolved ions in it.
What is hard water?
100

This is a way to write a compound showing the elements in the compound and the ratios of the atoms of each element.

What is a chemical formula? p116

200

Water is sometimes called this because it can dissolve nearly everything.

What is Universal Solvent?

200
The substance type that does not dissolve in water.
What is nonpolar?
200

This forms between atoms of nonmetals when they share valence electrons.

What are covalent bonds? p125

200
These are substances that undergo a chemical change.

What are reactancts?

200

This is how many atoms are in a molecule of ammonia which has a chemical formula of NH3

What is 4 atoms? 

300

This is a weaker force of attraction between moleules that is strong enough to make molecules "stick" together.

What is a hydrogen bond?

300
A molecule that has no overall charge because there is not an imbalance in the way electrons are shared.
What is a nonpolar molecule?
300

This is an easier way to show covalent bonds for a molecule or compound.

What is a structural formula model? p126

300

This is the chemical formula for calcium carbonate which has one calcium atom, one carbon atom, and three oxygen atoms.

What is CaCO3

300

This determines how bonds form or break.

What is valence electrons? p116. p1

400

This Phenomenon allows some things to float on the surface without breaking.

What is surface tension?

400

The phenomena that occurs when individual molecules are so strongly attracted to each other that they tend to stay together.

What is cohesion?

400

This is held together by a force of attraction that keeps the positive and negative ions together.

What is an ionic compound? p123

400

Carbon tetrachloride will not dissolve in water so it must be made up of these types of molecules.

What are nonpolar molecules?

400

This means having the same type of nucleus and two atoms of the same element.

What is a homonuclear diatomic? p118

500

The type of liquid that will dissolve a nonpolar substance.

What is a nonpolar substance?

500
The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.
What is surface tension?
500

The reason water is a liquid at room temperature when all other chemically similar substances are gasses at room temperature. This also makes the surface tension of water larger than that of many other substances.

What is hydrogen bonding? p133

500

If you were able to count the molecules in a substance, which would have more molecules, 1 liter of liquid water, or 1 liter of ice?

What is liquid water?

500

This is the only element with the necessary properties for life.

What is Carbon? p.127
