Water is a molecule made up of what types of atoms linked together?
What is Hydrogen and Oxygen?
This is an atom or group of atoms that have a positive or negative charge.
What is an Ion? p121
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
Water is sometimes called this because it can dissolve nearly everything.
What is Universal Solvent?
This forms between atoms of nonmetals when they share valence electrons.
What are covalent bonds? p125
What are reactancts?
This is how many atoms are in a molecule of ammonia which has a chemical formula of NH3
What is 4 atoms?
This is a weaker force of attraction between moleules that is strong enough to make molecules "stick" together.
What is a hydrogen bond?
This is an easier way to show covalent bonds for a molecule or compound.
What is a structural formula model? p126
This is the chemical formula for calcium carbonate which has one calcium atom, one carbon atom, and three oxygen atoms.
What is CaCO3
This determines how bonds form or break.
What is valence electrons? p116. p1
This Phenomenon allows some things to float on the surface without breaking.
What is surface tension?
The phenomena that occurs when individual molecules are so strongly attracted to each other that they tend to stay together.
What is cohesion?
This is held together by a force of attraction that keeps the positive and negative ions together.
What is an ionic compound? p123
Carbon tetrachloride will not dissolve in water so it must be made up of these types of molecules.
What are nonpolar molecules?
This means having the same type of nucleus and two atoms of the same element.
What is a homonuclear diatomic? p118
The type of liquid that will dissolve a nonpolar substance.
What is a nonpolar substance?
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
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?
This is the only element with the necessary properties for life.
What is Carbon? p.127
