The type of chemical bond that forms when atoms lose or gain electrons to other atoms; these oppositely charged atoms are attracted to each other forming a bond.
What is an ionic bond?
100
An attraction between a slightly positive hydrogen atom and a slightly negative hydrogen atom, often oxygen or nitrogen.
What is a hydrogen bond?
100
A compound that releases a proton (a positive H+ ion) when it dissolves in water.
What is an acid?
100
The four main types of carbon-based molecules found in living things. . . .Double points (you must get all correct to earn these)
What are carbohydrates, proteins, lipids, and nucleic acids?
200
A substance made up of only one type of atoms.
What is an element?
200
A chemical bond that forms when atoms share a pair of electrons.
What is a covalent bond?
200
An attraction between molecules of the same substance.
What is cohesion?
200
Compounds that remove H+ ions from a solution (when these compounds dissolve in water, the solution has a low H+ concentration).
What is a base?
200
Molecules that contain carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur, that make up protein.
What are amino acids?
300
A substance made up of atoms of different elements bonded together in a certain ration.
What is a compound?
300
The attraction among molecules of different substances.
What is adhesion?
300
The measure of a solution's acidity, or H+ concentration, is made by using this tool.
What is the pH scale?
300
The state where both reactants and products are made at the same rate.
What is equilibrium?
400
An atom that has gained or lost one or more electrons.
What is an ion?
400
A type of molecule that shares electrons evenly in a covalent bond, and do not have electrically charged regions.
What is a nonpolar molecule?
400
When one substance dissolves in another.
What is a solution?
400
Each subunit in a complete molecule.
What is a monomer?
400
Catalysts for chemical reactions in living things.
What are enzymes?
500
Two or more atoms held together by covalent bonds.
What is a molecule?
500
The type of molecule that describes water, where the oxygen atom has a slightly negative charge, and the hydrogen atoms have slightly positive charges.
What is a polar molecule?
500
Two parts of a solution: 1) the substance that is present in the greater amount and that dissolves another substance, and 2) the substance that is being dissolved . . . double points - must get both right to get double
What is 1) solvent 2) solute
500
A large molecule, or macromolecule, made of many monomers bonded together.
