100
This subatomic particle has a negative charge and orbits an atoms nucleus.
What is an electron
100
In water, there are 2 Hydrogen atoms and this many oxygen atoms present.
What is 1
100
A substance that has a pH of 13 is called this.
What is a base
100
Carbon has 4 of these allowing it to bond to 4 different elements
What are valence electrons
100
This is the end product of a reaction.
What is a product
200
These two subatomic particles are responsible for the atomic mass and are located in the nucleus of an atom.
What are protons and neutrons
200
This is the characteristic that gives water a slightly positive charge at one end of the molecule and a negative charge at the other end.
What is polarity
200
This scale is used to determine whether something is an acid, neutral, or a base.
What is the pH scale
200
The ability of Carbon to bond to itself allows it to make long chains of these types of molecules, which make up all of life.
What are macromolecules
200
These things enter a reaction
What are reactants
300
Dating fossils, tracing substances within a body, treating cancer, and killing bacteria are a few uses for these.
What are isotopes
300
Because of the polarity and weak hydrogen bonds of water, water is the best__________, allowing it to dissolve other substances.
What is solvent
300
H2O plus CO2 results in this type of rain.
What is acidic rain
300
Within the carbohydrate group, another name for glucose, a "simple" sugar, is called this.
What is a monosaccharide
300
This is a biological catalyst responsible for speeding up reactions. It reacts with a substrate and ends in "ase"
What is an enzyme
400
Atoms that either loose or gain electrons are involved in this type of bond, resulting in either a positive or negative charge.
What is an ionic bond
400
These two properties of water allow capillary action in plants to occur.
What is adhesion and cohesion
400
These are weak acids and bases that react with strong acids and bases preventing sharp increases in pH level
What is a buffer
400
Long chains of these monomers make up proteins.
What are amino acids
400
This is the "key" in the enzyme-substrate complex that reacts with the enzyme. It ends in "ose"
What is the substrate
500
An atom that has 6 electrons, 6 protons, and 6 neutrons is said to be this.
What is neutral
500
This is a slight attraction between opposite charged regions of molecules that allows geckos to stick to the walls of an aquarium.
What is van der Waals forces
500
A substance which has a high concentration of Hydrogen ions is called this.
What is an acid
500
This type of nucleic acid is made with the 5 Carbon sugar called ribose and is involved with the genetic make up of something.
What is RNA
500
Whenever chemical bonds are formed this is absorbed. Whenever chemical bonds are broken the is released.
