what are atoms?
100
The attraction between a hydrogen atom on one water molecule and an oxygen atom on a different water molecule is known as hydrogen bonding.
What is a hydrogen bond?
100
Giant-molecules, made of thousands of smaller molecules. Formed by a process called polymerization, which is when monomers merge to form polymers.
There are 4 types of these.
What are macromolecules?
100
A process when reactants change into a product
What is a chemical reaction?
100
List the 4 types of macromolecules.
Carbohydrates, lipids, nucleic acids, and protein.
200
The combination of positively charged atoms, and no charge atoms.Otherwise known as the center of an atom
What is the nucleus?
200
A substance that is dissolved, and a substance that dissolves the other substance. Often compared to salt and water.
What is a solute and solvent?
200
A macromolecule that serves as energy for the body. Can be simple or complex. Contains carbon, hydrogen, and oxygen (CHO)
ex. bread, pasta, vegetables
What is a carbohydrate?
200
The result of a chemical reaction. Starts with the letter p
What is a product?
200
A substance created by chemically combining two or more elements in a very specific way
What is a compound?
300
Version of element with the same amount of protons, but a different amount of neutrons
What is an isotope?
300
Attraction between molecules of the same substance.
What is cohesion?
300
A type of macromolecule that is made up of fatty acids and glycerol combined. They contain carbon, hydrogen, and oxygen (CHO). Usually used as a insulator
ex. fats, oils, waxes
What is a lipid?
300
Substance that is used in a chemical reaction to make new substances. Starts with the letter r.
What is a reactant?
300
The attraction of molecules of DIFFERENT substances
what is adhesion
400
The bond in which one or more electrons move from one atom to another
What is an ionic bond??
400
A scale which represents/measures how acidic (the number of H+ ions), or basic (the number of OH- ions) a solution is.
What is pH scale?
400
A type of macromolecule that contains carbon, hydrogen, oxygen, and nitrogen (CHON). They are made of amino acids.
ex. meat, eggs, dairy
What is a protein?
400
Cells produce this. A substance that quickens the pace of a chemical reaction by lowering reaction activation energy
What is a catalyst?
400
building blocks of protein
What are amino acids?
500
The subtle attraction of molecules close together; an intermolecular force of attraction. Can allow animals to stick on surface, defying gravity. Often seen at work on a geckos feet.
What is the Van der Waals Forces?
500
Fragile acids that keep pH level steady. They can interact with sharp acids/bases and prevent changes in pH.
What is a buffer?
500
A type of macromolecule that contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHONP). Made of nucleotides, and transfers genetic information in cells.
ex. DNA, RNA
What is a nucleic acid?:max_bytes(150000):strip_icc()/RNA_vs_DNA-5b633a1fc9e77c002ca252a1.jpg)
500
A protein that speeds up chemical reactions. Acts as biological catalyst. Is often compared to a puzzle piece, as it connects to a substrate
What is an enzyme?
500
Composed of 2 or more elements, or compounds mixed together physically. Like salt and pepper, or sugar and sand
starts with the letter m
What is a mixture?
