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?

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?
