100

This is the negatively charged particle that "orbits" the nucleus of an atom

What is an electron?

100

The minimum amount of energy needed for a chemical reaction to begin

What is activation energy?

100

This is a postively charged ion

What is a cation? (Remember: PAWSitive🐱)

100

This is the universal solvent

What is water?

100

These are the number of tiers for protein folding

What is four tiers? Primary, Secondary, Tertiary, Quaternary

200

The number of protons in an atom

What is the atomic number?

200

A reaction that releases more energy than it absorbs is called this

What is an exergonic reaction?

200

These 4 elements make up 96% of all living matter

Carbon, Hydrogen, Oxygen, Nitrogen

C H O N 

200

This is the pH difference between a pH of 14 and a pH of 12 (Hint: ___x more acidic/basic)

What is 100x more acidic?

200

In DNA, what pairs with adenine?

What is thymine?
300

Atoms of the same element that have different numbers of these subatomic particles are called isotopes.

What is neutrons

300

This is a type of reaction where water is added to break chemical bonds

What is a hydrolysis reaction?

300

In this type of covalent bond, electrons are shared unequally

POLAR covalent bond

300
In a solution, the solute is a substance that does not dissolve in water. It is called...

What is hydrophobic?

300

The primary function of this solution is to minimize pH changes

What is a buffer?

400

An atom has an atomic number of 17 and a mass number of 37. How many neutrons does it have?

20 neutrons

400

These are factors that can affect the rate of reactions or the acctviation energy needed. (Hint: Name at least 2)

What is temperature, pressure, concentration, enzymes/catalysts, reactant properties?

400

All organic compounds contain this element

What is Hydrogen?

400

This is a mixture of water which the particles are medium size, but you still cannot see a visual separation of the molecules.

What is a colloid?

400

This bond joins amino acids together

What is a peptide bond?
500

An atom has 12 protons and 10 electrons. This is the overall charge of the atom

What is +2?

500

What kind of reaction is this? 

AB = A + B

What is a decomposition reaction?

500

This weak attraction occurs between a partially positive hydrogen and a partially negative atom.

What is hydrogen bonding?

500

A solution with a pH of 7

What is a neutral solution?
500

A molecule contains carbon, hydrogen, oxygen, and nitrogen and is made from chains of amino acids. Its three-dimensional shape is essential to its function, and changes in temperature or pH can cause it to lose that shape. 

What is a Protein?
