100
Positively charged particle inside an atoms nucleus.
What is a proton?
100
Formed when atoms share one or more pairs of electrons.
What is a covalent bond?
100
Type of molecule that has regions with slight electrical charges due to uneven pull on electrons. This gives water the ability to dissolve things.
What is a polar molecule? (Polarity)
100
Compounds that contain Carbon are considered to be this
What are organic compounds?
100
The amount of energy needed to break a bond, or the amount of energy released when a bond forms.
What is bond energy?
200
Has no electrical charge.
What is a neutron?
200
Forms between oppositely charged ions due to electrical attraction.
What is a ionic bond?
200
When water molecule "stick" to each other.
What is cohesion?
200
The monomers are monosaccharides and polymers are polysaccharides.
What carbohydrates?
200
When reactants and products are formed at the same rate, a reaction is at equilibrium.
What is chemical equilibrium?
300
The smallest basic unit of all matter.
What is an atom?
300
Attraction between slightly positive H+ atom and slightly negative atoms.
What is a hydrogen bond?
300
When water molecules "stick" to other substances.
What is adhesion?
300
Composed of monomers called amino acids.
What are proteins?
300
The amount of energy that needs to be absorbed to start a chemical reaction.
What is activation energy?
400
Made of atoms of two or more elements bonded together.
What is a compound?
400
This is the bond that links amino acids together.
What is a peptide bond?
400
Substance present in the greatest concentration; dissolves other substances.
What is a solvent?
400
Phospholipids are a type of polymer of this macromolecule that is essential in cell structure.
What are lipids?
400
A reaction when more energy is released than is absorbed.
What is an exothermic reaction?
500
Atoms that gain or lose electrons are considered to be this
What is an ion?
500
Carbon forms (blank) bonds with up to four other atoms.
What are covalent bonds?
500
Measures the amount of H+ ions in a solution.
What is pH?
500
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are two types of this macromolecule.
What are nucleic acids?
500
Can increase the rate of reactions without increasing the temperature and are greatly affected by pH and temperature changes.
