POLARITY
When two atoms share electrons unequally, resulting in a partial positive and partial negative charge, what type of bond is formed?
Polar covalent bond
It is the weakest type of intermolecular force.
London Dispersion Forces
These macromolecules are composed of amino acids and are essential for building and repairing tissues.
Proteins
What is the standard temperature in Kelvin used in gas law calculations?
273.15 K
A reaction where a single compound breaks down into two or more simpler substances.
Decomposition Reaction
Polar molecules attract each other through relatively strong intermolecular forces. What are these forces called?
Dipole-dipole interactions
This strong type of dipole-dipole interaction occurs when hydrogen is bonded to a highly electronegative element like oxygen, nitrogen, or fluorine.
H-bonding / Hydrogen-bonding
These macromolecules are composed of nucleotides and carry genetic information.
Nucleic Acids (or DNA and RNA)
PV=nRT
This reaction involves the replacement of one element in a compound by another element.
Single Displacement (or Single Replacement) Reaction
Why do oil and water not mix?
Oil is nonpolar, while water is polar. / They have different polarities.
It explains the ability of some insects to walk on water.
Surface Tension
Triglycerides, phospholipids, and steroids are all examples of this type of macromolecule.
Lipids
Boyle's Law describes the relationship between which two gas priorities?
Pressure and Volume
A chemical change that releases energy in the form of heat and light.
Exothermic Reaction
What is the term for a molecule that has a partial positive charge on one end and a partial negative charge on the other?
Dipole
N, O, F
This monosaccharide is the primary source of energy for most living organisms.
Glucose
What law states that the volume of a gas is directly proportional to absolute temperature when the pressure is held constant?
Charles' Law
A substance that speeds up a chemical reaction without being consumed itself.
Catalyst
Polarity in a bond arises from a difference in this property between two atoms. What is this property?
Electronegativity.
Glycogen in animals and starch in plants are both examples of storage forms of this macromolecule.
Carbohydrates
Gay-Lussac's Law describes the relationship between pressure and which other gas property, when volume is held constant?
Temperature
The principle that states that matter cannot be created or destroyed during a chemical reaction.
Law of Conservation of Mass
