Contrast the term element with compound - ✔✔ANSW✔✔..An element can't be broken
down into simpler substances. A compound is formed from 2 or more elements bonded
together

High specific heat - ✔✔ANSW✔✔..the amount of heat that must be absorbed for 1g of a
substance to change temperature by 1 degree celsius. Water has the ability to stabilize
its own temperature. It can also resist changing temperature by absorbing or releasing
heat. Heat must be absorbed to break hydrogen and vice versa

Heat of vaporization - ✔✔ANSW✔✔..the amount of heat a liquid must absorb for 1 g of
it to turn gaseous. Water requires a high level of heat, because the hydrogen bonds
must be broken before molecules release

Evaporative cooling - ✔✔ANSW✔✔..The property of a liquid where the surface
becomes cooler evaporation , losing highly kinetic molecules to a gaseous state;
contributes to the stability of temperature

Solute - ✔✔ANSW✔✔..The substance that is dissolved

solvent - ✔✔ANSW✔✔..the dissolving agent of the solution, or the dissolver

aqueous solution - ✔✔ANSW✔✔..a solution in which water is the solvent

hydrophilic - ✔✔ANSW✔✔..having an infinity for water, or "liking" it

hydrophobic - ✔✔ANSW✔✔..having an aversion for water, or "fearing" it

molarity - ✔✔ANSW✔✔..a common measure of solute concentration, referring to the
number of moles of elute per liter of solution

, What defines an acid and a base? - ✔✔ANSW✔✔..An acid is a substance that
increases the hydrogen ion concentration of a solution. A base is the opposite. It
reduces the hydrogen ion concentration in a solution.

Why are small changes in pH so important in biology? - ✔✔ANSW✔✔..pH levels in the
environment verify which types of planets and animals species can live in that area.

What is a buffer? Give an example on how they would work in a living organism. -
✔✔ANSW✔✔..Buffers are substances that minimize the changes in the concentrations
of H+ and OH- in a solution. Carbonic and buffers regulate our blood's pH level. It can
give away H+ if there are too many OH- in the blood and vice versa.

What is acid precipitation and why is it important to living organisms? -
✔✔ANSW✔✔..Rain, snow, or fog with a pH lower or more acidic than 5.6. The acid rain
pollutes the environment and slows down growth.

Why is organic chemistry so important in the study of biology? - ✔✔ANSW✔✔..Organic
chemistry is the study of structure, properties, and reactions of organic compounds.
Most reactions in biology are organic and organic chemistry is linked to compounds
produced by living organisms. Biology is the study of life.

What is special about carbon that makes it the central atom in the chemistry of life? -
✔✔ANSW✔✔..Instead of Carbon becoming an ion, it shares its electrons with other
atoms, making it the central point where molecules can branch off. While also holding a
chemical bond.

Structural - ✔✔ANSW✔✔..Differ in covalent partners, have same molecular formula,
differ in arrangement, differ in location of double bonds

Geometric - ✔✔ANSW✔✔..same number and types of atoms and bonds, differ in
spatial arrangements, creates geometric structure

Hydroxyl - ✔✔ANSW✔✔..Also known as alcohols or phenols;it's polar from
electronegative oxygen atoms drawing electrons towards itself; attracts water molecule
helping it dissolve organic compounds like sugars

Carbonyl - ✔✔ANSW✔✔..Also known as ketones or aldehydes; structural isomers with
different properties as for acetone and propanol; making molecules water-soluble; all
sugar molecules have one carbonyl group

Carbon - ✔✔ANSW✔✔..C, + - 4

Hydrogen - ✔✔ANSW✔✔..H, + -1
