question
what are organic molecules
answer
they contain carbon-carbon covalent bonds or carbon-hydrogen covalent bonds. Inorganic do not.
question
examples of inorganic molecules
answer
water and some acids, bases, and salts
question
is water a solute or solvent?
answer
solvent (liquid into which solutes are dissolved)
question
dehydration synthesis
answer
chemical reaction in which water is removed from small molecules so they can be strung together to form a larger molecule
question
hydrolysis
answer
chemical reaction in which water is added to the subunits of a large molecule to break it apart into smaller molecules
question
which molecules are fromed through dehydration synthesis and are broken apart by hydrolysis?
answer
all the major organic molecules
question
what do chemical reactions involve?
answer
energy transfers, as when energy is used to build ATP molecules.
question
what do chemical equations show?
answer
how reactants interact to form products; arrows seperate the reactants from the products
question
water molecules dissociate to form what?
answer
equal amounts of H+(hydrogen ion) and OH- (hydroxide ion)
question
acid
answer
substance that shifts the H+/H- balance in favor of H+; opposite of the base
question
base
answer
substance that shifts the H+/OH- balance against H+; also known as an alkaline; opposite of acid
question
PH
answer
mathematical expression of relative H+ concentration in an aqueous solution
question
pH7
answer
nuetral (neither acid nor base)
question
what are pH values above 7?
answer
basic
question
what are pH levels below 7
answer
acidic
question
when does neutralization occur?
answer
when acids and bases mix and form salts
question
buffers
answer
chemical systems that absorb excess acids or bases and thus maintain a relatively stable pH.
