Bio

chemical compound that releases H+ to a solution

an uneven distribution of charge

the dissolving agent

when water is the solvent

body becomes cooler as water evaporates from it

a liquid consisting of a homogeneous mixture of 2 or more subtances

substance that is dissolved

amount of energy associated w/ the movement of the atoms and molecules in a body of  matter

tendency of molecules of the same kind to stick together

process leading to chemical changes in matter, involving the making/breaking of chemical bonds

weak chemical bond formed when a partially positive H- atom from one polar molecule is attached to the partially negative atom in another molecule

compound that accepts H+ and removes them from the solution

the attraction b/w oppositely charged ions (transfer)

two atoms share one or more pairs of outer shell electrons; strongest bonds

atoms/molecules that are electrically charged as a result of gaining/losing electrons

substance that minimize changes in pH by accepting H+ when that ion is in excess and donation H+ when it is depleted

measures the intensity of heat (average speed of molecules)

measure of Hydrogen ion concentration in a solution

nucleus decays spontaneously giving off particles and energy

• -only one directly involved in chemical activity
• -farther away electron is from nucleus, greater the energy
• -# of electrons in outermost shell determines the chemical properties of the atom

an element that has the same # of protons and electrons, but different # of neutrons (differ in mass)

protons + neutrons

# of protons

smallest unit of matter that still retains the properties of an element

substance that contains 2+ elements

a substance that cannot be broken down into other substances by chemical reactions

measures how difficult it is to stretch/break surface of a liquid

measure of the amount of material in an object

• ionic
• covalent
• hydrogen

anything that takes up space and has mass

even distribution of charge
