smallest particle of an element. basic building block of matter.
cannot be broken down into simpler substances. made up of 1 type of atom.
consisting of 2 or more different elements. can be seperated in simpler substances by a chemical reaction.
shows a chemical reaction. (reactants "need" left, products "produce" right). Cannot destroy or create matter. matter is rearranged.
combination of substances that do not combine chemically. can seperate.
mixture in which one or more substances (solutes) are distributed even in another substance (solvent).
Most important inorganic solvent?
substance the releases hydrogen ions (H+) in a solution. (ex. hydrochloric acid)
release hydroxyl ions (OH-) in a solution (ex. NaOH)
a scale that goes from 0 to 14, 7 being neutral that determines how acidic or basic and substance is. (ex. 3= very acidic, 13= very basic)
substance that shows the prescense of another substance by changing color (ex. phenolphthalein)
the process in which water is added to breat a bond in order to create smaller molecules
removal of water to create a new bond in order to build a larger molecule
made up of C,H, and O. Source of energy for respiration.
simple sugar, one, ex. glucose
2 monosaccrides bonded together, ex. sucrose (table sugar)
do not contain both carbon and hydrogen. (ex. H2o, CO2)
contains both carbon and hydrogen together.
four organic compunds
3.nucliec acids (DNA + RNA)
"building block", one unit, many of these make a polymer (ex. glucose)
many monemers connected together by bonds. big molecule of repeating units. (ex. starch)
complex carbohydrates, 3 or more
found in plant cells (cell wall)
animals storage of carbs sotred in liver and muscle cells.
