The limiting reactant in a reaction: a. has the lowest coefficient in a balanced equation. b. is the reactant for which you have the fewest number of moles. c. has the lowest ratio: moles available/coefficient in the balanced equation. d. has the lowest ratio: coefficient in the balanced equation/moles available. d. None of the above. For choices you did not pick, explain what you feel is wrong with them, and justify the choice you did pick.
CHAPTER ONE: ATOMS MATTER Matter – anything that takes up space and has mass Composed of particles Structure determines the properties Atoms are the building blocks of matter 2+ atoms = molecule Early ideas of matter - Leucippus and Democritus – first to propose the definition of matter - John Dalton – evidence supported Leucippus and Democritus States of Matter Solid - Atoms/molecules pack closely together - Vibrate but don’t move past each other - Fixed volume/shape Liquid - Atoms/molecules pack close but able to move past each other - Fixed volume but no fixed shape - Assume shape of container Gas - A lot of space between atoms/molecules
