H+ = 1 x 10 ^-7 what is the pH?
7 *ph is equal to exponent
What is the equation to convert from one unit to another?
given unit x
desired unit/given unit
ex: 20m to millimeters
20m x 1000mm/1m = 20,000mm

type of microscope that uses a series of lenses and a light source
compound light miscroscope
type of microscope that is used to view objects in 3 dimensions
steroscopic microscope
type of microscope that filters out certain light rays to view certain structures better (especially clear objects)
phase-contact microscope
type of microscope that shines a beam of electrons across the surface of an object in a vacuum that gives an image of surface and dimensions of an object
scanning electron microscope
type of microscope that uses electrons in a vacuum to view ultra-thinly sliced objects that have been treated with heavy metal salts to imporce contrast
transmission electron microscope
