Which statement is incorrect for preparing a buret for a titration?
a. on a buret, the zero mark is at the top, so a buret is read from top to bottom.
b. a buret must be clean or liquid will adhere to the inside of the walls of a dirty buret.
c. make sure there are no air bubbles in the tip or stopock of the buret prior to starting a titration.
d. when rinsing a buret, the rinse liquid should be drained through the stopcock.
e. the buret should be rinsed a few times with water before filling the buret with the solution.
i think that your answer would be evaporation
the correct method would be multiplying the speed of light by the time it takes to travel from the moon to earth. this is because:
so= space at the start (origin)
v=speed or velocity
by multiplying miles/second by seconds you get miles as a result.
hope this !
