The students data can be seen here. A chemical reaction clearly took place in the flask. One entry is missing: the mass of the system at the end of the experiment. What amount should be added to the data table? A) 485.68g B) less than 485.68g C) more than 485.68g D) cannot be determined

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
