Trial 1:
Trial 2:

Determine the average percent yield of MgO for the two trials ?

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
