The temperature at 300 seconds (minutes) is the final temperature of both the metal and the water record to it the nearest 0.1°c in the data table

subtract to find the final temperature changes for the water and the metal

∆T (water)=°c

∆T (metal)=°c

4al + 3o2 → 2al2o3 what does the "3" in front of o2 stand for? a) it indicates that there are 5 oxygen atoms after you add the coefficient and the subscript. b) it indicates that that there are are total of 6 oxygen atoms all bonded together as a single molecule. c) it indicates that there are 3 oxygen molecules chemically bonded to each other in the reaction. d) it indicates that there are 3 separate oxygen molecules in the reaction.
