During a laboratory experiment, 84.8 grams of iron Ill oxide reacted with an excess of carbon monoxide producing 54.3g of iron. What is the percent yield of iron in this reaction?
Fe2O3 + 3 CO ---> 2 Fe + 3 CO2

dynamic equilibrium is the answer.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

they are all solids.
