Question: The equation for the decomposition of silver oxide is 2Ag2O=4Ag+O2.Set up a ratio to calculate the number of oxygen molecules released when 1 g of silver oxide is broken down.
A sample of steam with a mass of 0.552 g and at a temperature of 100 degrees C condenses into an insulated container holding 4.50 g of water at 6.0 degrees C. Assuming that no heat is lost to the surroundings, what will be the final temperature of ..
In the acid-catalyzed dehydration of cyclohexanol, the mechanism requires only catalytic acid, but in the experiment we used large excess.
