Student A conducted the acid-catalyzed dehydration of ethanol at 180 degrees C and obtained a gaseous product. Student B conducted the same experiment at 140 degrees C and obtained a low boiling liquid. Draw mechanisms for the formation of the products for both reactions.
Why is the theoretical maximum final temperature reached by the water in a calorimeter always slightly higher than the highest recorded temperature
The reaction of water and coal at a high temperature produces a mixture of hydrogen and carbon monoxide gases. This mixture is known as synthesis gas (or syngas). What mass of hydrogen gas can be formed from the reaction of 51.3 g of carbon with e..
Inorganic phosphorous is spectrophotochemically measured in blood serum by formation of a reduced heteropoly acid (heteropoly blue) and comparison of its absorbance with a standard treated by the same procedure.
