Consider the combustion of ethane:
2C2H6 + 7O2 yields 4CO2 + 6H2O
If the ethane is burning at the rate of 0.1 mol/L*s, at what rates are CO2 and H2O being produced?
Thyroxine, an important hormone that controls the rate of metabolism in the body, can be isolated from the thyroid gland. If 0.455 g of thyroxine is dissolved in 10.0g of benzene, the freezing point of the solution is 5.144 degrees celcius.
