How high must a waterfall be for the water to change temperature by 0.1K during its fall (assuming no evaporation)?
Explain how the yield of reaction can be greatly increased (meaning reactants are more extensively converted into products) by applying Le Chatelier's principle.
The molar mass of cellulose is approximately 6.0 x 10^5 g/mol and the molar mass of a soluble starch is on the order of 4.0 x 10^3 g/mol. The monomer unit in both of these molecules has the emperical formula C6H10O5.
