How would your calculated value for the molecular weight of your unknown been affected (high, low, no effect) if a small quantity of the unknown stuck to the metal stirring rod and failed to dissolve in the benzophenone?
A bomb calorimeter whose components have a heat capacity of 6.66 kJ/°C is filled with 913 g of water. (The amount of water is not constant from experiment to experiment.
Hydrolysis of an ester using sodium hydroxide (2M) is usually a fast reaction. Why would it take almost 40 minutes to complete? It is imperative to consider the location of each reagent within the vial.
Glycolysis and gluconeogenesis are reciprocally regulated at the steps that interconvert fructose-6-phosphate and fructose-1,6-bisphosphate.
If a solid is not completely submerged in the water. Will this technique error increase, decrease, or have no effect on the reported density of the solid. Explain
Calculate the number of moles of solute present in each of the following solutions.
The standard molar enthalpy of formation of ClF3 is -405 kJ. 1/2 Cl2(g) + 3/2 F2(g) → ClF3(g)
Calculate the molality of the unknown compound (m). m=mol of solute X particles per formation / mass of solvent , kg Data given: Mass of test tube , flask, t-butyl alcohol and unknown
The test tube contained some water (besides the metal) that was subsequently added to the calorimeter. Considering a higher specific heat for water, will the temperature change in the calorimeter be higher, lower, or unaffected by this technique e..
If a wheelchair-marathon racer moving at 13.3 miles per hour expends energy at a rate of 635 Calories per hour, how much energy in Calories would be required to complete a marathon race (26.2 miles) at this pace
the use of phenols such as tert-butylcatechol as free-radical scavengers is based on the fact that phenolic hydrogens
The temperature of the calorimeter increases from 19.7C to 20.6C. If under constant volme conditions the heat of combustion of glucose is -2805 kj/mol, calculate the total heat capacity of calorimeter.
The nitration of toluene gives o- and p-nitrotoluene as the major products
