Question- Osmosis is the process responsible for carrying nutrients and water from groundwater supplies to the upper parts of trees. The osmotic pressures required for this process can be as high as 18.6atm. What would the molar concentration of the tree sap have to be to achieve this pressure on a day when the temperature is 22?C?
I need expert help to solve the above question. Show each and every step.
A 32.50-mg sample of naturally occurring elemental silicon was irradiated with neutrons in a nuclear reactor at a flux density of 2.75E-13 thermal neutrons per (cm^2 sec). The activity of 31-Si was determined at a remote site with a beta parti..
What minor product(s) might be expected by this method. Give the detailed reaction mechanism leading to the final product (major). What simple chemical test(s) would help establish that you had, in fact, made the desired alkene product
The product is a cyclopentyl ether (five carbons with an oxygen). Then attached to a carbon directly adjacent to the oxygen is a methyl bromide group.
propose a mechanism for the conversion of glucose 6-phosphate into fructose 6-phosphate by phosphoglucose isomerase based on the mechanism
On the basis of your data what conclusion may be made regarding the separating ablility of simple and fractional distillation? comment on how well your results compare with what might be expected using your actual data below
The solubility of calcium sulfate is 0.67 g/L. Show the calculation of the Ksp for calcium sulfate (all steps including chemical equilibria must be correct for full credit)
assuming that the zinc either reacted with cuso4aq to produce copper or with h2so4aq to produce hydrogren gas h2g
Explain why do we need potassium carbonate before distillation? I did an ethanol from sucrose lab as well as the TA had to put potassium carbonate in the mixture before we utilized fractional distillation to separate the 3 liquids
A lime-soda softening plant treats a flow of 150 MGD, and the water has 86 mg/l CO2. The commercial grade of quicklime has a purity of 85% and the soda ash has a purity of 95%.
Calculate the vapor pressure of a solution made by dissolving 109 grams of glucose
A 8.05-L container holds a mixture of two gases at 39 degree Celsius. The partial pressure of gas A and gas B, respectively, are 0.178 atm and 0.894 atm. If 0.210 mol a third gas is added with no change in volume or temperature, what will the tota..
