When 5.00g of Al2(SO4)3 * 18H2O are heated until it dehydrates how many grams of water are produced
Why is acceptable to use a mixture of the alpha and beta anomers of D-(+)-mannose in this reaction? (i.e. why isn't it necessary to use either a pure alpha or the pure beta anomer? 2. What is the role of ferric chloride?
For example if your compound is water and you have the information the boiling point, Tb=(99.98 C), the enthalpy of vaporization= (40.65 kJ/mol) and the molar mass= 18.02g/mol.
A 100.0 g sample of water at 90.°C is added to a 500.0 g sample of water at 10.°C. Calculate the final temperature of the water.
Hydrogenation of a liquid triacylglycerol converts: a. the ester group to a ketone group, b. the ester group to a carboxylic group
How much heat is required to warm 225 g of ice from -44.1°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C?
Consider the titration of 50.0 mL of 0.200 M HClO4 by 0.100 M NaOH. Calculate the pH after 37.7 mL of NaOH has been added.
Construct a Molecular Orbital Diagram showing the various energy levels for an Octahedral Transition Metal Complex (?-bonding only case!). Label (i) all initial metal orbitals
Molar mass has the units of grams/mole. Molar mass serves as a conversion factor between numbers of moles and mass. If you know how many moles you have, you can calculate their mass; if you know the mass of a sample, you can calculate the number o..
Diethylamine, (C2H5)2NH, is a weak base (pKb=3.16 at 25oC). What is the pH of 0.155 mol/L (C2H5)2NH(aq) at 25oC? Give your answer accurate to two decimal places.
