Magnesium carbonate has a ksp value of 6.80×10?6 . What happens when magnesium and carbonate solutions are mixed to give 2.50×10?3 M Mg^2+ and 2.00×10?3 MCO3^2- ?
For each of the following acid-base reactions, calculate the mass (in grams) of each acid necessary to completely react with and neutralize 5.15 of the base.
The reaction previously done was just having trans-cinnamic acid reacted with Br2 forming all the isomers with the double bond being broken and Br put into place.
The problem: CaCO3 can be roasted to produce CaO and CO2. This reaction is carried out in a flash connected to an open-end mercury manometer when the atmospheric pressure is 754 torr
The reaction of 2,2-dimethyl-1-propanol with HBr is very slow and gives 2-bromo-2-methyl-propane as the major product. Give a mechanistic
Write the mathematical expression for the equilibrium constant, Keq, as a function of the concentrations of the products and reactants for this reaction.
Why should you store the crucible plus sample in a desiccator after heating and before weighing? why should you heat the sample to constant mass?
Thermodynamic measurements reveal that ?H° = -66.3 kJ/mol and ?S° = -73.2 J/mole*K at 40°C. What is the equilibrium constant for the binding reaction at 40°C?
