Why is there a concern for dissolved organics and color in the water supply and in water treatment plant?
show how you would synthesize di-tert-butyl ether from any starting material you would like that contains four or fewer carbons
Describe the method for checking for completeness of precipitation. Why are precipitates usually rinsed with distilled water before they are tested further.
At pH=7, do you expect the following peptides to bind a cation exchanger or an anion exchanger resins
Write a mechanism for the reaction of an alkyl halide with alcoholic silver nitrate which demonstrates the type of substituition which occurs. Explain how this mechanism accounts for the relative rate of reactivity for 1 degree, 2 degree and 3 deg..
If a sample of 0.059 g KHP requires 30.21 mL of NaOH to titrate it, what is the molarity of NaOH
The normal freezing point of water is 0.0C. at this temperature the density of liquid water is 1.000 g/ml and the density of ice is 0.917 g/ml. The increase in enthalpy for the melting of ice at this temperature is 6010 J/mol.
The observed melting point of camphor is often low. Look up the molal freezing point depression constant K for camphor and calculate the expected depression of the melting point of a quantity
If the vapor pressure of PCl3 gas above the liquid were 0.085atm at 30 degrees Celsius, would you expect the reaction to proceeds towards more evaporation or would you expect condensation of gas into liquid
The gas expands at constant temperature to a final volume of 15.5 L. Compute the new pressure.
Determine the pH of a solution with .12M of sodium acetate at 25 degrees C. Ka=1.8x10^-5
Discuss how Dalton's Atomic Theory defines the Law of Definite Proportions as well as the Law of Multiple Proportion by taking the instance of two oxides of carbon. You may opt for any other suitable example.
If in a decompositionreaction, one sample of magnesium fluoride produced 1.66kg of magnesium and 2.58kg of fluorine. A second sample produced 1.27kg of magnesium.How much fluorine (in grams) did the second sample produce
