Write down the Dieterici equation of state. Next, determine internal pressure for the Dieterici gas.Justify the form of the expression obtained.
What are the concentrations of HOAC and OAC- in a 0.2M acetate buffer pH 5.0? The Ka for acetic acid is 1.70 X 10-5 (pKa = 4.77).
a balloon is filled with helium to a volume of 25 l at 100kpa pressure and 25degc. the balloon is then released. what
Reductive amination can be used to form primary, secondary, and tertiary amines. Secondary amines are more basic than primary amines due to extra electron donation by the alkyl groups.
the same bulb is placed in a heated oven, and the pressure is measured as 648 mm Hg. What is the temperature of the oven in °C?
Carbon monoxide gas burns in oxygen to form carbon dioxide gas. Write a balanced equation for the reaction and determine the volume of oxygen needed to react completely with 561 mL of CO at 40.0°C and 1.00 atm.
Explain the use of beta-alanine? Is it used as a H+ source, or something else? Why can malonic acid be reacted in V-D modification, while only its ester can be reacted in standard Knoevenagel condensation conditions?
