Cyclohexene is and acceptable IUPAC name whereas hexene is not an acceptable IUPAC name.
It is often useful to be able to anticipate, without doing a detailed calulation, whether an increase in temperature will result in a raising or a lowering of a reaction enthalpy.
Given that the density of air is 740 torr and 27C is 1.145g/l, calculate the mole fraction and partial pressure of nitrogen and oxygen assuming
The rate constant (k) for a reaction was measured as a function of temperature. A plot of ln k versus 1/T (in K) is linear and has a slope of -7445 K. Calculate the activation energy for the reaction
The volume of the base required to neutralize the acid was 47.14 mL. Aqueous silver nitrate was then added to precipitate the Cl- and Br- ions as AgCl and AgBr. The mass of silver halides obtained was 0.9974 g. What are the molarities of HCl and H..
An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295 K, and the volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1mL atm K-1..
If a 1000 kilogram sample of rock is 0.021% gold by mass. How much zinc is needed to react with the gold extracted from the rock?
All of the following are substrates or intermediates in the synthesis of phosphatidylinositol EXCEPT
Iron(III) in water reacts with Hydrochloric acid B. Iron(III) in water reacts with Ammonium Hydroxide Then identify the geometry of the iron(III) complex in water and the complex ions produced in the above reactions
Write a complete mathematical model for a closed system consisting of water only at equilibrium. Be sure to include starting materials, a species list, equilibria (if any), mass balance (if any), a charge balance equation, and other constraints
a 10.0 ml sample of liquid bleach is diluted to 100. ml in a volumetric flask. a 25.0 ml aliquot of this solution is
A sample of sodium reacts completely with 0.426 kg of chlorine, forming 702 g of sodium chloride. What mass of sodium reacted?
The data obtained are 20.36, 19.98, 20.26, 20.18, 19.72, 19.86% Cl. (a) what is the standard deviation of this data. (b) find the 90% and 99% confidence intervals for the percentage of chloride in the sample. Must show work for credit
