A bunsen burner uses the combustion of butane (c_4_H_10_) as a means to provide heat. If during a laboratory experiment the class uses 875 grams of butane. how many grams of each product will be produced?
Which of the following compounds would you expect to be ionic?
C2H5OH(l) + C3H7COOH(l) C3H7COOC2H5(l) + H2O(l) Determine the mass of ethyl butanoate produced if 3.30 mol of ethanol is used.
Calculate the percent manganese in the sample as Mn3O4 (only part or none of the manganese may exist in this form, but we can make the calculations on the assumption that it does)
An aqueous CaCl2 solution has a vapor pressure of 82.1 mmhg at 50 C . The vapor pressure of pure water at this temperature is 92.6 mmhg What is the concentration of in mass percent?
When making a plot with the Claussius Clapeyron equation, the enthalpy of vaporization can be calculated from the slope of the line of lnP vs 1/T.
5.00 mL of water sample was titrated for hardness with 4.15mL of 0.0200M EDTA. write the equastion for the reaction and calcualte the hardness of the water in ppm
A buffer solution is prepared by dissolving 1.51 g NH3 and 3.85 g (NH4)2SO4 in enough water to make 0.500 L of solution.
When NH3 is prepared from 28 g N2 and excess H2 the theoretical yield of NH3 is 34 g. When this reaction is carried out in a given experiment, only 30. g is produced.
This question deals with the reaction between benzene and 1-chloro-2-methylpropane in the presence of AlCl3. Knowing that the arenium ion intermediate has positive charge on the ortho and para carbons
Label and identify ALL functional groups. Label the chiral carbons (*), label the priorities (1,2,3,4) of the four "things" connected to the chiral carbon, draw the arrow or rotation and identify as R or S.
The distance between layers in a crystal is 281 pm. X rays are diffracted from these layers at an angle of 19.0°. Assuming that n = 1, calculate the wavelength of the X rays in nm.
Calculate the change in pH when 6.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq)
