Define the differences observed in the IR and NMR spectra of the starting material (p-anisaldehyde and acetophenone) and product (trans-p-anisalacetophenone) that are reliable with the formation of the latter in the experiment of synthesizing trans-p-anisalacetophenone from p-anisaldehyde and acetophenone.
calculate the final temperature of the gas mixture. Assume the heat capacities of the gases are constant and are given in Appendix B of your text.
if 0.500 g of antacid was added to 50.00 ml of 0.100 m hcl and 5.65 ml of 0.100 m naoh was required to titrate the
An enzyme reaction, in 2ml of 0.08 M of an acetate buffer, pH=4.76. During this reaction 2micromol H+ was produced
If you have 430.0 mL of water at 25.00 °C and add 120.0 mL of water at 95.00 °C, what is the final temperature of the mixture. Use 1.00 g/mL as the density of water.
An inexpensive hygrometer often used by cello players in Minnesota is based upon the color changes of cobalt(II)chloride as the relative humidity of the atmosphere changes.
The third ionization energy of Ru is less than the third ionization energy of Fe. Explain.
The united states food and drug administration requires that any product called vinegar contain at least 4% of weight by acetic acid .Assuming that the density of vinegar is the same as water, does this satisfy the FDA requirement to be called vin..
When a 5.00 L flask containing 1.35 atm of gas A is joined with a 2.00 L flask containing 1.00 atm of gas B, and the stopcock between the flasks is opened, and the gases are allowed to mix thoroughly at constant temperature
What is the density of an object with a weight of 32 grams if it has a volume of 4 cubic centimeters
Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 and 1.00 ] and that no heat is lost to the calorimeter itself, nor to the surroundings.
Determine theoretical yield, limiting agent and excess reagent - How much excess reagent remains after the reaction goes to completion
The first-order rate constant for the decomposition of C2H5Cl, C2H5Cl(g) C2H4(g) + HCl(g) at 27 oC is k = 7.27e-30 s-1. Suppose we start with 0.0813 mol of C2H5Cl in a volume of 6.0 L. How many moles of C2H5Cl will remain after 2.20e+27 min
