Suppose 68 g of carbon monoxide is reacted with 8g of hydrogen gas to produce methanol (chemical formula CH3OH or CH4O)
a) Calculate the theoretical yield of methanol.
b) If 3.57 x 10^4 of methanol is recovered, what is the percent yield of methanol.
How many moles of NaOH must be added to 1.0 L of 1.2 M HC2H3O2 to produce a solution buffered at each pH
Describe how you would prepare 1.000 L of 0.05M HEPES buffer @ pH 7.45 in the lab. You have pure HEPES, a pH meter, 1.00 M HCl and 1.00 M NaOH, and all of the pure water and glassware you need.
Problem- The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate and the other half still remains unreacted. If 0.360 moles of a monoprotic weak acid (Ka = 4.5 Ã- 10-5..
32.5 kJ/mol°GD Muscles are powered by the hydrolysis of Adenosine tri phosphate determine Keq for this reaction
Compare the results of your calculations from 2 and 4 above with the actual molarity of the Ba(OH)2 solution. Which method of analysis, equivalence point or gravimetric determination, was more accurate in your experiment. Why
Products at Home Containing Organic Molecules, Find two or more products in the home that contain organic molecules. From these products, make a list of 10 organic compounds present in the products.
The half -life of 14C is 5730 years. A sample taken for radiocarbon dating was initiate to contain 56 percent of its original 14C. Explain what was the age of the sample. The decay follows first order kinetics.
One of the differences between a voltaic cell and an electrolytic cell is that in an electrolytic cell,
