A 91 gram solution of silver nitrate contains 8 grams of AgNO3. What is the percent by mass of silver nitrate in this solution.
What is the limiting reagent in this procedure? B. Based on your answer to part A, what mass of Fe(C5H5)2 could theoretically be formed? C. A student who carried out this reaction obtained 2.7 g of ferrocene. What was the percent yield for this re..
calculate the difference in mass that is hold by a 500.0mL flask at a temperature of 0.0°C from that at temperature of 20.0 °C? (you can assume the volume of the sample at 0.0 °C temperature =volume of the sample at 20.0°C)
Explain the following observations. 1. Aziridines, compounds that contain nitrogen in a three-membered ring, undergo pyramidal inversion much more slowly than do other alkylamines
If solar radiation is 1200 W/m^2, how many photons strike the leaf every second? Assume three significant figures and an average wavelength of 504 nm for solar radiation.
A solution was made by taking 1.250g of KMnO4 and dissolving it in enough water to make 1.000 liter of solution. This solution was used to titrate H2C2O4·2H2O, a very pure substance. In acidic media, the reaction is.
If 17.2 mL of 0.800 M HCl solution are needed to neutralize 5.00 mL of a household ammonia solution, what is the molar concentration of the ammonia.
The nitro group needs to be taken off as well. I can't seem to find any reference materials on what reagrents can be used. Can you please advise?
