When performing your experiment, you add your first drop of oleic acid/benzene solution, and a lens forms immediately. What is wrong with your setup
Mercaptoacetic acid and NH3 were introduced, production of the complex with the former resulted in the release of an equivalent amount of EDTA, which required a 22.85-mL titration with 0.07238 M Mg2+. Calculate the percent Cu and Ni in the alloy.
an empty flask has a mass of 123.4 grams. when the flask is filled with water, the mass is 211.6 grams. if 10 grams of zinc (density=7.14g/cm3) are added to the flask filled with water, what is the new mass of the flask?
Calculate the magnitude of the current in amperes if the number of moles of hydrogen gas produced is 5.99×10?4 .
An unknown metal chloride has the formula MClx. The addition of 28.9 mL of 0.432 M aqueous lead (II) nitrate to 26.7 mL of 0.311 M aqueous MClx causes all the lead ions and chloride ions present in solution to precipitate out as lead (II) chloride
By comparing the Charles's law equation to the linear equation, y= -0.171x + 46.837, where y is volume and x is temperature, determine the value of k.
