(d) 150.0 mL
(f) 250.0 mL
A piece of amber was cut into a rectangular solid measuring 5.18cm by 10.8cm by 2.85m . What is the volume in cubic centimeters
Calculate the number of moles of cyclopentadiene and maleic anhydride which you will use in your experiment. Explain why we use excess of cyclopentadiene and do the reaction at 0 °C?
a saline solution contains 150 mEq/L each of Na+ and Cl- how many moles of Na+ and Cl- are in 2.50L of the solution
Lead(II) sulfide was once used in glazing earthenware. It will also react with hydrogen peroxide (H2O2)to form lead(II) sulfate and water. How many grams of hydrogen peroxide are needed to react completely with 265 g of lead(II) sulfide?
My dilemma is that I'm unsure on how to find the actual limiting reactant, and what information I should use. There's too much given; but from my introspection, we only need 1-Octene and the Pt catalyst
The transmittance of the mixture was read and compared to a calibration curve which indicated a concentration of I3^- as 5.52*10^-4 M. Calculate the following: c.) The concentration in moles/L of IO3^- in the original sample.
