A research supervisor told a chemist to make 100 g of chlorobenzene from the reaction of benzene with chlorine and to expect a yield no higher that 65%. What is the minimum quantity of benzene that can give 100 g of chlorobenzene if the yield is 65%? The equation for the reaction is:
C6H6 + Cl2 -----------> C6H5Cl + HCl benzene chlorobenzene
A gas sample containing N2 and O2 was found to contain 72% N2. If the pressure of the sample was 2.0 atm, what is the partial pressure of O2?
Calculate the equilibrium concentrations of IO3- and Cd2+. Assume volumes are additive, and the temperature remains constant
An aqueous solution was found in a bottle labelled "100. ppm Ca2+ standard." Assuming that 1) all calcium ions in the solution came from calcium carbonate (CaCO3 molar mass is 100.0 g/mol)
When you initially standarized your NaOH sollution, you diluted your HCl stock solution and added water to it. If you used 24.8 ML of 0.18 M HCl stock solution and added another 26.2 mL of water, what is the new molarity of the acid
Imagine that 1.00 mol H2O(l) is placed in a piston with a constant external pressure Pext = 1 bar. The piston is then placed in a large thermal bath at a temperature of 270 K.
An unknown volume of water at 18.2 degrees Celsius is added to 21.6 mL of water at 35.0 degrees Celsius. If the final temperature is 23.5 degrees Celsius, what was the unknown volume
