Determine the pH of each solution a solution that is 0.028 M in HClO4 and 0.030 M in HCl a solution that is 1.06% HCl by mass (Assume a density of 1.01 g/mL for the solution.)
If the initial concentration of AB is 0.210 M , and the reaction mixture initially contains no products, what are the concentrations of A and B after 70 s
Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating.
Draw the radial probability distribution function of a 8f orbital. And may you please explain what a radial probability distribution is and how to draw one for any orbital? Thank you!
A sports-ultility vehicle has an average mileage rating of 18 miles per gallon. How many galllons of gasoline are needed for a 397-mile trip
The solution was cooled in an ice-water bath for 10 minutes and pure crystals were obtained. The crystals were filtered on a Hirsch funnel and rinsed with about 0.5 mL of ice-cold ethanol. After drying, the weight of the crystals was found to be 5..

Gas was obtained by boiling liquid nitrogen stored in a 175.0 L tank. What volume ofN2 is released at 0.940 atm of pressure and 25 C from a tank full of liquid N2(d=0.808g/mol)
A mixture consists of 323 mg of methane, 165 mg of argon, and 223 mg of nitrogen. The partial pressure of nitrogen at 275 k is 19 kPa.
A equilibrium mixture of H2,I2, and HI at 458C contains 0.110 mol of H2, 0.110 mol of I2, and 0.761 mol of HI in a 5.00 L vessel. What is the equilibrium partial pressure of H2 when equilibrium is reestablished following the addition of 0.100 mol ..
A student weighed 0.0961 g of calcium carbonate (FW: 100.08 g/mol) into a 100-mL volumetric flask, dissolved the powder using nitric acid, and diluted to the mark with 0.2% nitric acid.
