Compute the atomic packing factor for cesium chloride assuming thatthe ions touch along the cube diagonals. Ionic radii ofCs+ and Cl- are 0.170 nm and 0.181 nm,respectively
calulate the molarity of acetic acid in a venegar sample knowing that 5.00mL of vinegar requires 43.50mL of 0.105 M NaOH to reach the phenolphthalein endpoint in a titration
A 3.575g sample of a monoprotic acid was dissolved in water. it took 22.67ml of a .1453 M NaOH solution to neutralize the acid. what is the molar mass of the acid
Assume you dissolve .378 g of the weak acid benzoic acid in enough water to make 1.00e2 ml of solution and then titrate the solution with .200 M NaOH.
carbon monoxide binds to hemoglobin 140 times more strongly than oxygen does. what does this tell you about the
Compute the molar mass of the noble gas krypton(Kr) in a natural sample, which is 2.2% 80 Kr (molar mass 79.91 g/mol),
Determine what volume of 1.0 mol/L solution of Copper monosulfide can be made from 23.9 grams of Copper monosulfide?
Why is this isolation so difficult? Please explain using the isoelectric point and the effect PH will have on the structure of your product
How many milliliters of 0.10 M HCl must be added to 44.7 mL of 0.40 M HCl to give a final solution that has a molarity of 0.25 M
Cobalt-60 is commonly used as a source of B-particles. How long does it take for 87.5% of a sample of cobalt-60 to decay, given that the half-life is 5.36 years?
Using active extraction (changing the polarity) and a gravity filtration to remove a component, describe how you would obtain pure naphthoic acid from this mixture.
Which would have a higher energy of activation and why, nitration of 4-bromonitrobenzene or nitration of bromobenzene
Calculate concentrations of H30+ and the pH of each acidic solution. Since HCl is a monoprotic acid, the H30+ concentrations are equivalent to HCl. First do equation: (M con)(V con)=(M dil)(V dil)
