Alpha helices are a type of secondary structure in proteins. What is the length of a 23-kDa single-stranded ?-helical protein segment? Assume a mean residue mass of 110 Da.
Compute the molarity of the hydroxide ions (OH- )in a solution that has been made by adding 70.3 grams of barium hydroxide (Ba(OH)2) in H2O(water) and diluting the solution to a final volume of four litres.
What is the pH of the resulting hydrochloric acid solution? Part B 0.75g of sodium hydroxide (NaOH ) pellets are dissolved in water to make 4.5L of solution. What is the pH of this solution?
If 37.3 g of CO2 is produced in the reaction of C2H2 with O2 to form CO2 and H2O, how many grams of H2O are produced in this reaction.
tripling the concentration of A increases the rate by a factor of 27, doubling the concentration of B has no effect on the rate, and tripling the concentration of C increases the rate by a factor of 3. Write down the rate law for this reaction.
The EPA limit for lead in the water supply is 15 parts per billion by mass. Calculate the number of lead ions present in 1.00 kg of water that is at the EPA limit for lead.
What is the maximum mass of ammonia that can be produced from a mixture of 155.3 g of N2 and 35.98 g of H2? 2. Which element would be left partially unreacted? (enter nitrogen or hydrogen)
Vinegar is an aqueous solution of acetic acid. By law, it must contain 4 g acetic acid per 100 ml solution. What approximate volume of 0.10 M of NaOH would be neededto titrate a 15.00 ml aliquot of commercially availabe vinegar?
Consider the titration of 88.0 mL of 0.146 M Ba(OH)2 by 0.584 M HCl. Calculate the pH of the resulting solution after the following volumes of HCl have been added.
A light green liquid, and informed that someone accidentally spilled a few small flecks of an intensely green-colored crystalline dye in a rather expensive solvent, so it doesn't make sense to throw away the very slightly contaminated solvent.
If the initial concentration of HD(g) is 8.433 mol/L, calculate the % of HD(g) left over after the reaction reaches equilibrium according to the balanced equation. The value of Kc at -173.0 °C is 0.52. The initial concentration of the reaction pro..
When 37.6 ml had been added the solution turned red .How many milligrams of I- were present in the original solution?
Conductivities are often measured by comparing the resistance of a cell filled with the sample to its resistance when filled with some standard solution, such as aqueous potassium chloride. The conductivity of water is 76 mS m^?1 at 25°C
