How to calculate the volume of 1.5M aqueous pottasium hydroxide require to react completly with 2g of benzoic acid and extract the solution twice using the volume calculated?
The temperature of 2.00 moles of Ne(g) is increased from 25 C to 200 C at constant pressure. Calculate the change in the entropy of Neon.
What concentration of glucose will be isotonic with 1.2% CaCl2 solution? Assume a van't Hoff factor of 2.8 for the CaCl2 solution. The molar masses of glucose and CaCl2 are 180.2 g/mol and 111.0 g/mol, respectively.
An 8mL sample of an unknown concentration of NH3 is titrated with HCl. It is found that 12mL of 0.10M HCl is required to reach the equivalence point. What was the concentration of the NH3 in the initial 8mL sample?
The initial DO of the mix is 9.0 mg/L. After 5 days, the DO is 4.0 mg/L. After a long period of time, the DO is 2.0 mg/L, and it no longer seems to be dropping. Assume nitrification has been inhibited so the only BOD being measured is carbonaceous..
The Haber process is used in industry to produce ammonia from N2 and H2. A reactor contains NH3, N2, and H2 at equilibrium at 1000 K. The concentration of NH3 is 0.102 moles/liter, N2 is 1.03 moles/liter, and H2 is 1.62 moles/liter. Calculate the ..
What should the mole percent of oxygen be in the diving gas for the partial pressure of oxygen in the mixture to be 0.21 atm, the same as in air at 1 atm
Draw a titration curve for both of these peptides. Be sure to label the axes properly, indicate the pKa values, the equivalence points and the buffering regions.
explain why a glacial acetic acid in a conductance set-up does forms gradually brighter lights that is dim to bright
The major product of the acid-catalyzed dehydration of heopentyl(2,2-dimethyl-1-propanol) has a different carbon skeleton than that of the starting alcohol
The Born-Haber cycle is a series of steps that represent the formation of an ionic compound from a metal and a nonmetal. For example, the steps in a Born-Haber cycle for the formation of NaCl(s) consist of sublimation of the metal Na atom
