A liquid with a density of 40.0 lb/ft^3 flows through a long pipe of circular cross section at a rate of 200 ft^3/hr.
Determine if the flow is turbulent or streamline under the following conditions:
A) when the inside pipe diameter is 2.0 inches and the absolute viscosity of the fluid is 1.8lb/(hr)(ft)
B)when the inside pipe diameter is 1.2 ft and the absolute viscosity of the fluid is 3.0cP.
Write a hypothetical inner-sphere redox mechanism for the reaction of [Cr(H2O)6]2+ with cis-[Co(NH2CH2CH2NH2)2I2]+ (aq) in acid solution to give (ultimately) cis-[Cr(H2O)4I2]+, Co2+(aq), and [NH3CH2CH2NH3]2+."
What would you observe if Cu2+ and Bi3+ was treated with 6M NHO3 rather than concentrated NH3
potassium hydrogen phthalate is a monoprotic acid. Dihydrogen phthalate(H2C8H4O4) is a diprotic acid. An analyte sample contains 0.127 M KHP and 0.0678 M H2C8H4O4. What volume of a 0.205 NaOH solution is required to neutralize 25.0mL of the analyt..
