An sewage from a reactor has a combination of ethanol, acetone, and acetonitrile with flow rate of 120 kmol/h, 150 kmol/h, and 30 kmol/h respectively. This combination is to be divided in a phase column at the temperature of 333.15 Kelvin. conclude the range of pressures that this system can exists as 2 phases By imagine Raoult's law is applied to the system
Solid copper (II) hydroxide from copper nitrate. First, add 30 mL of 3.0M sodium hydroxide to the solution in the Erlenmeyer Flask.Take a stirring rod and place the end about 1 cm into the solution; then tough the end to a 2 cm piece of red litmus..
Please note that NO3 has an odd number of electrons. But you must decide where the missing electron will be. Does the central atom violate the octet rule or do the oxygen atoms? Use formal charges to decide.
