Particular anion can be "positively identified" if the presence of that anion is indicated by a reaction that cannot be confused with any other reaction and that cannot be masked (hidden) by any other reaction occurring at the same time. suppose that a solution contains four anions: chloride, nitrate, nitrite and sulfate. which anions can be positively identified

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
