Chlorine dioxide, , is a reddish-yellow gas that is soluble in water. In basic solution it gives and ions. To obtain the rate law for this reaction, the following experiments were run and, for each, the initial rate of reaction of was determined. Obtain the rate law and the value of the rate constant. Initial Concentrations (mol/L) Initial Rate Exp. 1 0.060 0.030 0.0248 Exp. 2 0.020 0.030 0.00276 Exp. 3 0.020 0.090 0.00828

Two friends at different locations want to communicate with each other by sending low energy signals. which of the following methods can they use to communicate? a) produce x-rays using colliding electrons and send them to radios, which capture sound b) send messages using infrared radiation, which travel in the form of waves c) send radio waves through intervening media like radio and television d) produce sound waves using microwaves from heated objects

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
