Copper react with oxygen to form two oxides x and y. on analysis, 1.535g of x, yield of 1.365g of copper and 1.450g of y yield 1.160g of copper. determine the chemical formula of x and y. which of the laws of chemical combination is illustrated above.

Identify the electromagnets with poles that are reversed from the electromagnet shown above

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.
