Determine the water solubility of the compounds and insert the appropriate state symbols (aq and s) into the chemical equation. Use the solubility rules and the periodic table to help you. Type the correct symbol in each box.

2NaOH( ) + CuBr2( ) → 2NaBr( ) + Cu(OH)2( )

How many moles of gas are present if p=11 atm, v=12l, t=185k?

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.
