Light waves come in different wavelengths and frequencies. the color of the light we see is dependent on wavelength. when we see a rainbow, we are actually seeing

Which best explains why an iceberg floats?

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

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.
