The ice record shows a period in Earth's history when there was an ice age and the global average temperature was much colder. During this time, the ice record shows the amount of carbon dioxide in the atmosphere decreased, but the
amount of energy from the sun did not change. How did the the total amount of energy in the Earth system change, how
did this change happen, and how did it contribute to the ice age?

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

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.
