How many joules of heat energy would be needed to raise the temperature of 125 grams of water from 22.0° c to 57.0° c? the specific heat capacity of liquid water is 4.18 j/ (°c × g).

Agood hypothesis includes which of the following? a: prediction b: data c: uncertainty d: conclusion

Apiece of metal with a length of 1.42 cm was measured using four different instruments. which of the following measurements is the most accurate?

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.
