WILL GIVE BRAINIEST Charlotte completed an experiment in which she investigated and discovered that an electrically charged object can attract an uncharged object without any contact. She used a PVC pipe and small pieces of paper for her experiment. Each time, she rubbed the PVC pipe with a cloth to give it a charge and then held it over the paper. What would be Charlotte's control group in this experiment?
Using the cloth and rubbing it against the PVC pipe
Taking the pieces of paper and rubbing them against the cloth
Not rubbing the cloth against the PVC pipe or the paper
Rubbing the cloth against both the paper and the PVC pipe

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.
