Question: Carbon tetrachloride (CCl4) and benzene (C6H6) form ideal solutions. Consider an equimolar solution of CCl4 and C6H6 at 25°C. The vapor above this solutionis collected and condensed. Using the following data, determine the composition in mole fraction of the condensed vapor.
A piece of metal of mass 18 g at 117 C is placed in a calorimeter containing 48.2 g ofwater at 21C. The final temperature of the mixture is 85.4C.
suppose 321 grams of methylamine (CH3NH2) and 332L of oxygen gas are mixed together in the reaction below at STP. how many grams of water should be prouduced?
Calculate Delta Hrxn for the following reaction- Fe2O3 (s) + 3CO (g)-----> 2Fe (s) + 3CO2 (g). Use the following reactions and given delta H's. 2Fe (s) + 3/2O2 (g)----->Fe2O3 (s), Delta H= -824.2 kJ CO (g) + 1/2O2 (g)----->CO2 (g), Delta H=-282.7 ..
Several artificial nitrogenous bases, called base analogues, can be taken up by cells, converted to nucleotides, and incorporated into nucleic acids. They are often potent mutagens, and some are used in cancer chemotherapy.
