when a .28 gram sample of limestone was decomposed by heating 75 millileters of CO2 at 750 mm Hg and 20 degrees celcius were evolved. How many grams of CO2 were produced?
explain why there is a difference in spectrophotometric response during titration before and after the equivalence point by placing the statements below into the appropriate categories.Now, calculate the concentration of apotransferrin present in ..
For the following reaction, Kc = 0.513 at 500 K . N2O4(g) 2NO2 (g)
An indicator has a pKa of 5.7 . It is colorless in acid solution and deep green in alkaline solution.
Molecular chlorine and molecular fluorine combine to form a gaseous product. Under the same conditions of temperature and pressure it is found that the volume of Cl2 reacts with three volumes F2 to yield two volumes of the product.
Choose the process from below which describes a change which is dependent on the path by which the change occurs. The heat generated by a chemical reaction carried out at constant temperature and pressure.
