Calculate the distances NH3 gas and HCl gas would travel in this experiment if a 100.0-cm tube were used, based on the accepted molar masses for the two gases
The student next added 3M KOH solution to the aqueous solution and Mg(OH)2 precipitated. After filtering the solution and drying the precipitate, the student recovered 1.10g of Mg(OH)2. Calculate the percent Mg(OH)2 in the mixture
500.0 mL of 0.160M solution of H3PO4 is combined with a 300.0 mL of a 0.245M solution of Ba(OH)2. What is the maximum mass of solid Ba3(PO4)2 that can be collected
Methane, CH4, burns in oxygen gas to form water and carbon dioxide. What is the correct balanced chemical equation for this reaction
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 ..
A sample of an unknown gas effuses in 11.9 min. An equal volume of H2 in the same apparatus at the same temperature and pressure effuses in 2.00 min. What is the molar mass of the unknown gas
What is the FORMULA for the limiting reagent? What is the maximum amount of carbon dioxide that can be formed in grams? What amount of the excess reagent remains after the reaction is complete in grams?
the triangleG and triangleG0! both refer to the free energy change in the steady state reaction. steady state means that the concentrations of substrates and products are fixed or constant. all of the following statements about triangleG and trian..
If the hydrolysis to the diacid is not complete, how could you separate the desired diacid from the unhydrolyzed anhydride by extraction. Discuss the chemistry involved.
Hydrogen bonds a) play an important role in the solvent properties of water b) are not involved in protein structure c) play a role in the properties of DNA, but not of RNA d) give water a lower boiling point than expected 44
If you dissolved 0.95g of salt in 100ml distilled water, what is the concentration of salt in this solution in g/ml
An opened can of soda goes "flat" because the partial pressure of carbon dioxide is lower in the atmosphere than in the unopened can. Fish kills may occur in the summertime because an inadequate amount of oxygen is dissolved in the water. A soluti..
