Explain how much CO2 is dissolved in water at 500ppmv at 15 C? Explain what is the dissolved CO2 equivalent to in the dissolved phase?
An oxalic acid solution contains the subsequent species in varying concentrations- C2H2O4,C2HO-4,C2O2-4, and H+. Depict Lewis structures of C2HO-4, and C2O2-4. Which of the above four species can act merely as acids which can act only as bases, ad..
If a 25.0 mL sample of sulfuric acid is titrated with 50.0 mL of 0.200 M potassium hydroxide to a phenolphthalein endpoint, what is the molarity of the acid? H2SO4(aq) + 2 KOH(aq) ? K2SO4(aq) + 2 H2O(l) Answer 0.300 M 0.200 M 0.150 M 0.400 M 0.100..
A Researcher reads directions that call for addition of 25.0 mL of anhydrous ethanol (ethyl alcohol). From among the bottles in the lab, which one should she select
Mehtanol-water solutions behave as essentially ideal solutions (the activity coefficients which measure deviation from ideality are equal to or close to one).
If you look at a reaction equation for an esterification reaction, you cannot tell where the oxygen comes from (acid or alcohol). Knowing the mechanism of this reaction, devise an experiment using O18, to help prove unequivocally where the oxygen ..
A sample of nitrous oxide gas, N2O in a nonrigid container at a temperature of 33C occupies a certain volume at a certain pressure. What will be its temperature in degree Celsuis in each of the following situations
A 15.0 g piece of iron (Cp = 25.09 J/mol-C) is heated to a temperature of 47.0 ?C and then placed in contact with a 275 g piece of copper at 20.0 ?C (Cp = 25.46 J/mol-C). What was the final temperature of the two pieces of metal?
A dissimilar sample of Compound X in the same solvent has an absorbance of 0.506 at 528 nm when measured with the same cuvet. Explain what is the concentration of this second sample
Here it is. Analysis of several samples of a material containing only iron and oxygen gave the following results. Could these samples be the same compound
Another experiment shows that vitamin B6 is made up of 14.89% N. What is the simplest formula for vitamin B6. The answer should be C17H20N4O6.
For a certain experiment, R-140a vapor is contained in a sealed glass tube at 20 degrees celcius. We want to know the pressure at this condition, but there is no means of measuring it since the tube is sealed
If a second experiment is done with half as much H2O2 as the experiment in question 1, and the solution turns blue in 180 seconds, what is the order of the reaction with respect to H2O2?
