I am working on a Master degree and need to know the following data :
The static (low frequency) dielectric constant of isopropanol at 25 °C
The Optical (high frequency) dielectric constant of isopropanol at 25 °C
Dielectric relaxation time (τ) of isopropanol at 25 °C
Could someone please provide me with these values and a reference or link to a book contains these data?
i am a 12th class student. I have been given a project for finals. Topic is 'Find the standard emf of different samples of urine'. I don't know how to perform the experiment. Please tell me how to do it
methane was burned in an incorrectly adjusted burner. The methane was converted into a mixture of CO2 and CO in the ratio of 99:1, togetherwith water vapour. What will b the volume of oxygen consumed when y dm3 of methane is burned?
The first ionization energy of sodium is 496 kj/mol. Use coulombs law to estimate the average distance between the sodium nucleus and the 3s electron. How does this distance compare to the atomic radius of sodium? Explain the difference.
Please can you tell me the advantages and disadvantages of using these acids as descalers:
-ethanoic acid
-citric acid
-sulfamic acid
and a detailed explanation using in chemistry of how each of these acids remove limescale. Thanks a lot!
