Suppose 1.2 M NaOH is used to titrate a 280.0 mL solution of 0.88 M hydrochloric acid (HCl), explain what volume of base is required to reach the equivalence point of the titration?
certain temperature and pressure, one liter of CO2 gas weighs 1.85 g. What is the mass of one liter of CH4 gas at the same temperature and pressure?
The atomic radius of nickel is 124 pm, and the average mass of nickel is 58.6934 amu. How do I calculate the density of nickel assuming that it is simple cubic, then body-centered cubic, and then face-centered cubic cell structures.
A student traces of brown deposite during the KMnO4 (NH4)2Fe(SO4)2 titration and quickly add more H2SO4 and continued his titration?Suggest what wil happen and why.
An experiment is performed on an unknown material and produces the following heat curve. The temperature of the material is shown as a function of heat added. If the sample of material has a mass of m = 9.80 g, calculate the specific heat when thi..
A gas is expanded in a cylinder from 2.00 L to 12.0 L against an external pressure of 1.80 atm. At the same time, it absorbs 2.56 x 103 J of heat from the surroundings. Calculate ?E of the gas in J. (1 L•atm = 101.3 J)
The mean free path is the average distance a molecule will travel before colliding with another molecule. From kinetic gas theory (which is explained in any pchem text and probably some general chem texts as well if you're curious),
Can someone please draw the scheme of Selenium: "A sample is preserved in the field at 4oC. The sample aliquot is oxidized, in acidic persulphate
A 0.9092-g sample of wheat flour was analyzed by the Kjeldahl procedure. The ammonia formed was distilled into 50.00mL of 0.05063 M HCl; a 7.46-mL back-titration with 0.04917 M NaOH was required. Calculate the percentage of protein in the flour.
