A solution is made by dissolving 5.2246g of EDTA in 4.0000 liters of DI water. Assuming the EDTA was dried at 80°C and it still contains 0.3% excess moisture, calculate the EDTA molarity. (0.003499M)
If someone can go in depth into finding the Ka to this and then guiding me through the rest of the steps, I'd be eternally grateful
Describe the development of the modern periodic table. Include contributions made by Lavoisier, Newlands, Mendeleev, and Moseley.
While 1.22 g of a white solid, supposed of being pure cocaine, a molecular compound, is dissolved in 15.60 g of C6H6 the freezing point is lowered by 1.32 ¬0C. Compute the molar mass of the solid. Kf value for benzene = 5.12C/m.
Consider the molecules ClF3O and BrF3O. (a) Would expect the lone pair on the central halogen to be axial or equatorial in these molecules? Explain
In one experiment, 22 g NH3 was used to react with excessive O2 and produces 30.4 g of water, what is the percentage yield of this experiment?
suppose 1.5 mol of methane is allowed to react with 4 mol of oxygen. what is the limiting reagnant?
balanced equation for the preparation of the diazonium ion that i have made. draw possible structure for the azo dye.
The standard reduction potential for the reduction of Eu3+(aq) to Eu2+(aq) is -0.43V. Which of the following substances is capable of reducing Eu3+(aq) to Eu2+(aq) under standard conditions?
Calculate the equilibrium constant (Keq) for the reaction of equimolar amounts of acetophenone and sodium hydroxide to generate the enolate.
You may use expanded, condensed, or line structures, provided they are neat and legible. If you could not identify one of your components, then pick an appropriate component from the list of unknowns.
A chemist wants to make 5.5L of a 0.280M CaCl2 solution. What mass of CaCl2 (in g ) should the chemist use?
A solution of H2SO4 and KI is then added to conver the MnO2 to MN^2+, and the iodide is converted to I2. The I2 is then titrated with standardized Na2S2O3. Calculate the amount of O2 in 25.0mL of water if the titration requires 2.45ml of 0.0112 M N..
