Question- A solution is 0.012 M in Pb(No3). Solid Na2SO4 is added until a precipitate of PbSO4 just begins to form. Calculate the concentration of sulfate ion at this point
As soon as possible please provide complete computation of the above problem
how many grams of ammonium sulfate can be produced in 30 mol of h2so4 react with excess nh3 according to the equation
Standard Temperature Pressure and Volume, The respiratory rate of a person is 20 breathes per minute. If every average breath is about 310cm^3 of air at 22C and 740mmHG
Problem- Calculate the value of the equilibrium constant for the balanced net ionic equation for CH3COOH(aq) + OH^- ---> CH3COO^- + H2O
What is the resulting pH when 0.005 moles of KOH is added to 0.100 L of a buffer solution that is 0.100 M in H2PO4 - and 0.100 M HPO4 2- and the Ka2 = 6.2 x 10^-8
Suppose that a 4.0 L sample of gas at 1.0 atm is heated from 44°C to 53°C, during this process the volume doubles. What will the final pressure of the gas sample be
Calculate the work associated with the compression of a gas from 121.0L to 80.0 L at constant pressure of 20.7 atm.
Calculate the volume of 50 wt% NaOH solution needed to be diluted to 1 liter in order to make 1 liter of 0.1 M NaOH. Assume the density of 50 wt% NaOH is 1.5 grams of solution per mL of solution.
This buffer is to be prepared by mixing 25.0 mL of 0.1 M HCl with the correct mass of solid sodium acetate. You will determine the mass of solid sodium acetate needed.
