Create a pH-log concentration plot for carbonate and acetic acid for total concentrations of 10-3 and 10-4, respectively. Discuss the relative importance of the various species as a function of pH and how the plot relates to the dissociation constants of the acids
A 10 mL sample of a solution of Pb(ClO3)2 was diluted with water to 21 mL. A 10 mL sample of the dilute solution was found to contain 0.021 moles of Pb2+. What was the concentration of Pb(ClO3)2 in the original undiluted solution?
A 0.0355 g sample of an unknown molecular compound is dissolved in 1.000 g of liquid camphor at 200.0°C. Upon cooling, the camphor freezes at 157.7°C. Calculate the molar mass of the unknown compound.
A mixture contains both potassium phosphate and potassium chloride. What is the percentage of potassium phosphate in this mixture if reaction of 0.401g of this mixture with excess copper (II) chloride yields 0.213g of copper (II) phosphate?
what is the mole fraction of each componet in solution? ethanol, methanol, water.
Write out the chemical equation and the equilibrium constant expression based on the concentration.
draw the molecule by placing atoms on a grid and connect with bonds for when the cyclopentane is exposed to Br2 in presence of light.
