Suppose argon gas at a partial pressure of 113 Pa is in equilibrium with water at 30o-1)oH-1-1C. Calculate the concentration of Ar(aq) in the water ( mol L. For argon at 30C, K = 0.0010 mol Lbar.
Carbon dioxide gas evolved out from the solution. After the reaction was completed. The solution was back titrated with a NaOH solution (3.05mL, 0.1500M). Write the reaction equation for the reaction of MCO3 and HCl
If a 17.5 g sample of iron(III) oxide reacted with 5.00 L of carbon monoxide at 788 torr and 76 degrees celsius until one reactant is completely consumed, how many grams of iron are produced?
What will happen when a HCl (aq) solution is added to a Na2CO3 (aq) solution? Explain and give the molecular and net ionic equations for the reaction.
A bomb-type calorimeter is used to measure the heat evolved by the combustion of glucose, C6H12O6. Write the balanced reaction. A 3.00-g sample of glucose
Give the electron-domain and molecular geometries for the following molecules and ions (enter the appropriate number from thefollowing list).
The concepts of sensitivity and detection limit are often used interchangeably. Specify the difference between these two concepts.
A titration of 200.0 mL of 1.00 M H2A was done with 1.10 M NaOH. For the diprotic acid H2A, Ka1 = 2.5 × 10-5, Ka2 = 3.1 × 10-9. Calculate the pH after 600.0 mL of 1.10 M NaOH have been added.
The boiling point of a liquid increases as the pressure above the liquid increases. In contrast to boiling food in an open pot, pressure cookers trap the steam, which raises the internal pressure, which raises the boiling point of water, causing a..
Problem- What is the resulting pH if 500 mL of buffer solution (4.3M C6H5COOH ka=6.6x10^-5 and 3.3M C6H5COOK) are mixed with 50.0mL of 2.5M KOH
Ksp for MgCO3 at 25C is 2.0x10^-8. What are the molar concentrations in a saturated solution at this temperature
A compound contains 40.0% carbon, 6.7% hydrogen, and 53.3% oxygen (by mass). calculate empirical formula.
The chloride remained in solution because it was soluble. Next, an excess amount of silver nitrate was added, a reaction occurred, and silver chloride was precipitated which was removed from the solution by filtration.
