How many mL of .125M AgNO3 and mL of .839M NaCl are needed to react and produce 1.000 gram of solid AgCl?
What is the maximum number of electrons in an atom that can have the following quantum numbers. Explain.
a liquid unknown was found to be soluble in cyclohexane and alcohol the unknown was found to have a boiling point of 58
A researcher plans to compare two treatment conditions by measuring one sample in treatment 1 and a second sample in treatment 2. The researcher will then compare the scores for the two treatments.
Calculate the pH of a solution that is 0.028 M dimethylamine and 0.057 M dimethylammonium chloride. The Kb of dimethylamine is 5.4x10-4
A gas was enclosed in a rigid-walled container. The initial temperature and pressure were 52°C and 0.55 atm, respectively. If the final pressure were 2.41 atm.
Use Henderson Hassalbalch equation to calculate how much HCl must be added to a liter of buffer that is 1.5 M in acetic acid and 0.75M in sodium acetate to result in a buffer pH of 4.10? Ka = 1.8 x 10-5
Calculate the oxygen content of the plasma in mM! 1 ml plasma dissolves 24 uL oxygen at 38 degrees C if the partial pressure is 103 kPa.
For 0.51 M HCN (Ka=6.2 x 10-10), mark the major species found in the solution. H+ , HCN , CN-, H2O , OH, Now calculate the pH of the 0.51 M HCN solution (Ka= 6.2 x 10-10).
A buffer is prepared by mixing 295 mL of 0.210 M HCl with 584 mL of 0.559 M ammonia (NH3). Given that the Kb of NH3 is 1.8 x 10-5, calculate the pH of the solution.
2.0 L of gas A at 1.0 atm and 1.0 L of gas b at 1.0 atm are combined in a 3 L flask. The flask is sealed and over time they react to completely to give gas C according to 2A(g) + B(g)= C(g)
