What is the net ionic equation of the reaction of \rm ZnCl_2 with \rm NaOH?
Calculate the concentration of oxygen in water given that the Henry's law constant of oxygen is 4.259 ×104 atm and the partial pressure of oxygen is 0.2 MPa.
acid is dissolved in water to produce a 1.51 M solution. The pH of the resulting solution is 2.52. Calculate the Ka for the acid.
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.
the excess I3- was titrated with 50.00 ml of a 0.02000 M Na2S2O3 solution. What was the mass percent of arsenic trichloride in the original sample?
As a result, the pressure inside the vessel drops to 30.64 atm at 25 C. Calculate the final percent by mass of ozone in the vessel.
What is the total pressure in a 25.0 L flask 20.0°C, which contains 0.127 moles of H2 and 0.288 moles of N2?
How many moles of H3O+ must be added to 482 mL of a solution to adjust the pH from 8.80 to 5.56? Use E notation and 3 significant figures.
The atmospheric sulfur dioxide concentration over a certain region is 0.12 ppm by volume. Calculate the pH of the rainwater due to this pollutant. Assume the dissolution of SO2 does not affect its pressure.
