A synchronous satellite, which always remains above the same point on a planet's equator, is put in orbit around Jupiter to study that planet's famous red spot. Jupiter rotates once every 9.84 h. Use the following data to find the altitude of the satellite above the surface of the planet. Jupiter has a mass of 1.90 1027 kg, and a mean radius of 6.99 107 m.
____________ km
Explain what is the pH of a buffer solution that is 0.34 M in Na2HPO4 and 0.46 M in KH2PO4? Ka1 = 7.1E-3, Ka2 = 6.3E-8, and Ka3 = 4.5E-13.
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
If 24.60 mL of a standard 0.3871 M NaOH solution is required to neutralize 43.87 mL of H2SO4, what is the molarity of the acid solution?
suppose the pressure inside a pressure cooker reaches 1.3 atm. By using the vapor-pressure table, estimate the temperature at which water will boil in this cooker
Problem- Tell whether the intensity of the red color of the solution would increase or decrease for each of these changes: (a) addition of more Fe3+ ion, (b) addition of more SCN- ion
In a certain experiment, 20.00 ml of 0.800M HCL were added to a O.1022 gram sample of MCO3. The excess HCL required 5.64 ml of 0.1000M NaOH for neutralization. Compute the molar mass of the carbonate and identify M.
Problem- For each pair below, write a balanced equation showing what happens when the two compounds are combined. If there is no reaction, show the solvated ions that result in the solution.
The subsequent four numbers are estimates of the mass of an object- 4.30 g, 5.82 g, 5.79 g, and 5.47 g. Explain what is the standard deviation to two significant figures
