Submarines need to be extremely strong to withstand the extremely high pressure of water pushing down on them. An experimental research submarine with a volume of 15,000 liters has an internal pressure of 1.2 atm. If the pressure of the ocean breaks the submarine forming a bubble with a pressure of 250 atm pushing on it, how big will that bubble be?
The first equivalence point for the titration of 0.2567 grams of a weak acid is reached when a volume of 26.80mL of 0.0510 M NaOH(aq) has been added. What is the molar mass of the acid?
What will happen to the equilibrium as OH- ions are added?
If 16.87 grams of nitric acid are reacted with a large amount of aluminum metal, what volume of hydrogen gas would be produced at STP?
If the outermost electron in a potassium atom were excited to a 4d-orbital and then fell to the same orbitals, describe qualitatively how the emission spectrum would differ from that of hydrogen (do not do any calculations). Explain your answer.
A quantity of oxygen occupies a volme of 19.2L at STP. How moles of oxygen are present?
A compressed gas cylinder contains 1.00 x 103 g of argon gas. The pressure inside the cylinder is 2050 psi at a temperature of 18oC. How much gas remains in the cylinder if the pressure is decreased to 650psi at a temperature of 26oC?
The pressure of 9.0 L of an ideal gas in a flexible container is decreased to one-eighth of its original pressure, and its absolute temperature is decreased to one-forth of the original. What is the final volume of the gas?
the phosphorylation of 2 moles of ADP to ATP and has a deltaG= -135 kJ/mol. What is the deltaG for the conversion of glucose into lactic acid?
A gas expands and does P-V work on the surroundings equal to 327 J. At the same time, it absorbs 121 J of heat from the surroundings. Calculate the change in energy of the gas.
what is the osmolarity of a solution that has a concentration of NaCl of 0.300 mol/L?
the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3. How far into the sheet from this high-pressure side will the concentration be 1.8 kg/m3?
Ideally what should the ratio between the three slopes (AlCl3 slope= 483.0 , CaCl2 slope= 421.4, and NaCl slope= 181.9) be? What are your actual experimental ratios?
