Calculate the molarity of acetic acid in a viegar sample, knowing that 5.00 mL of vinegar requires 43.50 mL of 0.105 M NaOH to jut reach the phenolphthalein endpoint in a titration.
Acetic acid when pure, has a freezing point of 16.0 Celsius; Liquid acetic acid has a heat capacity of 1.96J/g*C. A 25.0 g piece of solid acetic acid at 16.0C is placed into an insulated container containing 50.0g of liquid acetic acid at 50.0C
The rate constant of a chemical reaction increased from 0.100s^-1 to 2.90s^-1 upon raising the temperature from 25.0 degree celcius to 43.0 degree celcius
Calculate the concentration of argon in lake water at 20C. if the partial pressure of argon is 0.0090 atm and Henry's constant is 0.0015
It takes 254kj/mol to eject electron for a certain metal surface. What is the longest wavelength of light that can be used to eject electrons from the surface of this metal via the photoelectric effect.
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.
when 1 mole of N2 is isothermally compressed from 1 atm to 1000 atm at 0C. Find the fugacity coefficient of N2 at 0C and 1000atm. HINT: Recall that for a pure material, the chemical potential is just the molar gibbs free energy.
