A 25.0-mL aliquot of vinegar was diluted to 250 mL on a volumetric flask. Titration of 50.0-mL aliquots of the diluted solution required an average of 34.88 mL of 0.09600 M NaOH. Express the acidity of the vinegar in terms of the percentage (w/v) ..
A container (8.65-L ) holds two gases mixture at 31 °C. The partial pressures of gas X and gas Y, respectively, are 0.206 atm and 0.867 atm. If 0.200 mol a third gas is added with no change in temperature or volume determine the total pressure be..
Calculate the expectation value for the potential energy of the H atom with the electron in the 1s orbital. Compare your result with the total energy
What is the solubility of MnS, in grams per liter, in a buffer solution that is 0.115M HC2H3O2 - 0.505 M NaC2H3O2? For MnS, Kspa=3x10^7.
Select all of the correct statements about the relative acid strengths of pairs of acids from the choices below. HCl is a stronger acid than H2S because Cl is more electronegative than S.
Determine At what temperature will Kp 2.00? if it is given that Delta H = +57.2 kJ/mol,Kp = 0.113 at the temperature of 298 Kelvin?
What is the heat change in J associated with 74 g of gaseous butane at 91 oC changing to solid at -170 oC? c(butane) (gas) = 2.31 J/ (g.K) c(butane) (liq) = 1.65 J/(g.K) c(butane) (s) = 1.32 J/ (g.K) ?Hfus(butane) = 6.885 kJ/mol
If a solution has a pH of 2.36 and you do a 20-fold dilution of it with ultrapure reagent-grade water, what will its pH be after you dilute it
A 41 kg person drinks 280. g of milk, which has a "caloric" value of approximately 3.0 kJ/g. If only 18% of the energy in milk is converted to mechanical work,
Use bond energy values to estimate the reaction enthalpy for the formation of ammonia from nitrogen gas and hydrogen gas. Note that N2 contains a triple bond. You will need structural formula.
hydrogen gas is collected over water at 21 degrees C and an atmospheric pressure of 748 mm Hg. what is the partial pressure of hydrogen gas in the mixture
A mixture of gases contains 2.42 g of Kr, 4.58 g of Ar, and 5.74 g of NO2. What is the partial pressure in atm of each component of this mixture if it is held in a 11.5-L vessel at 31.3 oC? Use R = 0.0821 L-atm/mol-K as the value of the gas consta..
