Calculate the value ??of [OH-] from the given values in each solution and then label the solution as acidic or basic:
(a) [H3O+]= 1.5X10-2 M
(b) [H3O+]= 2.5X10-12 M
How many moles of Cl- are in 1.000 mL of the aqueous 2.500 molar HCl solution mentioned above. How many moles of H+ are in 1.000 mL of the aqueous 2.500 molar HCl solution mentioned above
What is the pressure of the gas in this mercury manometer if h = 69 mm and atmospheric pressure is 749 mmHg
Calculate the standard net potential for the reaction observed if a nickel strip were placed in a chromium(II) solution?
1.2 mole of a monoatomic ideal gas that occupies a volume of 13L at 248K spontaneously and isothermically expands until its voulme is doubled.
Identifying dipolar ions, There is a question in my textbook that reads P-amino acid is not a dipolar ion, whereas glycine (aminoacetic acid) is not a dipolar ion- how do you account for this?
An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295k and volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1 mL atm K^-1 mol..
Assume that you have carried out a radical chlorination reaction on (R)-2- chloropentane and have isolated (in low yield) 2,4-dichloropentane.
If you plot the volume of a sealed gas sample versus its temperature in degrees C, at what T in degrees C will V=0 if you extrapolate the data
(a) Calculate the work that must be done at 298.15 K and 1.00 bar against the atmosphere for the production of CO2 (g) and H2O (g) in the combustion of 8.50 mol C6H6 (l). Calculate the standard enthalpy of the reaction. (b) Calculate the change in..
Describe the direction of ion and electron flow in a anode/cathode diagram (galvanic cell diagram)
why was Mendeleev's decision to leave blank spaces on his table sometimes was referred to as his most significant contribution to the periodic table?
You titrate 1.740 g of a solid unknown acid that was dissolved in 100.0 mL of distilled water; the initial pH value was 2.5. You found that pH= pKa=4.2 when 12.50 mL of NaOH was added. The concentration of the sodium hydroxide was 0.500M. Calculat..
