Calculate the volume of carbon dioxide at 20.0 C and .960 atm produced from the complete combustion of 3.50 kg of methane. Compare your result with the volume of CO2 produced from the complete combustion of 3.50 kg of propane (C3H8)
Volume of Co2 from 3.60 kg methane?
A voltaic cell consists of a Hg/Hg2^2+ electrode(E degrees=0.85V) and a Sn/Sn^2+ electrode(E degrees=-0.14V). Calculate[Sn^2+]if [Hg2^2+]=0.36 M and Ecell=1.04V at 25 degrees C.
1.00 mole of pure NOCl and .907 mole of pure Cl2 are placed in a 1.00-L container. Calculate the equilibrium concentration of Cl2(g).
a 25.0 ml sample of H3PO4 requires 50.0ml of 1.50ml M NaOH for complete neutralization. what is the molarity of the acid?
A 0.4780-g sample of impure Ca(OH)2 is dissolved in enough water to make 57.00 mL of solution. 20.00 mL of the resulting solution is then titrated with 0.1140-M HCl.
What is the value of Kf for acetic acid, given that its freezing temperature is 16.6 C and its density is 1.049 g/mL? Experiments show that a solution prepared by dissolving 5.00 grams of water
Tf will be negative and so you must use negative Kf values. Either way, the freezing point of the solution should be lower than that of the pure solvent. Assuming 100% dissociation, Find the freezing and boiling points of 1.85 m Na2SO4(aq).
Indicate whether or not, each has a fixed shape or fixed volume. In addition, include their relative kinetic energies. Pictures can be drawn to assist in the explanation.
why must one half reaction in the table of standard reduction potentials be arbitrarily assigned a value of 0 volts? why were not all of the half cell potentials
What mass of Ag2CO3(s) in grams is theoretically produced by mixing 125 mL of 0.315 M Na2CO3(aq) and 75.0 mL of 0.155 M AgNO3(aq)?.
The pH at 25 °C of an aqueous solution of the sodium salt of p-cresol (NaC7H7O) is 11.60. Calculate the concentration of C7H7O- in this solution, in moles per liter. Ka for HC7H7O is equal to 6.7E-11.
Determine the % relative error for the following quantities: if there is no uncertainty given for a specific value, assume an absolute error of "1" in the last digit.
If a 100.0 g sample of water at 60.0 degreesC is added to a 100.0 g sample of water at 10.0 degrees C, determine the final temperature of the water.
