Use the Nernst Equation to calculate Ecell at 25 C for electrolysis of aqueous sodium chloride if the concentration of chlorine in the brine solution is 4.5 M and the partial pressure of Cl2 is 0.001 atmospheres.
Chlorine will spontaneously react with iodide to produce chloride and iodine. What is E^o for this reaction.
Research the number of electrons that can fit into energy levels higher than the third level. Why does that explain why there is a space in the lower periods of the periodic table?
Determine what is the mass percent yield from 2.57 grams of Sb in excess Sulphur , if 1.56 g of Sb 2 S 3 is obtained?
At 340 K, Kp = 69 for the reaction H2(g) + I2(g) ->2HI(g). 50.0 g of HI is injected into an evacuated 5.00-L rigid cylinder at 340 K. What is the total pressure inside the cylinder when the system comes to equilibrium?
or the reaction H2(g)+CO2(g) H2O(g)+CO2(g) at 700C, Kc=.534. Calculate the number of moles of H2 that are present at equilibrium
The equilibrium constant, Kc, for the following reaction is 1.29E-2 at 600 K: COCl2(g) CO(g) + Cl2(g)
From data below, calculate the total heat (in J) associated with the conversion of 0.412 mol ethanol gas (C2H6O) at 501°C and 1 atm to liquid ethanol at 25.0°C and 1 atm
If the gas is at 23C and 1.0 atm, what mass of helium is in the blimp? The Goodyear blimps, which frequently fly over sporting events, hold approximately 1.85×105 ft^3 of helium.
How many atoms are contained in one unit cell of of this element? The atomic mass of the element is 193.5 amu.
Consider a 53.5 g sample of H2O(g) at 117°C. What phase or phases are present when 134 kJ of energy is removed from this sample.
Titration of sodium carbonate with HCl to the methyl orange end point involves the reaction of 1 mole of Na2CO3 with 2 moles of HCl. Write the balanced chemical equation in a.
Using pH-based arguments only, why do scientists use phosphate-based bufers instead of buffers made using acetic acid
If the methane contained in 4.00 L of a saturated solution at 25 C was extracted and placed under STP conditions, what volume would it occupy?
