Why would the cell potential be higher with the addition of 6 M Na2S solution to .001 M of CuSO4 (compared to 6 M NH addition to .001 M CuSO4)
How many grams of ammonium nitrite must be decomposed if 98.5 liters of nitrogen are to be produced?
A 4.80 g nugget of pure gold absorbed 288 J of heat. What was the final temperature of the gold if the initial temperature was 26.0°C.
A sample of argon gas collected at a pressure of 761 mm Hg and a temperature of 283 K has a mass of 32.2 grams. The volume of the sample is. answer in L please.
Joseph Priestley discovered oxygen in the eighteenth century by using heat to decompose mercury(II) oxide: 2 HgO(s) + heat --> 2 Hg(s) + O2(g)
How much time is required to produce 200g of alumimun metal for molten aluminum oxide dissolved in cryolite, if you use a 12.0 amp current.
Because electron transport is coupled to ADP phosphorylation, it is theoretically possible to drive electrons backwards up the chain, against the potential gradient, at the expense of ATP.
Suppose that ammonia (a monoprotic base), applied to a field as a fertilizer, is washed into a farm pond containing 3.0 × 106 L of water. If the pH of this pond is found to be 9.81.
A sample of ideal gas at room temperature occupies a volume of 34.0L at a pressure of 722 torr. If the pressure changes to 3610 torr, with no change in the temperature or moles of gas, what is the new volume, V2
a mixture of 0.140 moles of C is reacted with 0.117 moles O2 in a sealed, 10.0 L vessel at 500 K, producing a mixture of CO and CO2. the total pressure is 0.640 atm. What is the partial pressure of CO
What mass of this substance must evaporate in order to freeze 160 g of water initially at 21 0C? (The heat of fusion of water is 334 {J/g}; the specific heat of water is 4.18 {J/g c.K}.)
To learn how to calculate the solubility from Ksp and vice versa. Consider the following equilibrium between a solid salt and its dissolved form (ions) in a saturated solution:
where e is the magnitude of the charge on an electron and ε0 is the vacuum permittivity (a fundamental constant). What is the operator for this potential energy?
