To calculate the solubility product, Ksp, of the compound Ag2CrO4. We need its dissociation reaction and the concentration of each ion in the solution. Since the concentration is not given then we can only show an expression for the calculation of such.
Ag2CrO4<span> > 2Ag+ + CrO4-2
</span>
Ksp = [Ag+]² [<span>CrO4 2-] </span>
Well, that depends on cost, maintenance, and power output most of the time. Geothermal seems to be best because you could heat up water, and the heat from said water can be used to create electricity. Making it extremely eco-friendly, which makes it the best in that regard.
The balanced equation for the reaction is as follows;
2Fe + 3S ---> Fe₂S₃
molar ratio of Fe to Fe₂S₃ is 2:1
mass of Fe₂S₃ to be produced is - 96 g
therefore number of moles of Fe₂S₃ to be produced is - 96 g / 208 g/mol
number of Fe₂S₃ moles = 0.46 mol
according to the molar ratio
when 2 mol of Fe reacts with 3 mol of sulfur then 1 mol of Fe₂S₃ is produced
that for 1 mol of Fe₂S₃ to be produced - 2 mol of Fe should react
therefore for 0.46 mol of Fe₂S₃ to be produced - 2 x 0.46 = 0.92 mol of Fe is required
mass of Fe required - 0.92 mol x 56 g/mol = 51.5 g
mass of Fe required is - 51.5 g
The correct answer is option 4. One benefit of nuclear fission reactions is the production of energy. Fission reaction is one type of nuclear reaction. This type occurs when a nuclei is being divided. <span>Fission reaction takes place in any of the heavy nuclei after
capture of a neutron. </span>
The average kinetic energy of an ideal gas is calculated as
KE_avg = 3/2 kT
where T is the temperature in Kelvin and k=R/N_A; R is the universal gas constant and N_A is the number of moles.
Thus, upon substitution we get
KE_avg = 3/2(8.314/1)(100+273)
KE_avg = 3/2(8.314)(373)
KE_avg = 4651.683
The average kinetic energy of 1 mole of a gas at 100 degree Celsius is 4651.683 J.
