Many elements can have more than one charge or oxidation number. In this set of problems, we will assign oxidation numbers to each atom in sulfate, carbonate, bicarbonate, bisulfate, sulfite, nitrate, nitrite, chlorate, and perchlorate.
Each of the above examples assumes an oxidation number of +1 for hydrogen and -2 for oxygen. There are exceptions to this. We will also look at hydride and peroxide.
Determine the characteristic wavelengths if an electron are accelerated through an electric potential to a kinetic energy of 18kev.
Photosynthesis is estimated to produce 330.0 g (dry weight) of plant matter per square meter, 50% of which is carbon. Calculate the total number of grams of carbon "fixed" each year by 1000 square meters.
What is the difference between a strong acid and a weak acid. Calculate [H30+] in each aqueous solution at 25 C and classify each solution as acidic or basic one.
Compute A current is drawn from the cell until 1.20 grams of Ag have been deposited at the Ag electrode. Determine the value of E for the cell at that stage of operation.
Determine osmolarity of solution when 25.0 grams of aluminum chloride dissolves in 2.50 liters of H2O.
Compute the solubility of silver sulfite, Ag 2 SO 3 in units of grams per liter and complete and balance these given redox equations by the half reactions method (the oxidation reaction and the reduction reaction)
it is observed that a volume of 29.15 mL of KOH was neede to complete the process of titration. Determine what is the concentration of this unknown HCl solution?
At 25 degree celcius ,the second order reaction NOCL(g) - NO (g) + 1/2 CL2 (g) is 50 % complete after 5.82 hours when the initial concentration of Nitrosyl chloride is 4.46 ml/L.what time will it take for the reaction to be 75 % complete.
When a sample of 5.00-g rams of Potassium thiocyanate is dissolved in H2O in a calorimeter that has a total heat capacity =6.225 kJ•K-1, the temperature decreases by 0.200 Kelvin. compute the molar heat of solution of Potassium thiocyanate.
Determine At what temperature will Kp 2.00? if it is given that Delta H = +57.2 kJ/mol,Kp = 0.113 at the temperature of 298 Kelvin?
Given that Iron(III) oxide or ferric oxide (molar mass = 159.7 g/mol) reacts with Carbon monoxide (molar mass = 28.0 g/mol).
The excess of acid needed 16ml of 0.25M Naoh for neutralization. then Calculate the percentage of calcium carbonate and magnesium carbonate?
