The amount of manganese in steel is determined by changing it to permanganate ion. The steel is first dissolved in nitric acid, producing Mn(2+) ions. these ions are then oxidized to the deeply colored MnO4(-) ions by periodate ion (IO4(-)) in acid solution.
a. complete/balance equation...describe each reaction. calculate E and delta G at 25 degrees C for each reaction.
Stellar nuclear fusion begins with 1H and ends with 56Fe. Younger stars fuse hydrogen to form 4He, while older, more massive stars fuse helium to form heavier elements.
What is the molarity of the carbonate ion in sodium carbonate, Na2CO3, prepared by dissolving 3.5 g of sodium carbonate in enough water to form 0.800 L of solution?
The total volume of hydrogen needed to fill the Hindenberg was 2.0x10^8 L at 1.00 atm and 25 C. How many kilojoules of energy were evolved when it burned?
A student creates a coffee cup calorimeter for lab. The coffee cup contains 30 mL of water at a temperature of 55.5 °F. He then adds 65.4mL of water, at 165.5 °F, into the coffee cup. The final temperature of the coffee cup is 120.3 °F.
Why is the theoretical maximum final temperature reached by the water in a calorimeter always slightly higher than the highest recorded temperature
A 1.17 g sample of an alkane hydrocarbon gas occupies a volume of 674 mL at 28°C and 741 mmHg. Alkanes are known to have the general formula CnH2n+2.

What is the difference between the fresh meat with added sodium nitrite and the meat with added sodium nitrite plus sodium erythorbate?
How much energy is released per Kg of Dilithium formed? Mass of one atom of 6 Li is 6.015121 amu. Do not know where to start.
A chemical reaction at equilibrium is heated, briefly, by holding it over a flame. The equilibrium is seen to shift toward the products. What can be said about the enthalpy and entropy of the reaction
Will water or cyclohexene be present in greater amount in the distillate from co-distillation. Explain.
