3. Identify the oxidizing agent in each of the fol- lowing reactions. a) Cu2 + (aq) + Mg (s) + Cu (s) + Mg2 + (aq) b) Fe, O3 (s) + 3CO (g) → 2Fe (1) + 3CO, (g)

The standard reduction potentials of lithium metal and chlorine gas are as follows: Reaction Reduction potential (V) Li + (aq) + e-→Li (s) - 3.04 Cl2 (g) + 2e-→2Cl - (aq) + 1.

An increase in the temperature of reactant causes an increase in the rate of reaction. Which of the following is the best explanation?

The energy released in the fission of a 235u nucleus is about 200 mev. how much rest mass (in kg) is converted to energy in this fission?

The ostwald process is used commercially to produce nitric acid, which is, in turn, used in many modern chemical processes. in the first step of the ostwald process, ammonia is reacted with oxygen gas to produce nitric oxide and water.
