Question : Please provide completely balanced equations for the following chemical reactions. Please include the states of reatcants and products also. In addition, indicate the oxidizing agent in all of the applicable redox (oxidation-reduction) reactions:
1) Burning magnesium ribbon in oxygen.
2) Combustion of phosphorus.
3) Combustion of sulphur.
4) Dissolving copper in concentrated nitric acid.
5) Dissolving magnesium oxide in hydrochloric acid.
6) Dissolving calcium in water.
7) Dissolving co..
Answer : You expect too much to be done for you.
If you were to perhaps ask for any single one of these reactions to be balanced for you, you would get much better responses. But instead you seem to have simply copy-pasted you homework questions for others to do for you.
Show some work of your own and make an effort to learn.
To get you started,
1) 2Mg (s) + O2 (g) --> 2MgO (s)
In this reaction, Magnesium metal (s) is oxidized by Oxygen gas (g) to form Magnesium Oxide (s).
Question : redox reactions, oxidation, quantum numbers, thermochem, lewis dot structures, bond enthalpy, hybridization, chemistry of solids and liquids (vapor pressure and such), Energies of Solution Formation (solubility, pressure, temperature, and other factors), Chemical Kinetics (rate laws, reaction mechanics, and stuff), organic reactions, chemical equilibrium, Acid and Base properties and reactions, applications of Aqueous Equilibria (buffer solutions and such), Electrolytic Chem
Answer : They are connected through some basic theories: the theory of matter (atomic theory, and the fact that all chemical reactions are the result of exchange or sharing of electrons); electromagnetism (linking electricity and magnetism)nuclear theory (the structure of the nucleus, and the interaction between protons and neutrons), and thermodynamics (theories explaining exchange of kinetic energy).
The development of quantum mechanics and quantum electrodynamics have been developed in order to combine the elements of electromagnetism thermodynamics and nuclear theory into one single theory. This work is still underway.
Question : Like say if there is a redox reaction like this:
Br^- + BiO3^- -----> Br2 + Bi
Is BiO3^- automatically the oxidizing agent because it contains oxygen, and so Br^- is the reducing agent?
Answer : No, it's not generally true.
For example, O does not take part at all in the following redox reaction:
2I- + Cl2 -> I2 + 2Cl-
The only thing that counts is the change in the oxidation number.
