Explanation:
Reaction:
Cu + 2AgC₂H₃O₂ → Cu(C₂H₃O₂)₂ + 2Ag
The problem is to split the reaction into oxidation and reduction halves:
The oxidation half is the sub-reaction that undergoes oxidation
The reduction half is the one that undergoes reduction:
The ionic equation:
Cu + 2Ag⁺ + 2C₂H₃O₂⁻ → Cu²⁺ + 2C₂H₃O₂⁻ + 2Ag
Oxidation half:
Cu → Cu²⁺ + 2e⁻
Reduction half:
2Ag⁺ + 2e⁻ → 2Ag
C₂H₃O₂⁻ is neither oxidized nor reduced in the reaction.

Not quite sure what your question is asking. Chromium-52, the most common isotope. Among lesser common isotopes there could be Chromium-53, Chromium-56, etc. I would have to look specifically at what exists. The percent abundance in the universe multiplied by each of these mass numbers and added determines the atomic mass number a displayed on the periodic table.
Answer:
D. Asthenosphere
Explanation:
The theory of plate tectonics states that the lithosphere which is the solid outer crust of the earth contains segmented plates that shift to the asthenosphere. The asthenosphere is the upper part of the mantle that is molten in form.
So, the ability of the plates to move over to the asthenosphere, is an important feature of the plates. There are different points in the earth where the plates merge and separate.
Answer:
a. the pH is only determined by the concentration of B and no titrant is added to the solution yet
b. when acid is added to the weak base B it is converted to conjugal acid BH+
Explanation:
