What is the oxidation half-reaction for 2Mg + O2 + 2Mgo?

Chemistry
1 answer:
miv72 [106K]3 years ago
5 0

Answer:

B => Mg° => Mg⁺² + 2e⁻

Explanation:

2Mg° + O₂ => 2MgO  rewrite => Mg° + 1/2O₂ => 2MgO

Oxidation Half Rxn => Mg° => Mg⁺² + 2e⁻

Reduction Half Rxn => 1/2O₂ + 2e⁻ => 2O⁻

__________________________________-

FYI Note =>  For half-reactions one always finds the electrons listed on the product side of the reaction for oxidation reactions and for reduction reactions on the reactant side.

A gas sample occupies 4.2L at a pressure of 101 kPa. What volume will it occupy if the pressure is increased to 235 kPa
taurus [48]

1.8 L

<h3>Explanation</h3>

The volume of a gas, V, is inversely proportional to the pressure on it, P. That is:

V₁ · T₁ = V₂ · T₂.

Rearranging gives:

V₂ = V₁ · T₁ / T₂ = 4.2 × (101 / 235) = 1.8 L

The average bond energy (enthalpy) for a C=C double bond is 614 kJ/mol and that of a C−C single bond is 348 kJ/mol. Estimate the
AysviL [449]

Answer:

4.42x10⁻¹⁹ J/molecule

Explanation:

At a double bond, there's sigma and a pi bond, and at a single bond, there's only a sigma bond. Thus, if the energy to break both sigma and pi is 614 kJ/mol, and the energy to break only the sigma bond is 348 kJ/mol, the energy to break only the pi bond is:

E = 614 - 348 = 266 kJ/mol

Knowing that 1 kJ = 1000 J, E = 266,000 J/mol

By Avogadro's number, 1 mol = 6.02x10²³ molecules, thus:

E = 266,000 J/mol * 1mol/6.02x10²³ molecules

E = 4.42x10⁻¹⁹ J/molecule
