Balanced chemical equation is 3CH₃CH₂OH + 2Cr₂O₇²⁻ + 16H⁺ → 3CH₃COOH + 4Cr³⁺ + 11H₂O.
<h3>What is Balanced Chemical Equation ?</h3>The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
The chemical equation
CH₃CH₂OH + Cr₂O₇²⁻ → CH₃COOH + Cr³⁺
First assign the oxidation number for each atom in the equation.
Oxidation: C₂H₆O → C₂H₄O₂ + 4e⁻
Reduction: Cr₂O₇ + 6e⁻ → 2Cr⁺³
Now, balance the charge
Oxidation: C₂H₆O → C₂H₄O₂ + 4e⁻ + 4H⁺
Reduction: Cr₂O₇ + 6e⁻ + 14H⁺ → 2Cr⁺³
Now balance the oxygen atoms
Oxidation: C₂H₆O + H₂O → C₂H₄O₂ + 4e⁻ + 4H⁺
Reduction: Cr₂O₇ + 6e⁻ + 14H⁺ → 2Cr⁺³ + 7H₂O
Now, make electron gain equivalent to lost
Oxidation: C₂H₆O + H₂O → C₂H₄O₂ + 4e⁻ + 4H⁺ } × 3
Reduction: Cr₂O₇ + 6e⁻ + 14H⁺ → 2Cr⁺³ + 7H₂O } × 2
Now,
Oxidation: 3C₂H₆O + 3H₂O → 3C₂H₄O₂ + 12e⁻ + 12H⁺
Reduction: 2Cr₂O₇ + 12e⁻ + 28H⁺ → 4Cr⁺³ + 14H₂O
Now, add the both equations
3CH₃CH₂OH + 2Cr₂O₇²⁻ + 16H⁺ → 3CH₃COOH + 4Cr³⁺ + 11H₂O
Thus from the above conclusion we can say that the balanced chemical equation is 3CH₃CH₂OH + 2Cr₂O₇²⁻ + 16H⁺ → 3CH₃COOH + 4Cr³⁺ + 11H₂O.

The pH of the buffer is 6.1236.
Explanation:
The strength of any acid solution can be obtained by determining their pH. Even the buffer solution strength of the weak acid can be determined using pH. As the dissociation constant is given, we can determine the pKa value as the negative log of dissociation constant value.
The pH of the buffer can be known as
The concentration of
Similarly, the concentration of [HA] =
Then the pH of the buffer will be
pH = 6.247 + log [ 0.304/0.404]
So, the pH of the buffer is 6.1236.
Answer:
a. 63.2%
b. 11.7%
c. 73.3%
d. 0.995%
e. 55.5%
Explanation:
An ionic compound is a compound that is formed by ions, so one of the elements must donate electrons (which is the cation, the positive ion), and the other will receive these electrons (which is the anion, the negative ion).
The power of an element has to attract the electrons is called electronegativity, and so, as higher is the difference of electronegative of the elements, it is more probable that one of them will "still" the electrons and will form an ionic compound. The percent of this ionic character can be found by the Pauling's equation:
*100%
Where is the electronegativity difference of the elements. Thus, consulting an electronegativity table:
a. = 1.5
= 3.5
*100%
%IC = 63.2%
b. = 1.6
= 2.1
*100%
%IC = 11.7%
c. = 0.7
= 3.0
*100%
%IC = 73.3%
d. = 1.7
= 1.9
*100%
%IC = 0.995 %
e. = 1.2
= 3.0
*100%
%IC = 55.5%
