The compound p4s3 is oxidized by nitrate ions in acid solution to give phosphoric acid, sulfate ions, and nitric oxide no. what

natulia [17]

Answer is: the coefficient of phosphoric acid is 12.
Chemical reaction: P₄S₃ + NO₃⁻ + H⁺ → H₃PO₄ + SO₄⁻ + NO.
Reduction half reaction: NO₃⁻ + 4H⁺ + 3e⁻ → NO + 2H₂O /·38
Oxidation half reaction: P₄S₃ + 28H₂O → 4H₃PO₄ + 3SO₄²⁻ + 44H⁺ + 38e⁻ /·3.
38NO₃⁻ + 152H⁺ + 3P₄S₃ + 84H₂O → 38NO + 76H₂O + 12H₃PO₄ + 9SO₄²⁻ + 132H⁺.
Balnced chemical reaction:
3P₄S₃ + 38NO₃⁻ + 20H⁺ + 8H₂O → 12H₃PO₄ + 9SO₄²⁻ + 38NO.

When comparing voltaic cells to electrolytic cells, oxidation occurs at the.

stira [4]

When comparing voltaic and electrolytic cells oxidation occurs at both the anode and the cathode.

<h3>What is an electrolytic cell?</h3>

In an electrolytic cell, the reaction is non-spontaneous so it requires some input of energy for it to function while for a voltaic cell, the reaction is spontaneous.

Oxidation occurs at the anode and reduction occurs at the cathode.

Thus, when comparing voltaic and electrolytic cells oxidation occurs at both the anode and the cathode.

An "extensive property" is a material property that depends on the amount of material present in a sample. An "intensive propert

TEA [102]

Answer: Rate of reaction is an "extensive property". Rate of generation of a chemical species is an "intensive property"

Explanation:

Let´s check out the Factors that affect the speed of reactions:

Temperature, Physical state of the reagents, Presence of a catalyst, Pressure, light, Concentration of the reagents.

When having a general chemical reaction like this:

aA + bB → cC + dD

Usually the rate of reaction is represented by the next equation

$Rate = k [A]^{x} [B]^{y}$

Where k= constant

x, y = reactant orders

A, B = reactant concentration

As we can see in the last equation, the rate of reaction depends directly of the amount of material present in a sample, that is why it is an "extensive property"

The rate of generation of a chemical species, depends of other factors like Temperature, Presence of a catalyst, Pressure. As we can see all the factors that allow the speed of generation of a new chemical species let us know that this is an intensive property because it doesn´t depends of the amount of material.
