<u>Answer:</u> The balanced chemical equation is written below.

<u>Explanation:</u>

Galvanization is defined as the process in which a protective layer of zinc is applied to iron or steel to prevent the metal from rusting.

Zinc prevents the oxidation of iron and acts as a reducing agent in the process.

The half reaction for the process follows:

<u>Oxidation half reaction:</u>  Zn\rightarrow Zn^{2+}+2e^-

<u>Reduction half reaction:</u>  Fe^{2+}+2e^-\rightarrow Fe

Net chemical equation:  Zn+Fe^{2+}\rightarrow Zn^{2+}+Fe

Hence, the balanced chemical equation is written above.

Classify each of the following reactants and products as an acid or base according to the Bronsted theory: H3PO4 + C6H5O- &lt;=&
Alexxandr [17]

Answer:

H₃PO₄ is an acid because donates the proton to fenolate.

Fenolate is the base because accepts the proton from the acid.

Explanation:

Bronsted theory mentioned that acid is the one that donates a proton to another compound and base is the one that receives it.

H₃PO₄   +   C₆H₅O⁻    ⇄      H₂PO₄⁻      +       C₆H₅OH

acid              base              conj. base            conj. acid

H₃PO₄ is an acid because donates the proton to fenolate.

Fenolate is the base because accepts the proton from the acid.

If we follow the dissociation, the diacid phosphate can donate two more protons, it is still a Bronsted acid, but it can act as an acid or a base. This is called amphoteric.

the copper anode is weighed before and after the electrolysis reation. if the copper anode is not completely dry when it is weig
Dmitrij [34]

Answer:

Faraday's constant will be smaller than it is supposed to be.

Explanation:

If the copper anode was not completely dry when its mass was measured, mass of the copper must be heavier than it should have been. Hence, the calculated Faraday’s constant would be smaller than it is supposed to be since when calculating Faraday’s Constant, the charge transferred is divided by the moles of electrons.
