10 Given the balanced ionic equation representing a reaction:
Anon25 [30]

Answer:

Option (A) Each Zn atom loses 2 electrons, and each Co2+ ion gains 2

Explanation:

To know the right answer to the question, let us observe the changes in the oxidation number of Zn and Co. This is illustrated below:

Zn(s) + Co2+(aq) → Zn2+(aq) + Co(s)

The oxidation number of Zn changes from 0 to +2 indicating that Zn has lose 2 electrons.

The oxidation number of Co changes from +2 to 0 indicating that Co has gain 2 electrons.

Therefore, option A is the correct answer.

In step 2 of the experimental procedure, you added 6 M sodium hydroxide to the copper(II) nitrate solut form copper(II) hydroxid
kicyunya [14]

Answer:

The solution becomes colorless and a light blue precipitate is formed.

Explanation:

When sodium hydroxide is added to copper(II) nitrate solution, a precipitate of  copper(II) hydroxide is formed.

The solution gradually becomes colorless as the light blue precipitate appears.

The reaction is complete (enough sodium hydroxide has been added) when the blue color of the solution completely disappears.

The equation of the reaction is;

Cu(NO3)2(aq) + 2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq)

How is the scientific meaning of salt different from the common meaning of salt
kondaur [170]
The scientific meaning of salt is an ionic compound that is formed when an acid and a base reaction take place and is neutralized.
The common meaning of salt (table salt) is specifically the organic mineral of sodium chloride (NaCl) and is digestible.
Ionic salts are often not digestible (or not commonly digested, anyway)

Which equation best represents the behavior of acetic acid, hc2h3o2, in water?
frutty [35]

The equation that best represents the behavior of acetic acid in water is; CH3CO2H + H2O ⇄ CH3CO2− + H3O+.

Acetic acid, like all other acids dissociates in water. The equation for the dissociation of acetic acid in water is; CH3CO2H + H2O ⇄ CH3CO2− + H3O+.

During this dissociation, the acid proton in acetic acid is transferred to water to form the oxonium ion H3O+.

The presence of H3O+ in solution accounts for all the observed properties of acetic acid in solution.
