Write an equation that represents the action in water of nitrous acid as an arrhenius acid.

Chemistry

Arrhenius Acid:
                       Arrhenius Acid is any specie which when dissolved in water produces H⁺ (proton) Ions.

Nitrous Acid:
                    Nitrous Acid also acts as Arrhenius Acid when dissolved in water.

                          HNO₂  +  H₂O    →    NO₂⁻  +  H₃O⁺
Where,
                                H₃O⁺    ⇆    H⁺  +  H₂O

As HNO₂ produces H⁺ Ions in water, so it is an Arrhenius Acid.

What happens when an atom has more electrons than can fit in one energy
Rina8888 [55]

Answer:

If any atom has more electrons than one energy level can hold, then automatically the electron is accommodated in the next energy level (shell). The remaining extra electrons starts to fill the next energy level. This produces the valency of that particular atom.

1. What is the name for rise of deeper water to the surface?
Vikentia [17]

Upwelling

Explanation:

The rise of deeper water to the surface is called upwelling.

Upwelling is a term used in oceanography to describe the rise of cold and denser water to the surface.

  • This occurs usually along the short where wave action is very prevalent.
  • Surface wave pushes away warm water.
  • Then deeper nutrient-rich cold water rises due to low density and volume of water on top.
  • This nutrient rich water supports biological activities because they are rich.
  • Wind along the coast can also force surface water down.

How many of the following are oxidation-reduction reactions? I. reaction of a metal with a nonmetal II. synthesis III. combustio
nadezda [96]

Answer : The oxidation-reduction reactions are:

I. reaction of a metal with a nonmetal

II. synthesis

III. combustion

Explanation :

Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.

Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.

Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.

I. Reaction of a metal with a nonmetal :

When sodium react with chlorine gas then it react to give sodium chloride.

2Na+Cl_2\rightarrow 2NaCl

In this reaction, the oxidation state of sodium changes from (0) to (+1) and shows oxidation and the oxidation state of chlorine changes from (0) to (-1) and shows reduction. So, It is an oxidation-reduction reaction.

II. Synthesis reaction :

A chemical reaction where multiple substances or reactants combine to form a single product.

When hydrogen react with oxygen then it react to give water.

2H_2+O_2\rightarrow 2H_2O

In this reaction, the oxidation state of hydrogen changes from (0) to (+1) and shows oxidation and the oxidation state of oxygen changes from (0) to (-2) and shows reduction. So, It is an oxidation-reduction reaction.

III. Combustion reaction :

A chemical reaction in which a hydrocarbon reaction with the oxygen to give product as carbon dioxide and water.

When methane react with oxygen gas then it react to give carbon dioxide and water.

CH_4+2O_2\rightarrow CO_2+2H_2O

In this reaction, the carbon of methane gain oxygen and shows oxidation and the oxygen gas gain hydrogen and shows reduction. So, It is an oxidation-reduction reaction.

IV. Precipitation reaction :

It is defined as the reaction in which an insoluble salt formed when two aqueous solutions are combined.

The insoluble salt that settle down in the solution is known an precipitate.

It is a double displacement reaction. So, it is not an oxidation-reduction reaction.

V. Decomposition reaction :

A chemical reaction in which the the larger molecule decomposes to give two or more smaller molecules.

The oxidation state remains same on reactant and product side. So, it is not an oxidation-reduction reaction.

Compare the molar concentration of the crystal violet solution to that of the sodium hydroxide solution. approximately how much
romanna [79]
The <span>molar concentration of the crystal violet solution is more concentrated than that of the sodium hydroxide solution. It is because the crystal violet solution has more solute in it compared to the sodium hydroxide.</span>
