Write a balanced half-reaction for the reduction of bismuth oxide ion to bismuth ion in basic aqueous solution. Be sure to add physical state symbols where appropriate.

Answers

Answer 1

Answer:

[tex]3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-[/tex]

Explanation:

Hello there!

In this case, according to the required half-reaction, we start by setting it up from bismuth (V) oxide ion to bismuth (III) ion:

[tex]BiO_3^-\rightarrow Bi^{3+}[/tex]

Thus, next realize that the oxidation state of Bi in BiO3^- is 5+ because oxygen is 2- (-2*3+x=-1;x=-1+6;x=+5), so we obtain:

[tex](Bi^{5+}O_3)^-\rightarrow Bi^{3+}[/tex]

Thereafter, we realize three water molecules are needed on the right in order to balance the oxygens and consequently 6 hydrogen atoms on the left to balance hydrogen:

[tex]6H^++(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O[/tex]

Now, since the balance is is basic media, we add six molecules of hydroxide ions in order to produce water with the hydrogen ones:

[tex]6OH^-+6H^++(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O+6OH^-\\\\6H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O+6OH^-\\\\6H_2O-3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-[/tex]

Then, we accommodate the waters to obtain:

[tex]3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-[/tex]

Best regards!

When an organism eats a plants,the energy and nutrients stored in the consumed organism flows up to the____level​

Answers

Answer:

Energy is transferred between trophic levels when one organism eats another and gets the energy-rich molecules from its prey's body.

Explanation:

The flow of energy in an ecosystem is always linear ie uni direction. At each energy step in food chain, the energy received by the organisms is used for its own metabolism and maintenance. The left over energy is passed to next higher trophic level. Thus the energy flow decreases with successive trophic level.

Litmus paper indicator shows following color  changes for lemon it is, blue litmus to red, for ash and blood  it is red litmus to blue  indicating their acidic nature in case of lemon and alkaline nature in case of ash and blood.

What is an indicator?

Indicator is defined as a chemical substance which is chemically a weak acid or a weak base which changes it's color depending upon the concentration of hydrogen ions present in the solution.They dissociate slightly in water to produce ions.

These are generally derived from plant pigments and are of slightly acidic or basic in nature.There are three types of indicators:

1) natural indicators

2) synthetic indicators

3) olfactory indicators.

These are mainly used in determination of end point of titrations. Every indicator has it's pH range in which it can perform effectively.These are usually organic compounds.

How
many mols are in 151 g of dinitrogen monoxide? ​

Answers

Answer:

3.43 moles

Explanation:

To convert moles into grams you must take the number of grams and divide it by the atomic mass of the compound.

in this case, grams is 151 and N2O has an atomic mass of 44.013

so your equation would look like

151/44.013=3.430804535

your answer would be 3.43 moles

Why is NH3 not considered a base under the Arrhenius definition of acids and bases?

SELECT AN ANSWER

a. It does not react with acids.
b. NH3(aq) does not contain OH- ions.
c. NH3 is considered a base under the Arrhenius definition, but not under the Bronsted-Lowry definition.
d. It does not cause a color change when mixed with an acid-base (pH) indicator.

Answers

Answer:

b. NH3(aq) does not contain OH- ions.

Explanation:

According to Arrhenius in his definition, a base is a substance that has the ability to increase the hydroxyll ion (OH-) of an aqueous solution. In other words, Arrhenius bases dissociates into OH- when dissolved in water.

According to this question, ammonia (NH3) will not be considered an Arrhenius base because it does not contain OH-. This means that ammonia (NH3) cannot dissociate into hydroxyll ion when dissolved in water.
