Answer : The correct option is, (D) ClO^-(aq)+H_2O(l)+2e^-\rightarrow Cl^-(aq)+2OH^-(aq)

Explanation :

Rules for the balanced chemical equation in basic solution are :

  1. First we have to write the unbalanced chemical reaction.
  2. Now balance the main atoms in the reaction.
  3. Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
  4. If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
  5. If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion (OH^-) at that side where the less number of hydrogen are present.
  6. Now balance the charge.

The balanced chemical equation in a basic solution will be,

ClO^-(aq)+H_2O(l)+2e^-\rightarrow Cl^-(aq)+2OH^-(aq)

Hence, the correct option is, (D)

You need to use the formula--> P1V1= P2V2 (Boyles's law)

P1= 14 bar
V1= 312 mL
P2= ?
V2= 652 mL

now we plug the values into the formula.

(14 x 312) = (P2x 652)

P2= (14 x 312)/ 652= <span>6.70 bar</span>

Crude petroleum is a mixture of many different components. How might one separate out the components to begin the process of ref
dimaraw [331]

Fractional distillation is used for the refining of crude petroleum.

<h3>How are the components of crude petroleum separated out?</h3>

Fractional distillation is the procedure used to separate crude oil's numerous constituents.

  • A mixture is divided into several components, known as fractions, using fractional distillation.
  • A combination of hydrocarbons makes up crude oil. The crude oil evaporates, and in the fractionating column, its vapors condense at various temperatures.
  • The hydrocarbon molecules in each percent have a comparable number of carbon atoms and a comparable range of boiling points.
  • The mixture is placed above a tall fractionating column that has multiple condensers coming off at various heights.
  • The bottom of the column is warm, while the top is cool. High boiling point compounds condense at the bottom, whereas low boiling point substances condense as they ascend.

Please help me and explanation would be really awesome thank you!
valentina_108 [34]

Answer:

So the answer would be 10 moles

Explanation:

1) Start with the molecular formula for water: H_{2} O!

2) If there are 10 moles of water use a mole ratio to calculate the moles of oxygen it would produce.

(This question is... interesting... since they chose an element that is diatomic in free state so It could TECHNICALLY be two answers, moles of O or moles of O_{2})

The mole ratio is 1 moles of H_{2}O to 1 moles of O. This is because the coefficient for oxygen in water is simple 1, so the ratio is 1:1.

3) that means if 10 moles of water decompose, they decompose into 10 moles of H_{2} and 10 moles of O.

Extra:

About what I was saying before about the question being slightly interesting:

10 moles of pure oxygen is produced but free state oxygen exists as O_{2} so it could possibly be 10 OR 5! However, notice it says elements. This leads me to believe the answer is 10 (monatomic oxygen) instead of 5 (free state/diatomic oxygen).

I hope this helps!
