Answer:

D

Explanation: In order to separate liquids with similar boiling points,theoretical plates are the ones that must be maximized because two liquids would be at equilibrium with all properties being the same

What is the molarity if I take 10mL of 20 volumes Hydrogen Peroxide?
Kryger [21]

Answer:

1.635 M

Explanation:

Given:

10 mL of 20 volumes Hydrogen Peroxide

Here,

20 volumes of Hydrogen Peroxide means that on decomposition of 1 mL of H₂O₂ 20 mL of O₂ is obtained

also,

means 1 dm³ of H₂O₂ solution produces 20 dm³ oxygen

Now,

at 298K and 1 atm

20 dm³ oxygen = \frac{\textup{20}}{\textup{24.47}}  moles

or

= 0.817 moles

also,

2H₂O₂ → 2H₂O + O₂

thus,

1 dm³ of solution must contain 2 × moles of O₂ as moles of H₂O₂

thus,

Number of moles of H₂O₂ = 2 × 0.817

or

Number of moles of H₂O₂  = 1.635 moles

Hence,

For 20 volume hydrogen peroxide is 1.635 M

How is the amount of work done on an object relative to its change in energy?​
koban [17]

Kinetic energy is produced when the amount of work done on an object relative to its change in energy.

Explanation:

A strong connection is present between within work as well as energy. When work is performed on an object energy is added along with it . Energy can be defined as ability to do certain amount of work on the other hand work means to change in energy . Kinetic energy is produced when the object is in moving position and potential energy is produced when the object is at resting position.
