The physical separation techniques used are :

  • Decanting
  • Filtration
  • sublimation
  • distillation

<h3>What are physical separation techniques ?</h3>

Physical Separation techniques are procedures applied for the separation of a mixture of two different states pf matter based on their physical properties. usually solid and liquid mixtures. When a mixture of liquid and solid is separated by carefully pouring out the liquid while leaving the solid behind that separation technique is known as decanting.

Decanting, filtration, sublimation and distillation are the separation techniques.

<h3>Identify the physical separation technique?</h3>

Decanting is a process in which a liquid is carefully poured out, leaving the solid behind in the container.

A solid is caught on paper or a membrane while the liquid passes through, this process is called Filtration.

Sublimation is a process in which a solid mixture is heated in which one component transitions directly between solid and gas.

A solvent is added to dissolve only one mixture component and then the liquids are separated, this process is known as distillation.

Provide the name(s) for the tertiary alcohol(s) with the chemical formula C6H14O that have a 4-carbon chain. Although stereochem
pochemuha

Answer:

Explanation:

A tertiary alcohol is a compound (an alcohol) in which the carbon atom that has the hydroxyl group (-OH) is also bonded (saturated) to three different carbon atoms.

Based on the question, the only <u>tertiary alcohol that can result from C₆H₁₄O that have a 4-carbon chain</u> is

2-hydroxy-2,3-dimethylbutane

     H  OH   H    H

      |     |       |      |

H - C - C -   C  - C - H

      |     |       |      |

     H  CH₃  CH₃ H

From the above, we can see that the carbon atom having the hydroxyl group is also bonded to three other carbon atoms. And since we aren't considering stereochemistry, this is the only tertiary alcohol we can have with a 4-carbon chain

Which has more particles, a mole of copper (Cu) atoms or a mole of neon
goldfiish [28.3K]

Answer:

D

Explanation:

it is neon because neon has a higher atomic number so it would have more protons and neutrons and electrons in one atom thus having more particles in one mole

A 0. 462 g sample of a monoprotic acid is dissolved in water and titrated with 0. 180 m koh. what is the molar mass of the acid
Len [333]

The molar mass of the acid if 28. 5 ml of the koh solution is required to neutralize the sample is 90.23g/mol.

<h3>For the calculation of molarity of solution</h3>

Molarity = (moles of solute/volume of solution) × 1000

Given,

Molarity of KOH solution = 0.180 M

Volume of solution = 28.5 mL

0.180 = (moles of KOH/ 28.5) × 1000

Moles = (0.18× 28.5)/1000

= 0.00513 mol

<h3>Chemical equation for the reaction</h3>

HA + KOH ------- KA + H2O

1 moles of KOH reacts with 1 moles of HA.

So, 0.00513 moles of KOH react with 0.00513 moles of HA.

<h3>To calculate the molar mass for given number of moles</h3>

Number of moles= given mass/ Molar mass

Given,

Mass of HA = 0.462 g

Moles of HA = 0.00512 mol

0.00512 = 0.462/ Molar mass

Molar mass = 90.23 g/ mol.

Thus the molar mass of HA required to neutralize the 28.5 mL of KOH is 90.23g/mol.
