Explanation:

Soaps attach to both water and grease molecules.

The grease molecules are attracted more strongly towards each other as compared to water molecules. Also, water molecules are smaller in size hence, strong intermolecular force is required to break the hydrogen bonds of water molecule so that grease or oil molecules can enter the water molecule.

A soap molecule goes in between water and grease molecule and helps them to bind. The force for linkage between water and grease molecule through the soap molecule is weak london dispersion force.

The soap molecule has its salt end as ionic and water soluble. When grease or oil is added to the soap and water solution then the soap acts as an emulsifier. The soap forms miscelles of the non-polar tails and grease molecules are trapped between these miscelles. This miscelle is easily soluble in water hence, the grease is washed away.

Thus, it can be concluded that the nonpolar end of a soap molecule attaches itself to grease.

Answer: The non-polar end of a soap molecule attaches itself to grease.

Explanation:

Soap molecule that is <em>miscelle </em>has two parts:

  • Polar part or hydrophilic part : This part interacts with polar water molecules.
  • Non-polar or hydrophobic : This part interacts with the non-polar molecules that is grease.

By the interaction of non-polar part with grease and interaction of  polar part with water due to which grease get easily dissolved in water.

Hence,the correct answer is : 'The non-polar end of a soap molecule attaches itself to grease'.

Glucose and amino acids are reabsorbed from the glomerular filtrate by the __________.
AleksandrR [38]

Answer:

Amino acids, along with glucose, are reabsorbed in the glomerular system with a passive or active mechanism as the fluid travels through the entire renal tubular system and enters the circulation again.

Active mechanisms are those that require expenditure of energy, that is, expenditure of the energy currency, while the passive ones do not, they occur through spontaneous non-energy processes such as osmosis, the osmotic gradient and the difference in concentrations in different compartments.

Explanation:

Glomerular filtration is the regulator of the excretion of metabolites and toxic molecules or not necessary for our body. That is why if the amino acid values ​​are high as well as those of glucose in urine, we will be facing a pathology.

If glucose is increased, it is because there is a glycemic peak in blood volume, hence possible diabetes.

And if the amino acids are increased, we could be facing an autoimmune or proteolytic pathology where a large amount of body proteins such as muscle proteins would be breaking down and releasing the amino acids that make it up, this phenomenon usually appears in those people who suffer from rhabdomyolysis in expenses very intense energy sources not appropriate.

On the other hand, glomerular filtration occurs in the kidney and is carried out by the nephron, which is the functional unit of the kidney, within it there is a specific tubular system in collection, absorption and reabsorption, added to the presence of Bowman's capsule.

The lab question is “Based on a substance’s properties, how can you determine whether its bonds are ionic or covalent?” Fill in
AleksandrR [38]
If the substance has high melting/boiling point, if it requires high temperature to dissociate into simpler particles, if it's structure is hard and if it conducts heat and electricity quite frequently, then it would be "Ionic compound" otherwise, it will be covalent compound. (compound with covalent bonds).

Substance with ionic bonds, would include... (mentioned in first sentence)

Hope this helps!

Multiply them together 28 cm * 22 cm * 0.30 cm= 184.8 cm^3 Since we have 2 identical sheets, double the total volume 184.8 cm^3 * 2 = 369.6 cm^3 Now multiple the volume by the density 369.6 cm^3 * 1.2 g/cm^3 = 443.52 g Round the results to 2 significant digits since all of the given figures are only 2 significant digits long. 443.52 g = 440 g</span>

1) ideal gas law: p·V = n·R·T.
p - pressure of gas.
V -volume of gas.
n - amount of substance.
R - universal gas constant.
T - temperature of gas.
n₁ = 0,04 mol, V₁ = 0,06 l.
n₂ = 0,07 mol, V₂ = 0,06 · 0,07 ÷ 0,04 = 0,105 l.
2) V₁ = 0,06 l, T₁ = 240,00 K.
T₂ = 340,00 K, V₂ = 340 · 0,06 ÷ 240 = 0,05 l.
