List and describe, in your laboratory journal, the four forces acting on amino acids placed in water. These four forces ultimate
Vlad1618 [11]

The following are the four forces acting on the amino acids placed in water:  

1. Van der Waals forces: The natural stickiness of every single atom, resulting due to the movement of its electron cloud.  

2. Electrostatic charge: The ions of a side chain, which have either minus or plus charge.  

3. S-S bonds: Many sulfur-containing amino acids like cysteine situated in the distinct parts of the protein chain, associated with each other, forming a covalent bond, which connects together the two distinct parts of a protein molecule.  

4. Hydrogen bonds: As the oxygen of the water molecule is strong, it pulls the electron cloud away from its two hydrogens, making its hydrogen somewhat positive and thus possessing the tendency to associate with the negative poles on the adjacent molecules.  

Hydrophobic is defined as the tendency to repel or fail to mix with water. While hydrophilic is defined as possessing the tendency to mix with or dissolve in water.  

Hydrophilic amino acids are water-loving, while hydrophobic amino acids are water-hating. Hydrophilic amino acids will react in a manner, which is contrasting from their response to water. When positioned in oil, they will be more fascinated with each other in comparison to the surrounding molecules. The non-polar hydrophobic amino acids will not be herded in combination by the oil, as they were by water, so they will get dissolve efficiently.

Reptile [31]

Answer:

The Coriolis effect is an apparent deflection in the paths of moving objects caused by Earth's faster speed near the equator than near the poles. In the solar system, the greatest expression of this effect occurs in planetary atmospheres. On Earth, for example, the air around us moves freely above the ground.

In the laboratory, a student combines 28.3 mL of a 0.489 M manganese(II) acetate solution with 12.5 mL of a 0.339 M manganese(II
Eddi Din [679]

Answer:

M = 0.441 M

Explanation:

In this case, we have two solutions that involves the Manganese II cation;

We have Mn(CH₃COOH)₂ and MnSO₄

In both cases, the moles of Mn are the same in reaction as we can see here:

Mn(CH₃COO)₂ <-------> Mn²⁺ + 2CH₃COO⁻

MnSO₄ <------> Mn²⁺ + SO₄²⁻

Therefore, all we have to do is calculate the moles of Mn in both solutions, do the sum and then, calculate the concentration with the new volume:

moles of MnAce = 0.489 * 0.0283 = 0.0138 moles

moles MnSulf = 0.339 * 0.0125 = 0.0042 moles

the total moles are:

moles of Mn²⁺ = 0.0138 + 0.0042 = 0.018 moles

Finally the concentration: 12.5 + 28.3 = 40.8 mL or 0.0408 L

M = 0.018 / 0.0408

M = 0.441 M

This would be the final concentration of the manganese after the mixing of the two solutions
