Answer:

Liquid water is held together by hydrogen bonds. Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water s hydrogen bonds.Water will not do this so the oil is forced to stay separate from the water.

Oil are the lipid molecule do not Mix With Water Because of Polarity. Oil and water don’t mix as it  is made up of non-polar molecules while water molecules are polar.

Lipids are organic biomolecule made up of carbon, hydrogen and oxygen with some other elements like phosphorus and nitrogen may be present.

A fatty acid which is an organic acid having hydrogen and general formula R-COOH where R represents hydrogen or a group of carbon and hydrogen atoms, for example stearic, palmitic and oleic acids.

Glycerol is another component which is a thick sweetish liquid, soluble in water and  can react with a fatty acid. where one molecule of glycerol combines with three molecule is fatty acids by formation of a bond called ester, here ester is also known as triglyceride.

The characteristics of the Bohr model allow you to find that the correct answer for the distribution of particles in the atom is:

   b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

The bohr model was initially developed for hydrogen, where it manages to fully explain the spectrum of the hydrogen atom, it was quickly spread to other multi-electronic atoms with the characteristic of having a single electron in their last orbit.

The extension to atoms with more than one electron in the last shell the model results are not completely correct.

The Bohr model uses Rutherford's knowledge that the atomic nucleus is a very small part of an atom that contains all its mass, that is, it contains the protons and neutrons and the electrons are in circular orbits around the nucleus.

In the case presented of Neon, its electronic configuration is

    1s² 2s² 2p⁶

Let's examine the different claims:

a) False. Protons and neutrons form the mass of the atom, therefore they are both in the nucleus.

b) True. The protons are in the nucleus and the electrons are in circular orbits.

c) False. All protons and neutrons must be in the nucleus, plus neon only has 10 neutrons.

c) False. The number of protons determines the type of atom. An atom with twenty protons is Calcium atom .

In conclusion, using the characteristics of the Bohr model we can find that the correct answer for the distribution of particles in the atom is:

  b) Ten protons would be located in the nucleus, and 10 electrons would be on the outside of the atom orbiting in rings.

Answer:

The required mass to prepare 2.5 L of 1.0 M NaOH solution is 100 g

Explanation:

We do this by preparing the equation:

Mass = concentration (mol/L) x volume (L) x Molar mass

Mass = 1.0 M x 2.5 L x 40 g/mol

Mass = 100 g

Answer:

[tex]100\; \rm g[/tex] of [tex]{\rm NaOH}\; (s)[/tex] would be required.

Explanation:

The quantity of solute in a solution of concentration [tex]c[/tex] and volume [tex]V[/tex] would be [tex]n = c \cdot V[/tex].

It is given that volume [tex]V = 2.5\; \rm L[/tex] for the solution in this question. It is also given that the concentration of the [tex]\rm NaOH[/tex] solute in this solution is [tex]c = 1.0\; \rm M[/tex], which is the equivalent to [tex]c = 1.0\; \rm mol \cdot L^{-1}[/tex].  

Apply the equation [tex]n = c \cdot V[/tex] to find the quantity of [tex]\rm NaOH[/tex] in this solution:

[tex]\begin{aligned}n &= c \cdot V \\ &= 1.0\; \rm mol \cdot L^{-1} \times 2.5\; \rm L \\ &= 2.5\; \rm mol\end{aligned}[/tex].

Multiply the quantity [tex]n[/tex] of [tex]\rm NaOH[/tex] in this solution with the formula mass [tex]M[/tex] of [tex]{\rm NaOH}\![/tex] to find the corresponding mass:

[tex]\begin{aligned}m &= n \cdot M \\ &= 2.5\; \rm mol \times 40\; \rm g \cdot mol^{-1} \\ &= 100\; \rm g\end{aligned}[/tex].

Thus, this solution would contain [tex]100\; \rm g[/tex] of [tex]{\rm NaOH}[/tex].

It would thus take [tex]100\; \rm g[/tex] of [tex]{\rm NaOH}[/tex] to prepare this solution.

Answer:

chemical stability is important to consider in the comprehensive assessment of pharmaceutical properties, activity, and selectivity during drug discovery.

Answer:

In general, molecules are stable because all their constituent atoms have sufficient "valence" electrons-that is, electrons that participate in chemical bonding. Such electrons reside in the outer, or valence, "shell," which must fill up with the appropriate number of electrons for the bound atoms to be come stable.

Measles is a communicable disease that requires immunization to prevent illness when exposed to it.

Measles is a communicable disease and highly contagious. It  is usually very serious in children. The disease can be contacted through droplets in the air, physical contact and through mother-to-child transmission.

It is a very serious disease as it is caused by a virus which replicates very fast in the throat and nose thereby creating symptoms such as runny nose, coughing, sneezing and is usually accompanied with a rash.

The severity and death rates is what gave rise to the creating of a measles vaccine which is usually given to babies after birth to make them immune to the potential exposure to the virus.

Diabetes, bronchitis and strep throat have no vaccine as they can always be treated or managed with over-the-counter drugs.
