A detailed explanation, one paragraph of the colligative property being discussed and why that property changes the way that it

does when the amount of solute is increased.
A detailed description, at least one paragraph, of a real-world application of the colligative property, including an explanation of how this application of the colligative property is important or useful to those affected. The real-world example must be one that was not mentioned in the lesson.

2. Why is the lonic compound Nacl (table salt) able to dissolve in a glass of the molecular compound water (H20)? (3 points)
melomori [17]

Answer:

The correct answer is C ions from the solute molecules have a strong attraction to the polar solvent molecules.

Explanation:

NaCl or Sodium chloride is an ionic compound which easily get dissolved in polar molecular compound such as water(H2O).

      Both NaCl and H2O are polar compound because the atoms that forms NaCl and H2O have vast difference in their electronegativities.As a result the bonding electrons in both NaCl and H2O are not equally shared.

     NaCl get dissolved in water molecules by dipole dipole interaction.

Identify the species oxidized, the species reduced, the oxidizing agent and the reducing agent in the following electron transfe
Vesna [10]

Answer:

In the given chemical reaction:

Species Oxidized: I⁻

Species Reduced: Fe³⁺

Oxidizing agent: Fe³⁺

Reducing agent: I⁻

As the reaction proceeds, electrons are transferred from I⁻ to Fe³⁺

Explanation:

Redox reaction is a chemical reaction involving the simultaneous movement of electrons thereby causing oxidation of one species and reduction of the other species.

The chemical species that <u><em>gets reduced by gaining electrons </em></u><u>is called an </u><u><em>oxidizing agent</em></u>. Whereas, the chemical species that <u><em>gets oxidized by losing electrons </em></u><u>is called a </u><u><em>reducing agent</em></u><u>.</u>

Given redox reaction: 2Fe³⁺ + 2I⁻ → 2Fe²⁺ + I₂

<u>Oxidation half-reaction</u>: 2 I⁻ +  → I₂ + 2 e⁻                 ....(1)

<u>Reduction half-reaction</u>: [ Fe³⁺ + 1 e⁻ → Fe²⁺ ] × 2

                                   ⇒  2 Fe³⁺ + 2 e⁻ → 2 Fe²⁺       ....(2)

In the given redox reaction, <u>Fe³⁺ (oxidation state +3) accepts electrons and gets reduced to Fe²⁺ (oxidation state +2) and I⁻ (oxidation state -1) loses electrons and gets oxidized to I₂ (oxidation state 0).</u>

<u>Therefore, Fe³⁺ is the oxidizing agent and I⁻ is the reducing agent and the electrons are transferred from I⁻ to Fe³⁺.</u>

Describe how the meniscus is used to read volume measurements on a graduated cylinder
katrin2010 [14]

Answer:Tthe liquid in a graduated cylinder curves up at the edge where the liquid meets the wall of the cylinder. This curve in the liquid is called the meniscus and is used to determiine the volume of liquid in a graduated cylinder by observing the measurement tick closest to the bottom of the meniscus.

What do the following results from the TEST FOR LIFE tab indicate about the sample?
Tcecarenko [31]

The result for TEST FOR LIFE is that the sample produces ATP. The sample is plant.
D Is going to be your answer

Explanation:
The chloroplasts are cell structures that are photosynthesis. The Golgi apparatus is the site transport of substance out of the cell. Mitochondria is the site of cellular respiration.
The two main functions of organelle is that it stores the herediatary material, DNA and it coordinates the cell's activities like growth, intermediary metabolism, protein synthesis, and reproduction. Eukaryotes are the cells of advanced organisms have a nucleus.
The results of the sample produces ATP, the sample is plant and the plant cells have an envelope surrounding the nucleus.

Hope this helps.!!! And please mark brainliest thank you!!
