I need a proper discussion post on:

Biotic Interactions and Population Dynamics: How does energy move in food systems

Part A A fuel cell differs from a battery because the current is being generated from a reduction-oxidation (redox) reaction in which the reactant is consumed. A classic example of a fuel cell is the phosphoric acid fuel cell (PAFC), which have been used in stationary power generators, buses, and even submarines. Fuel cells require an electrolyte (similar to batteries) to carry electrically charged species between the electrodes, and a PAFC utilizes phosphoric acid (H3PO4) as its electrolyte. Phosphoric acid has three acidic protons that can dissociate in water, as highlighted in red here: H3PO4. However, it is considered a weak acid because some of the acid will remain in molecular form when dissolved in water. Write the complete ionic equation that depicts the dissociation of the first proton for the weak acid phosphoric acid (H3PO4). Make certain you include all charges for any ions produced. Express you answer as a chemical equation including phases. Titrations as analytical neutralization reactions Neutralization reactions can occur between any combination of weak/strong acids and bases. When we want to determine the concentration of a base in solution, we can apply the concept of neutralization by reacting the base with a known amount of an acid in the presence of an indicator (a compound that changes color depending on the pH). This method of determining the concentration of a base is called acid-base titration, and it can also be used to determine the concentration of an acid by titrating it with a known amount of base. A common acid to use for titrations is potassium hydrogen phthalate (written as KHP or KHPh; do not confuse the P for phosphorus). The reason KHP is common is because it is solid at room temperature, and we can accurately mass the amount that is added to solution. As a soluble salt, KHP completely dissociates to form a potassium ion (K+) and an acidic hydrogen phthalate ion (HP−), which is a weak acid that has only one acidic hydrogen. This ionization is depicted below. KHP(s) → K+(aq)+HP−(aq) Although ionization (the formation of ions) occurs as a result of acid dissociation for most weak acids, KHP ionizes before acid dissociation occurs. In other words, HP− is a weak acid ion. Part C If you wanted to determine how much KOH (potassium hydroxide; a strong base) was dissolved in water, you could titrate it with a known amount of KHP (potassium hydrogen phthalate; a weak acid) until a color change indicates that the base is completely neutralized. The molecular equation below depicts this neutralization reaction. KHP(aq)+KOH(aq)→K2P(aq)+H2O(l) Write the net ionic equation that depicts the neutralization of the base by potassium hydrogen phthalate. Instead of using the entire chemical formula of phthalate, use HP− to represent the acidic hydrogen phthalate ion and P2− to represent the phthalate ion. Express your answer as a net ionic equation including phases.

Your mini-essay should show understanding of at least 3 of the principles which define science as mentioned in the link above. You should clearly articulate which three you are focusing on in your post.

Focuses on the natural world

Aims to explain the natural world

Uses testable ideas

Relies on evidence

Involves the scientific community

Leads to ongoing research

Benefits from scientific behavior

The reader should understand why the evidence you found meets those 3 principles. The point of this paper is not to 'prove' the topic in one way or the other. The 'answer'' does not matter. What does matter is that the manner in which you prove the topic is done SCIENTIFICALLY!

You should use at least 2 sources of information (properly cited) to support your claim as well. You may use Wikipedia as background information for your benefit ONLY. You must find two additional independent sources of information to include in your discussion post. Please refer to the "citations" page under "course information" in the content link for specific instructions on how to cite a source. You will be graded on your demonstrated understanding of the topic, your comprehension of the information contained in your sources, and evaluation of the topic based on at least 3 of the scientific principles. Please comment on 2 posts as well.
