This will be a power point presentation for an introductory chemistry class. I will have to video myself presenting the powerpoint and send that in. Here are the instructions:
Imagine you are a forensic scientist assigned to analyze the scene of a restaurant that has recently been destroyed by a fire. The local news wants you to describe what happened to the public in a short video so the community can have some questions answered.
Prepare a 3- to 4-minute video to submit to the local news station. In your video, your goal is to educate the public about the chemistry involved in what happened and how chemistry will provide additional answers.
In the video, you must:
Describe what happened. Use your understanding of states of matter, energy, and chemical reactions to support your response.
Describe the additional chemical evidence or other scientific factors related to chemistry you will investigate. Use your understanding of acids and bases and states of matter to share the types of information you will gather.
Summarize how the public can enhance their safety and prevent fires. Use your understanding of chemical reactions and energy to support your recommendations.
Remember, your audience is the public, not scientists. As a scientific professional, you will need to use your expertise in scientific concepts to inform your audience while using language that is accessible and easy for everyone to understand.
In your response, include some of the vocabulary introduced in the course readings, such as:
Matter
Atoms
Molecules
Solid
Liquid
Gas
Mixture
Mass
Law of conservation of mass
Temperature
Heating
Energy
Kinetic energy
Potential energy
Chemical energy
Endothermic
Exothermic
Heating
Temperature
First law of thermodynamics
Second law of thermodynamics
Liquid
Solid
Density
Solvent
Solute
Solution
Concentration
Acid
Base
Equilibrium
Molecules
pH
Reaction
Reactants
Products
Molecules
If you could just make a powerpoint about this and make it to where I can present it that would be perfect. APA format. 2-3 references. I will upload photos of the grading rubric. Please let me know if you have questions.

This is a DISCUSSION, NOT AN ESSAY. Do not use extravagant words, as this is a simple discussion post. I will provide an example from one of my classmates. Here are the instructions: This week, we will take the chemistry concepts we have explored and apply them to real-world situations.
Respond to the following in a minimum of 175 words:
Reflect on the concepts we have learned so far: states of matter, energy, acids and bases, and chemical reactions.
Pick a story related to these topics from the news that has occurred in the past five weeks.
Summarize the story and discuss how at least one of the concepts from this course influenced the outcome.
Explain the concept you chose and how it relates to the story.
Discuss what the outcome of the story may have been if matter had behaved differently. Be sure to use the vocabulary related to the concept you picked in your response.
Here is an example of one of my classmates posts:
Recently, an immense discovery in the field of batteries was announced. Researchers created a new form of battery that is capable of holding substantially greater amounts of electricity and is healthier than current batteries made of lithium-ion. This novel cell uses a solid-state electrolyte rather than a liquid one, which offers various advantages.
The most relevant idea from our course to this scenario is states of matter. In this scenario, the term “state of matter” refers to the chemical composition of the battery’s electrolyte, which might be solid or liquid. In a normal lithium-ion battery, the solution known as electrolyte is liquid. This liquid permit lithium ions to pass between the batterie’s pair of electrodes, which is required for the battery to work. However, electrolytes that are liquid have some downsides. They can leak and cause the power source to malfunction or catch fire. They also limit how much charge the battery can store. The researchers in this tale created a battery using a solid-state electrolyte. This kind of solid electrolyte does not provide the same risk of leakage or combustion as a liquid electrolyte. It also enables the battery’s ability to store more electrical power because it can withstand greater voltages.
If matter had behaved differently, the outcome of this story could have been very different. For example, if solid electrolytes did not allow lithium ions to move between the electrodes, then this new type of battery would not work. The researchers would have had to find a different way to increase the energy density and safety of the battery, or they might not have been able to improve the battery at all.
In conclusion, the state of matter is a fundamental concept in chemistry that can have significant real-world implications, as demonstrated by this news story.
Another example:
In the past five weeks, a significant development in the energy field relates to the use of chemical reactions for sustainable energy production. A recent study by researchers at the University of Chicago (Duan, 2024) explored the role of electrocatalysis in increasing the efficiency of chemical reactions. The researchers found that applying electrical energy to a reaction can improve the yield of products without needing to rely on traditional heat-driven processes. This process is especially important for hydrogen production, a key component in clean energy technologies.
The concept of energy in chemical reactions, as discussed in this course, plays a critical role in understanding this development. In chemical reactions, energy is often needed to break bonds in reactants, and the reaction may release or absorb energy as products are formed. In the case of electrocatalysis, electrical energy replaces thermal energy, enhancing the efficiency of reactions. This application of electrical energy is more sustainable and can reduce environmental impacts by lowering energy consumption in industrial applications (Patel & Zhang, 2024).
If the reaction could not respond to electrical input, the process would not have been efficient, and the desired products might not have been produced in the quantities necessary for practical applications. This illustrates how the type of energy used in chemical reactions can significantly influence the outcome, and it highlights the importance of energy management in both chemical reactions and sustainability efforts.
