Concept explainers
(a)
Interpretation:
A molecule of octane has to be compared with one of a fat or oil and two differences has to be listed.
Concept introduction:
Fats are triglycerides made up of one glycerol molecule and three fatty acid molecules. They are also considered as the hydrophobic substances which are soluble in the organic solvents and insoluble in water.
Saturated fats are the one which contain saturated fatty acids in it and it cannot be hydrogenated.
Unsaturated fats are the one which contain unsaturated fatty acids in it and it can be hydrogenated further.
(b)
Interpretation:
A biodiesel molecule has to be compared with a fat or oil.
Concept introduction:
Fats are triglycerides made up of one glycerol molecule and three fatty acid molecules. They are also considered as the hydrophobic substances which are soluble in the organic solvents and insoluble in water.
Saturated fats are the one which contain saturated fatty acids in it and it cannot be hydrogenated.
Unsaturated fats are the one which contain unsaturated fatty acids in it and it can be hydrogenated further.
Biodiesel:
It can be otherwise said to be FAME(Fatty acid methyl ester) and is derived from the transesterification of triglycerides from biomass.

Chemistry In Context
- Petroleum is a very valuable raw material for the synthesis of polymers. What if Congress decided that petroleum must be conserved as a raw material and could not be used as fuel? What could our society do for alternate sources of energy?arrow_forwardUse the web to research the amount of PVC polymer produced annually in the United States. What are the three most common uses of this polymer?arrow_forwardGive information about the polymer wafer invented by Robert Langer and Henry Brem to treat brain cancer. When the studies started, how did the idea come out, who found it, which university the studies were carried out, what exactly does the product work, when was the patent obtained? Write important information about this polymer wafer (Please don't give short answer)arrow_forward

- SUBJECT : GENERAL CHEMISTRY TOPIC : THERMAL RUNAWAY 1. Evaluate the effectiveness of current safety measures used in the production and disposal of electronic devices with lithium-ion batteries. Suggest alternative measures or improvements that could reduce the risk of thermal runaway. 2. Propose a research question related to thermal runaway in electronic devices. Describe how to conduct this investigation or study this research question. 3. Imagine a scenario where a thermal runaway event occurred in a crowded public space. Evaluate the potential hazards and risks, and propose strategies to mitigate them.arrow_forwardSUBJECT : GENERAL CHEMISTRY TOPIC : THERMAL RUNAWAY 1. Describe the role of chemistry in addressing the issue of thermal runaway in electronic devices, and propose potential avenues for research and development in this area. 2. What is thermal runaway, and how does it occur in electronic devices such as cellphones, power banks, and laptops?arrow_forwardWrite the Lewis structures and give the electron-region geometry, molecular geometry, and bond angles, and the hybridization of the central atom of these polyatomic ions and molecules.

- 5. The goal is to convince an investor to invest in your company so that you can build a factory to make ester compounds. For example, you could make hexyl pentanoate, and sell it for use in perfumes and make the investor money. You must come up with a compound that you can make and sell. You can use your textbooks and the internet as resources. At the end of your research, you must have the compound table filled out.arrow_forwardAnswer the following: NO PLAGIARISM 1. What are nanomaterials and how are they made? 2. What are the factors that need to be considered beforemanufacturing materials through nanotechnology? 3. What are the contributions of nanotechnology for theimprovement and sustainability of our environment?arrow_forwardThe chart shows average CO2 emissions for fossil fuel vehicles (gasoline, diesel, and hybrid gas‑electric), as well as electric vehicles. The ordinate is mg CO2 per mile driven per pound mass of the vehicle (called curb weight). For electric vehicles, CO2 emission varies in U.S. states because of the mix of fuels used to generate electricity. If electricity came entirely from solar power, there would be little CO2 associated with its production. California has the lowest CO2 emission for producing electricity and Ohio has the highest because it depends heavily on coal‑fired power plants. The chart does not include CO2 emission from manufacturing vehicles. When normalized for distance driven by each kind of vehicle before it is scrapped, CO2 emission associated with manufacturing electric vehicles is estimated to be 25–75% greater than CO2 emission associated with manufacturing gasoline and diesel vehicles. If manufacturing were included, CO2 emission associated with electric vehicles…arrow_forward
