Answer: 1. Ethylene is a stable molecule with two carbon atoms connected by a double bond. Polyethylene is made by the reaction of multiple ethylene molecules in the presence of a catalyst.

2. The term “plastics” includes materials composed of various elements such as carbon, hydrogen, oxygen, nitrogen, chlorine, and sulfur.

3. Polyethylene (PE) is made by the reaction of multiple ethylene molecules in the presence of catalysts to break the double bond and connect the carbon atoms into a chain . The longer the chain, the higher the molecular weight. Polymers can have molecular weights in the millions.

Improper or incomplete usage of citations can lead to plagiarism.

Without proper usage of citations, teachers or whoever is looking over your work, may think because you do not hold acceptable citations, that they will think it is plagiarized. Plagiarism is taking another person's work or ideas without citing it. Citation or direct quotation could save you from plagiarism.

2C3H7OH + 9O2 -&gt; 6CO2 + 8H2O
MAVERICK [17]

Answer:

Up to 18\; \rm mol \rm CO_2.

Explanation:

The equation for this reaction: 2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O is indeed balanced.

Notice that the coefficient of \rm C_3 H_7 OH is 2 while that of \rm CO_2 is 6.

Therefore, each unit of this reaction would consume 2 units of \rm C_3H_7OH while producing 6 units of \rm CO_2. In other words, this reaction would produce three times as much \rm CO_2\! as it consumes \rm C_3H_7OH\!.

If all that 6\; \rm mol of \rm C_3H_7OH molecules are actually consumed through this reaction, three times as many \rm CO_2 molecules would be produced. That corresponds to 3 \times 6\; \rm mol = 18\; \rm mol of \rm CO_2\! molecules.
