6. PTFE, polytetrafluoroethylene (C2H4), is a widely-used plastic for things such as non-stick cookware, carburetor parts and instrument liners. It is chemically inert, but burns to give carbon dioxide and a number of other chemicals as follows: C2F2(s) + 4 O2(g) ---> 2 CO2(g) + 2 OF20) a. How many grams of CO2 will be produced when 1891 grams of PTFE is burned? b. A study shows the combustion is incomplete and when the 1891 grams of PTFE is burned, only 1487 grams of carbon dioxide is produced. What is the percent yield of the combustion? c. In a study of this reaction in the lab, 1500. grams of PTFE were burned with 1500. grams of oxygen gas in a closed container. How many grams of OF2 can be made? Which chemical is the limiting reactant? Show your work to verify your prediction.

Question
### PTFE Combustion and Chemical Reactions

**Question 6:** PTFE, polytetrafluoroethylene (C₂F₄), is a widely-used plastic for things such as non-stick cookware, carburetor parts, and instrument liners. It is chemically inert but burns to give carbon dioxide and a number of other chemicals as follows:

\[ \text{C}_2\text{F}_2 (s) + 4 \text{O}_2 (g) \rightarrow 2 \text{CO}_2 (g) + 2 \text{OF}_2 (l) \]

**Tasks:**

**a.** Calculate the amount of CO₂ produced when 1891 grams of PTFE is burned.

   - **Answer Box:** [ ]

**b.** A study shows the combustion is incomplete, and when 1891 grams of PTFE is burned, only 1487 grams of carbon dioxide is produced. Calculate the percent yield of the combustion.

   - **Answer Box:** [ ]

**c.** In a laboratory study of this reaction, 1500 grams of PTFE were burned with 1500 grams of oxygen gas in a closed container. Determine how many grams of OF₂ can be made and identify the limiting reactant.

   - **Answer Box for OF₂ Grams:** [ ]
   
   - **Answer Box for Limiting Reactant:** [ ]

- **Note:** Show your work to verify your predictions.
