In basic solution, Te$^{2-}$ and SO$_3^{2-}$ ions react spontaneously. Consider the reaction below. 2Te$^{2-}$(aq) + 2SO$_3^{2-}$(aq) + 3H$_2$O(l) $\rightarrow$ 2Te(s) + 6OH$^{-}$(aq) + S$_2$O$_3^{2-}$(aq) $E_{cell}^o = 0.57$ V Part 1 of 2 Write the balanced half-reactions for this process. Include states of matter in your answers. Reduction half-reaction: Oxidation half-reaction: Part 2 of 2 If $E_{tellurium}^o$ is -1.14 V, calculate $E_{sulfite}^o$. Be sure your answer has the correct number of significant figures.

You work for a company that is launching a new line of gas grills and are in charge of specifying a bottle to hold the propane fuel used for the grill. The storage parameters that you have been given are: - Desired volume: 0.5 ftÂ³ - Desired capacity: 5 lb - Maximum design temperature: 150Â°F - Max allowed cost: $35/bottle A RFQ (request for quotes) has resulted in the following three quotes from compressed gas bottle suppliers: 1. ABC Corp. Model A-23 bottles with the following specifications: - 0.5 ftÂ³ volume rated for max pressure of 500 psi - Unit cost of $37.50/each - The company also offers new customers a first order choice of "premiums" valued at ~$250. 2. XYZ Company, Model R2311 bottles with the following specification: - 0.5 ftÂ³ capacity - Burst strength of 1800 psi - Unit cost: $45/each 3. The New Guys Co., Model X-45 0.5 ftÂ³ bottles at $31.95/each You consulted with the salesmen for XYZ and New Guys regarding their bids and received the below follow-ups: - XYZ: "Yes, the cost is high, but for the conditions you quoted, you need that high of a burst strength." - New Guys: "Uh well, I, uh, I can't find that pressure rating right now. I'm sure they are safe. We guarantee all of our products. We've had very few complaints." With the above information, do the following: a. Determine what the true pressure will be in the tanks at the conditions given. b. Write a short analysis of each company's bid, including pros and cons (factors for and against accepting their bid). In these analyses, address any safety or ethical concerns with the bid.
