Sort these reactions into the proper categories. $Br_2(g) + BaI_2(s) \rightarrow BaBr_2(s) + I_2(g)$ $2Al_2O_3(s) \rightarrow 4Al(s) + 3O_2(g)$ $BaCl_2(aq) + K_2CO_3(aq) \rightarrow BaCO_3(s) + 2KCl(aq)$ $2Zn(s) + O_2(g) \rightarrow 2ZnO(s)$ $2C_2H_2(g) + 5O_2(g) \rightarrow 4CO_2(g) + 2H_2O(g)$ combination decomposition single replacement double replacement combustion

Question 4 2.5 pts Fern, Inc., Ivy, Inc., and Jeremy formed a general partnership. Fern owns a 50% interest and Ivy and Jeremy each own 25% interests. Fern, Inc. files its tax return on an October 31 year-end; Ivy, Inc., files with a May 31 year-end, and Jeremy is a calendar year taxpayer. Which of the following statements is true regarding the taxable year the partnership can choose? The partnership must choose the calendar year because it has no principal partners. The partnership must choose an October year-end because Fern, Inc., is a principal partner. The partnership can request permission from the IRS to use a January 31 fiscal year under § 444. The partnership must use the "least aggregate deferral" method to determine its "required" taxable year. None of the above.

A potential drawback of SSDs is that the underlying flash memory can wear out. For example, one major manufacturer guarantees 1 petabyte ($10^{15}$ bytes) of random writes for their SSDs before they wear out. Given this assumption, estimate the lifetime (in years) of the SSD in Figure 1 for the following workloads: a. Worst case for sequential writes: The SSD is written to continuously at a rate of 170 MB/s (the average sequential write throughput of the device). b. Worst case for random writes: The SSD is written to continuously at a rate of 14 MB/s (the average random write throughput of the device). c. Average case: The SSD is written to at a rate of 20 GB/day (the average daily write rate assumed by some computer manufacturers in their mobile computer workload simulations). Reads Writes Sequential read throughput 250 MB/s Sequential write throughput 170 MB/s Random read throughput 140 MB/s Random write throughput 14 MB/s Random read access time 30 $\mu$s Random write access time 300 $\mu$s
