10.48 When butane reacts with Br2 in the presence of Cl2, both bro- minated and chlorinated products are obtained. Under such conditions the usual selectivity of bromination is not observed. In other words, the ratio of 2-bromobutane to 1-bromobutane is very similar to the ratio of 2-chlorobutane to 1-chlorobutane. Can you offer an explanation as to 1 why we do not observe the normal selectivity expected for bromination? ra st 10.48 When butane reacts with Br2 in the presence of...

Part A In aqueous solution, hypobromite ion, Bro", reacts to produce bromate ion, Bro, and bromide ion, Br, according to the following chemical equation . 3 BrO" (aq) + Broj "(aq) + 2 Br" (aq) A plot of 1/(B0"] vs. time is linear and the slope is equal to 0.056 mst. If the initial concentration of BrO is 0.90 M, how long will it take one-half of the Brion to react? 12 s 8.05 0 20.5 5.0 x 1025 Submit...
Problem 3: Sampling a Cosine (again) The continuous-time signal ra(t) = cos (150) is sampled with sampling period T, to obtain a discrete-time signal x[n] = XanT). 1. Compute and sketch the magnitude of the continuous-time Fourier transform of ra(t) and the discrete-time Fourier Transform of x[n] for T, = 1 ms and T, = 2 ms. 2. What is the maximum sampling period Ts max such that no aliasing occurs in the sampling process?

(Software Testing) Homework #, BRO Generate a BRO‐adequate test set TBRO for pr: (a<0) ∨ (b=1) ∧ (c>2) ∨ (D ∧ !E) where a, b, c are integer variables and D, E are Boolean variables. Show all the steps in generating TBRO. Draw the abstract syntax tree (AST) and label the nodes N1 to Nm. Explicitly list the true and false constraint sets for each node in the AST. Remember to generate a test set TBRO corresponding to the root...
In aqueous solution, hypobromite ion, BrO-, reacts to produce bromate ion, BrO3 -, and bromide ion, Br-, according to the following chemical equation. 3 BrO-(aq) → → BrO3 -(aq) + 2 Br-(aq) A plot of 1/[BrO-] vs. time is linear and the slope is equal to 0.056 M-1s-1. If the initial concentration of BrO- is 0.80 M, how long will it take one-half of the BrO- ion to react?
