Solution Steps

Step 1: Find the number of valence electrons for Sulfur.

Sulfur (S) is in group 16 (also known as group VIA) of the periodic table. Elements in this group have 6 valence electrons.

Step 2: Account for the -1 charge.

The -1 charge on the sulfide ion (S⁻¹) indicates that it has gained one extra electron.

Step 3: Total valence electrons.

Therefore, the S⁻¹ ion has 6 (original valence electrons) + 1 (added electron) = 7 valence electrons.

Step 4: Lewis Dot Structure.

The Lewis dot symbol shows the element symbol surrounded by dots representing the valence electrons. Since S⁻¹ has 7 valence electrons, the Lewis dot symbol will have 7 dots around the symbol "S".

Which of the following are true statements about the pizza delivery times? (Select all that apply.) About 68% of deliveries are between 24 and 32 minutes. On average, a delivery taking less than 26 minutes is equally as likely as a delivery taking more than 30 minutes. On average, a delivery taking less than 25 minutes is more common than a delivery taking more than 35 minutes. About 95% of deliveries are between 20 and 36 minutes.

Let f(x) = (x^2 - 1) / (x - 1) (a) Make tables of the values of f at values of x that approach x0 = -1 from above and below. Then estimate the limit as x approaches -1 of f(x). (b) Support your conclusion in part (a) by graphing f near x0 = -1 and using Zoom and Trace to estimate y-values on the graph as x approaches -1. (c) Find the limit as x approaches -1 of (x^2 - 1) / (x - 1) algebraically. (a) Complete the table given below.

Researchers wanted to test the effectiveness of a new cognitive behavioral therapy (CBT) compared with both an older behavioral treatment and a placebo therapy for treating insomnia. They identified 75 adults with insomnia. Patients were randomly assigned to one of three treatment groups. Twenty-five patients were randomly assigned to receive CBT (sleep education, stimulus control, and time-in-bed restrictions), another 25 received muscle relaxation training (RT), and the final 25 received a placebo treatment. Treatment lasted 6 weeks, with follow-up conducted at 6 months. To measure the effectiveness of the treatment, researchers used wake time after sleep onset (WASO). CBT produced larger improvements than did RT or placebo treatment. For example, the CBT-treated patients achieved an average 55% reduction in their WASO, whereas RT-treated and placebo-treated patients, respectively, achieved only 17% and 13% reductions in this measure. Results suggest that CBT treatment leads to significant sleep improvements within 6 weeks, and these improvements appear to endure through 6 months of follow-up. Answer parts (a) through (f) below. (a) What type of experimental design is this? A. Completely randomized design B. Matched-pairs design C. Cohort study D. Randomized block design
