Fill in the blanks with the correct form of the passato prossimo. Be sure to use the appropriate auxiliary verb (essere or avere) and the correct past participle. Remember: Passato prossimo is a compound tense consisting of two parts: an auxiliary verb and a past participle. For reflexive verbs (those with “si” in their infinitive form), a reflexive pronoun (mi, ti, si, ci, vi, si) is required. Una giornata al mare Ieri, Lucia e i suoi amici [1] (andare) al mare per passare una giornata insieme. [2] (Partire) presto la mattina e [3] (prendere) il treno per arrivare alla spiaggia. Appena arrivati, [4] (mettere) i loro asciugamani sulla sabbia e sono andati subito in acqua, perfetta per nuotare. Dopo una lunga nuotata, gli amici [5] (decidere) di fare una passeggiata lungo la spiaggia. Loro [6] (fare) foto dei bellissimi panorami. Più tardi, [7] (mangiare) in un ristorante vicino alla spiaggia dove [8] (assaggiare) specialità di pesce fresco. Nel pomeriggio, io [9] (giocare) a pallavolo e Leo [10] (rilassarsi) sotto il sole, Maria [11] (guardare) il tramonto. [12] (Essere) una giornata fantastica e tutti [13] (divertirsi) molto!

a. Draw the Lewis structure for CBr2S (This structure should be shown on your scratch paper sent to Dr. Metz – show ALL STEPS for this process) b. What is the electron domain number for the central atom in CBr2S ? (This answer must be included in this exam below – on Canvas) c. What is the molecular geometry for CBr2S ? (This answer must be included in this exam below – on Canvas) d. What are the predicted bond angle around the central atom for CBr2S ? If applicable, what impact do the lone pair of electrons or multiple bonds have on the predicted bond angle between the fluorine atoms? (This answer must be included in this exam below – on Canvas) e. What is the hybridization of the central atom in CBr2S ? (This answer must be included in this exam below – on Canvas)

Which of the following best illustrates the ethical principle of Accountability in system design?

In the reading, “What educated citizens should know about statistics and probability”, Utts argues that several statistical concepts are commonly misunderstood by both the public and even researchers themselves. Choose one of the seven topics mentioned in the article that the author identifies as a source of confusion and describe it in your own words. Then, discuss a potential consequence of this misunderstanding (within a specific scientific discipline or society more broadly). How might scientists (and lifelong students of science like you) be able to reduce misunderstandings of the topic you chose? These are open-ended questions, so feel free to discuss whatever comes to mind while keeping your discussion on topic.

Which of the following statements best describes Cloud Computing?

Which phase of the cardiac action potential can be altered by hypomagnesemia? 

These medications are prescribed for the relief of acute pain, postoperative pain, and/or chronic pain.

Which of the following practices primarily contributes to ensuring the correctness of a system?

a. Step 1 in constructing a Lewis structure is to calculate the number of valance electrons available. How many valance electrons are available in the following molecular formula, CO3-2 ? (This answer must be included in this exam below – on Canvas) b. Step 2 in constructing a Lewis structure is to identify the central atom and draw single bonds between the central atom and all non-central atoms. Show the process and resulting intermediate Lewis structure for this step below for CO3-2 . (This intermediate structure should be shown on your scratch paper sent to Dr. Metz) c. How many valence electrons are represented after Step 2 (part b)? How many valance electrons remain to complete the Lewis structure? (This answer must be included in this exam below – on Canvas) d. Step 3 in constructing a Lewis structure is to place nonbonding electron pairs around all non-central atoms to complete their octet. Show the process and resulting intermediate Lewis structure for this step below for CO3-2 . (This intermediate structure should be shown on your scratch paper sent to Dr. Metz) e. How many valence electrons are represented after Step 3 (part c)? How many valance electrons remain to complete the Lewis structure (This answer must be included in this exam below – on Canvas) f. Step 4 in constructing a Lewis structure is to place all remaining valence electrons as nonbonding electron pairs on the central atom. If there are no remaining valence electrons use multiple bonds to complete the octet of the central atom. Show the process and the resulting final Lewis structure for CO3-2 below. (This structure should be shown on your scratch paper sent to Dr. Metz)
