1. What is the value of fire detection and suppression systems in all types of occupancies? Have you seen these type of systems in use and how have they assisted in a fire situation? 2. You are the lieutenant of a fire company and are assigned to conduct a preplan on the site of a new Type I high-rise that is currently under construction. As you preplan the building, please explain the advantages and disadvantages of this construction type and how it makes your job easier, or more difficult, in the event of an emergency. Your response should be at least 200 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations. 3. Compare and contrast steel and concrete construction including the fire resistance properties of each. Understanding the construction principles as well as the fire resistance properties of each construction type, what is your mindset from a tactical approach to the mitigation of a fire at these occupancies in order to avoid the hazards associated with these buildings? Your response should be at least 200 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.
(111) A hypothetical element xylo(symbol Xy) forms four different compounds with another hypothetical elemnent phone(symbol Ph). Using the old nomenclature, write the empirical formula for each compound. (a) xylo monophonide (b) dixylo triphonide (c) dixylo tetraphonide (d) xylo diphonide (112) Using the formulas from question 111, dtermine the oxidation values for Xy and Ph and rename the compounds according to the Stock System. (Hint: First, use the empirical formula for dixylo triphonide to determine the oxidation number of Ph. The oxidation number for Ph is the same for the other compounds.) (a) (b) (c) (d)

014 (part 1 of 2) 10.0 points Magnesium hydroxide is 54.87% oxygen by mass. How much oxygen is in 156 g of the compound? Answer in units of g. 015 (part 2 of 2) 10.0 points How many moles of oxygen is this? Answer in units of mol.
Copper (II) nitrate reacts with sodium sulfide to produce sodium nitrate and copper (II) sulfide in this reaction. How many grams of NaNO3 are produced from the reaction of 2.44 moles of Cu(NO3)2
A. percent yield = (actual yield / theoretical yield) × 100% B. The theoretical yield is the amount of product that can be made based on the amount of limiting reactant. C. The limiting reactant is completely consumed in a chemical reaction. D. The actual yield is the amount of product actually produced by a chemical reaction. E. All of the above are true statements.
