Try Again Your answer is incorrect. (CH3)2CO: Your answer is incorrect. • ZnBr2: Your answer is incorrect. The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H₂O). Note: "major" chemical species are those present in concentrations greater than 10 compound acetone iron(III) chloride zinc bromide formula (CH,),CO FeCl3 Zn Br₂ major species present when dissolved in water (CH,),O, H,O 3+ H₂O, Fe³+, Cl¯ 2+ H₂O, Zn²+, 2 Br 7² × mol/L. 0,0,...

This last question is different. Just because it is different doesn't make it hard. It's actually very easy. However, you DO have to know simple properties of molecules. Using simple tests, describe one single thing you can do to each pair of compounds in order to tell which is which. ALL YOU ARE ALLOWED TO USE IS: Matches, Water, Dilute NaHCO3, Dilute HCI, and Dilute NaOH. To help you, here is an example of the question, as well as the approach/thought process: "DESCRIBE ONE SINGLE TEST YOU COULD USE TO DIFFERENTIATE BETWEEN NaCl AND C12H2m011. ANS: the one test you can perform involves matches. NaCl is inorganic and will not burn, whereas C12H22O1 WILL burn because it is organic." Simple, yes? Now apply similar thinking to these pairs.

Ammonia (Hydrogen Nitride) is harmful to our cells (no duh right?) but our body naturally makes a little bit of this chemical through its natural processes. In order to get rid of this poisonous substance, our cells secrete ammonia into the blood stream to be combined with carbon dioxide. In this process, urea (CN2OH4) and water is made. Urea is less toxic to our bodies and is secreted into our urine. If a total of 32.54g of ammonia is secreted into the blood stream and 61.48g of urea is secreted in our urine, what is the percent yield of this reaction?
