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 C12H22011. ANS: the one test you can perform involves matches. NaCl is inorganic and will not burn, whereas C2H201 WILL burn because it is organic." Simple, yes? Now apply similar thinking to these pairs.

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,...

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?
Chemistry In a TLC experiment, three spots were made. In spot A was a crude sample of a mixture of three compounds ethyl 4- aminobenzoate (base), salicylic acid, and naphthalene as the neutral compound. In spot B, was just the neutral compound, naphthalene. In spot C was the pure compounds of spot A. When dipped with KMnO4, it is said that all spots should turn yellow, but while doing the experiment it was only the bottom compounds that turned yellow for me which I found out was the acid. Should all spots really turn yellow? Why would this happen?

Be sure to complete step ONE before moving on to the other steps. Break each step down. You should have four steps altogether. Consider a double replacement reaction between Zinc (ll) chloride and sodium hydroxide: ZnCl2+NaOH ==> Complete the chemical equation by: Step 1: Rewrite it to include electrically-neutral ionic product formulas for each formula. Hint for step 1: rewrite the entire equation including charges. For example, if Na + Cl2 ==> were your reactants, you would not predict NaCl2 as a chemical product because that is not an electrically neutral compound formula. Sodium chloride contains sodium ions, each with a +1 charge, and chloride ions, each with a -1 charge. Overall, the compound has no charge, because the positive sodiums balance out the charge on the negative chlorides, and vice versa. Step 2: Balance the equation. Step 3: Add subscripts (aq, I, s, or g) to show how the reactants combine and which product will precipitate to be collected as a solid.…

Citric acid (abbreviated H3Cit) is a triprotic acid, so 3 moles of hydroxide ions are required per mole of citric acid for complete neutralization. A.) Write the balanced chemical equation for the reaction of citric acid with sodium hydroxide.
