Chemistry lab question:   Part C: Using table 1, identify the unknown base *l have included part a and b, which includes the pOH and Kb. I will also attach table 1.

Need both of these!!!

Check the box next to each molecule on the right that has the shape of the model molecule on the left: model + molecules (check all that apply) □ CH₂ Cl H₂O₂ O NH CH₂O You can molecu Give detailed Solution .don't give Handwritten answer

Compared my ao values for NH4Cl=4.143 angstrom and ao values for NaCl = 5.996 angstrom to the literature values ao of NH4Cl = 3.88 Angstrom and ao = 5.64 angstrom.   Can you please explain any reason for this including uncertainties.

Please help! I need to know how to draw the full chemical structure of isoproyl red.  *I drew the structure of isopropyl alcohol (second pic) but was told this was incorrect and that the chemical structure needs to show a combination of methyl red and isopropyl alcohol.

Organic Functional Groups Identifying positions labeled with Greek letters in acids and derivatives If possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ß carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. HO. Oneither substituent can be added.

4. Start with NH3 and show step-by-step how the compound N-sec-butyl-N-isopropyl-3-pentanamine can be formed. Draw and name the reactants and products in each reaction (3 separate reactions.) 5. Salicylic acid (shown below) is a polyfunctional molecule (contains more than one functional group.) Circle and identify the functional groups on salicylic acid. Salicylic acid can react with ethanoic acid (acetic acid) to form aspirin. It can also react with ethanol to form ethyl salicylate, a compound with a minty smell used in perfume and artificial flavors. Draw out structures to illustrate each of these reactions. Discuss how these two reactions are similar and how they are different. HO, HO
