An organic compound has a molecular formula C6H12O2. Its IR spectrum shows a strong carbonyl absorption band near 1740 cm-1. Its H-NMR spectrum shows ONLY two singlets. Propose a structure that is consistent with these data.
assuming the end units will be Molarity as well. 13.1mL of AgNo3 solution are reacted with excess Na2CO3 solution to form AgCO3 precipitate. If 5.62mg of Ag2CO3 are formed, what was the original concentration
The other criterion is very basic and relates to whether simple or fractional is selected
When the Vmax and the Km of an enzyme are not known, it is essential to determine the enzyme's initial velocity (Vo) at different [S]. To determine the initial velocity, one would have to: Select one: a. Use the Michaelis Menten equation
Ethyl acetate liquid (flask with ethyl acetate with the top cover with aluminium paper with small whole in the top and inserted inside hot water container) Was the vapor really "ideal". If not, how were calculations affected
Would the pH of a 0.10 M formic acid (HCOOH) solution be higher or lower than the pH of a solution containing 0.10 M formic acid and 0.10 M sodium formate
curved arrows to symbolize the flow of electrons, white the stepwise mechanism for the acid-catalyzed esterification of p-aminobenzoic acid to ethyl p-aminobenzoate
What is the total pressure, in mmHg, of a gas mixture containing argon gas at 0.25 atm, helium gas at 350 mmHg, and nitrogen gas at 360 torr
If 25 g of al and 100g of br2 are reacted and if 64.2 grams of aliminum bromide is formed. what is the theoretical yield
Safrole is used as a topical antiseptic. Calculate the vapor pressure of a solution prepared by dissolving 0.75 mol of safrole in 950 g of ethanol ( molar mass = 46.07 g/mol). P°ethanol = 50.0 torr at 25°C
Draw the major, neutral organic product for each substitution reaction below
25.0 mL of a hydrofluoric acid solution of unknown concentration is titrated with 0.200 M NaOH. After 20.0 mL of the base solution has been added, the pH in the titration flask is 3.00. What was the concentration of the original hydrofluoric acid ..
How do you know whether it is talking about the concentration of the OH in MgOH2 or NH3, cuz they give different answers and apparently they are using NH3 not mgoh2
