If you have a white powder that could be either Epsom salt or table salt, how could you decide which one it is?
Predict its structure by drawing the most stable dehydration product that could result after a single carbocation rearrangement of the intermediate?
None of the desired ether was obtained. What product was formed and why did this route to the ether fail? Suggest a different substitution reaction that should yield the desired product.
An important reaction in the formation of photochemical smog is the photodissociation of NO2: NO2 + hv >>> NO(g) + O(g) The maximum wavelength of light that can cause this reaction
Assuming 100% dissociation, calculate the freezing point and boiling point of 2.72 m AgNO3(aq).
calculate the initial reaction rate when [O3] & [NO] remain essentially constant at the values [O3]0= 7.48 x 10-6 M & [NO]0= 3.26 x 10-5M, owing to continuous production from separate sources.
Deduce the structure of the molecule with the molecular formula C3H6 with a C13 NMR delta peak value of 27.8
Ethanol (without catalyst) yields a di-ether in nearly quantitative yield. Provide the structure of the product. Mechanistically, provide two routes that accound for the observed product.
What volume (in liters) of 1.04 M KOH solution should be added to a 0.090 L solution containing 9.3 g of glutamic acid hydrochloride (Glu, FW=183.59; pKa1=2.23, pKa2 =4.42, pKa3=9.95) to get to pH 9.90?
The molar heat of fusion of water is 6.01 kj/mol. How much heat energy is required to melt one ice cube in a soft drink to form liquid water a 0 degree celcius, if the ice cube has a mass of 18.9 g?
4HCl + MnO2 = MnCl2 + 2H2O + Cl2 When 1.22 mol of HCl reacts with excess MnO2, how many moles of Cl2 form?
