What are 3 theoretical reaction mechanisms that can occur with bromine addition to trans-cinnamic acid. The last mechanism accounts for a mixture of syn and anti products
A 195mg sample of a non-electrolyte isolated from throat lozenges was dissolved in enough water to make 10.0mL of solution at 25 degrees Celsius. The osmotic pressure of the resulting solution was 4.83atm. Calculate the molar mass of the compound.
Octane has a density of 0.692 g/mL at 20 degrees Celsius. How many grams of O2 are required to burn 1.00 gal of C8H18?
A 7.75-L container holds a mixture of two gases at 37 °C. The partial pressures of gas A and gas B, respectively, are 0.209 atm and 0.735 atm. If 0.130 mol a third gas is added with no change in volume or temperature, what will the total pressure ..
Classify each of the following compounds as ionic or molecular. If it is ionic, classify it as a Type I or Type II ionic compound. CoCl2, CF4, BaSO4, NO
