Find the percent by mass of oxygen in heptanoic acid, C6H13CO2H.
A gas has a volume of 50.0 cm3 at a temperature of -73 C. What volume would the gas occupy at a temperature of -123 C if the pressure stays constant?
The NaOH Solution with a concentration of .188M is used to titrate a diprotic acid of unknown concentration. 25.00 mL of the acid solution requires 26.54 mL of NaOH solution. What is the concentration of the acid solution
There are two reason why the enols of beta-dicarbonyl compounds, such as pentane-2,4-dione are relatively stable. One is that they are conjugated and the pi-electron overlap due to the conjugation provides additional stability.
