Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 9.1 g of octane is mixed with 22.7 g of oxygen.
Consider the titration of 100.0 mL of 0.100 M HNO3 by 0.200 M NaOH.Calculate the pH after 34.5 mL of NaOH has been added.At what volume (in mL) of NaOH added does the pH of the resulting solution equal 7.00.
In relation to the previous question, diazonium salts couple with phenols in slightly alkaline solution. What effect does the pH of the solution have on the reactivity of the phenol?
50.0 mL of a 1.70 M solution is diluted to a volume of 248 mL. A 124-mL portion of that solution is diluted using 185 mL of water. What is the final concentration
Determine the mass of propylene glycol neded to substitute one gallon of ethylene glycol and also find out the volume of propylene glycol, required to get the same antifreeze protection as one gallon of ethylene glycol.
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.
Using a solution prepared by adding 467 mL of 0.400 M silver nitrate with 421 mL of 0.503 M sodium phosphate then determines what is the silver ion concentration in? Ksp of silver phosphate = 2.8 × 10-18
Boron often forms compounds that do not comply with the octet rule that are termed electron deficient. BF3, whose structure is shown below on the left, is an example of an electron deficient compound.
