Question- In a nitration of phenol which will yield p-nitrophenol and o-nitrophenol, why doesn't meta nitration occur for phenols?
I have no idea how to do this! Thank you for your help!
Problem- Calculate the pH of a solution that is 0.295 M in sodium formate (NaHCO2) and 0.205M in (HCO2H)- The Kb of formatic acid is 1.77x10^-4.
Calculate the amount of heat transferred when 45.0 g of CH3OH(g) is decomposed by this reaction at constant pressure.
How is the concentration of Cl determined by mercuric nitrate? Is there a color change at various levels? (similar to the Cl test for swimming pools and you'd have to match a particular color to a particular concentration?)
Ben Franklin dropped the oil on the surface of a lake and found that 2 mL of oil gave a circle of radius 30 m. Estimate the volumetric size of an oil molecule in angstroms, give one significant digit.
