A researcher attempts a substitution reaction with two different reagents, water or hydroxide ion, to see which route is better. Draw the major,
A 3.77g sample of oxalic acid (H2C2O4x2H2O) was dissolved in enough water to make 1000 mL of solution. Then 17.15mL of this oxalic acid solution was titrated to the end point with 22.05mL of an unknown sodium hydroxide soloution.
Explain why the balloon would float when heated. Make sure to discuss which factors change and which remain constant, and why this matters. Be complete.
hydrogen peroxide is used as a cleaning agent in treatment of cuts and abrasions for several reasons. In the laboratory, small quantities of hydrogen peroxide can be prepared by the action of an acid on an alkaline earth metal peroxide, such as ba..
