Chemistry

During reflux, you oxidized ethanol to acetic acid, usingpostassium dichromate.

A) How many grams of ethanol can be oxidized by 100.00mL of a0.750M K2Cr2O7 solution?

B) In a similar reaction, a chemist oxidizes methanol(CH3OH) to formic acid (HCOOH), also usingK2Cr2O7. Starting with halfreactions, write a balanced redox equation for the reactionperformed by the chemist. Show all steps
