It's important to know that many chemical reactions are _____. That is: For example, under certain conditions, one mole of the colourless gas N2O4 will decompose to form two moles of brown NO2 gas: N. 2. O. 4 . 2 NO. 2. colourless brown. Under other conditions, you can take 2 moles of brown NO2 gas and change it into one mole of N2O4 gas: N. 2. O. 4 . 2 NO

  • into one of the pipettes until it is partly up the bulb, using the pipette filler. Swirl the solution Swirl the solution around then empty the pipette over the sink.

  • 1) In a series of quick reactions, glucose (which is alkaline) is converted into glucoside, and oxygen gas in the flask is shaken into solution. The dissolved oxygen oxidizes the methylene blue (which begins colorless when reduced) turning it blue (oxidized). Then, slowly the blue colored oxidized methylene blue is reduced by the glucoside and the solution turns back to colorless.
