Hi, I'm Jessica And today, I'm going to be talking about a chemical demonstration I like to call Money to Burn and chemist Dr. Balsam Shakhashir

here he is actually going to be showing us the deem He's the president of the American Chemical Society and is performing this demo right here at MIT

Let's see if he has some money to burn What I'm going to do now I I'm going to reach in here, I'm going to take a dollar bill and I'm going to put it into flame just like that

Was that too fast? What we always do in science is repeat the experiment So I think although it looks like a dollar bill it's not a real dollar bill

I bring it close to the flame It disappears into thin air. It looks like magic, right? I love magi Magic is engaging

but not informative How is that dollar bill burning up so quickly? Well, it's actually not a dollar bill It's called flash paper

And it's paper that has been treated with chemical to make it burn quickly and leave no ashes Now flash paper has been nitrate Practically what that means is that

you soak the paper in a mixture of concentrated nitric and sulfuric acid The cellulose in the paper then reacts with the ace to produce nitrated cellulose and water The reaction is this

So our nitric acid her mixes with the cellulose Now this is actually just one unit in the big polymer that is cellulose It's got lots of little units of C6H10O5

So in this equation, I'm only writing one unit And that's creating nitrated cellulose and water Now the nitro group, the NO2, is the reactive group and it can be very reactive depending on the molecule that it's in
