= Magic Money = Ruby---Problem: How much solution of C3H7OH and H2O/water keep a piece of cloth from burning for at least a minute?

Ruby---Hypothesis: We Believe that more water and less solution will make the cloth from burning for a minute or more.

Melissa---Materials ~H2O (water) ~C3H7OH ~One piece of cloth ~Metal tongs ~Candle ~Beakers ~Stop Watch ~Graduated Cylinders ~Goggles

Melissa---Procedures: First we took one piece of cloth and cut it out into rectangle. Then we measured the amount of water and C3H7OH that we wanted to start with. We mixed the two solutions together, and with the piece of cloth that we cut out in the beginning, we then put it in the solution. Then we waited for a minute so the cloth absorbed the solution. While the cloth was in the solution, we lit up a candle. After the minute was over we then took it out of the solution and put the wet cloth on top of the candle while someone was holding it with tongs. We started the online stop watch and saw how long it took the wet cloth to burn.

Jalee---Observations

Jalee--Conclusions Our hypothesis was wrong because the solution we used only lasted for the most was 50 seconds. We figure out in the end that the the C3H7OH the actually coats the clothe from the fire but we thought it would make it even more burnable. 1. What type of reaction is taking place? Endothermic 2. Is a physical or chemical change taking place between the cloth and flame? Chemical Reaction 3. What elements are involved in the investigation? Carbon, Hydrogen 4. What type of mixture is being investigated? Homogeneous 5. What are some real-world applications for C3H7OH. For Construction for buildings, the fireman use it everyday to help put out a fire.
