(Cristina) Observations- (Davis) Problem- (James) Hypothesis and Procedures- (Dayshondra) Conclusion-
Problem: Our problem is that we have to figure out the amount of solution needed to prevent the piece of cloth from burning. The solution consist of rubbing alcohol and water.



Hypothesis: We believe that if we put more isopropyl than water in a combination of the two, the cloth will last longer without burning.



Procedures:
Trial 1:
1: We measured out 50 mL of water
2 We measured out 10mL of isopropyl
3 We put the cloth in the mixture of water and isopropyl for 1 minute.
4 We took it out to early and failed this first trail


Trail 2:
1 We measured out 50 mL of water
2 We measured 10mL of isopropyl
3 We mixed the isopropyl and water
4 We put the cloth in the mixture
5 We pulled it out after 2 minutes and 40 seconds
6 It lasted 26 seconds without burning


Trail 3:
1 We measured out 50 mL of isopropyl
2 We then measured 25 mL of water
3 We mixed the isopropyl and water
4 We then left it in the mixture for 2 minutes and 30 seconds
5 We removed the cloth and put it over the flame
6 It lasted for 47 sec without burning


Trail 4:
1 We measured 25mL of water
2 We measured 25mL of isopropyl
3 We mixed the water and isopropyl
4 We put the cloth in the mixture for 1 minute and 30 seconds
5 We took it out and put over the flame
6 it lasted without burning for 1 minute and 8 seconds


Trail 5:
1 We measured 20 mL of water
2 We measured 30 mL of isopropyl
3 We mixed the water and isopropyl
4 We put the cloth in the mixture for 1 minute and 40 seconds
5 We put it over the flame
6 It lasted without burning for 51 seconds


Trail 6:
1 We measured 40 mL of water
2 We measured 10 mL of isopropyl
3 We mixed them together
4 We put the cloth in the mixture for 5 minutes
5 It lasted without burning for 1 minute and 17 seconds



Trail 7:
1 We measured 50mL of water
2 We measured 12mL of isopropyl
3 We mixed the substances
4 We put the cloth in the mixture for 3 minutes.
5 We put it over the flame
6 It lasted for 1 minute and 1 second



Observations:
(First Trial) Failed.
1. On the first trial we started over because we left the money hanging. The problem was that we didn't have a flame burning, so we started over because we noticed that some of the solution had leaked.
(Second Trial) Failed. 26 Seconds
2. On the second trial, we did not fold the piece of money too much. We only folded it in half. The piece of money was in the solution for about two minutes and fourty seconds.
(Third Trial) 47 Seconds. Failed.
3.On the third trial, the sharpie ink was running off of the money, that might of affected the time the piece of money burned.
4. While we put the piece of money on the flame, it shot up quickly but did not burn right away.
5. The same amount of water and isopropyl was mixed. It didn't catch on fire as quick as we thought it would.
(Fourth Trial) Failed.
5. On our fourth trial, It lasted for 1 minute and 8 seconds.
6. We added more isopropyl than we did water.
(Fifth Trial) 51 seconds Failed.
7. The flame shot up high at first but then came back down.
8. We left the piece of money in their for about a minute and thirty seconds. That might be the reason for why it didn't last as long.
(Sixth Trial) 1 Minute & 17 Seconds.
9. A few flakes came off of the tong and onto the solution.
10. We folded the piece of money four times, that might of effected the way it lasted longer.


Conclusion:
Our hypothesis was was wrong because our longest time was 1 minute and 14 seconds, and as you see in the procedures in the 6th trial we had more water than Isopropyl. The type of reaction was exothermic. It was a chemical change. The elements used were hydrogen oxygen carbon. The mixer was heterogeneous. Sine real-world applications for C3H7OH is using it to make fire proof money.
