Set Up Cornell Note OPEN TO: Next available right-hand page SET UP: Cornell note • Title: Hydrogen and Oxygen Reaction • Essential question: Which ratio of hydrogen and oxygen gas result in the biggest explosion and why? TIME: 2 minutes WHEN DONE: Make a prediction about ratios of H 2 to O 2

5/1 Reaction: Hydrogen and Oxygen EQ: Which ratio of hydrogen and oxygen gas result in the biggest explosion and why? In this demonstration, we will: • Collect H 2 gas in 2 -liter bottle in reaction between zinc and 3 M hydrochloric acid • Add O 2 from Oxygen tank • Test out best ratio of H 2 to O 2 to make the biggest explosion

THIS SUMMARY IS FOR A GRADE: SHOW ME WHEN DONE 5/1 Reaction: Hydrogen and Oxygen SUMMARY: The biggest explosion occurred using a ratio of ___ : ___ , hydrogen : oxygen. The reason for this is because of the balanced equation: _____ + _____ , there needs to be ____ hydrogen molecules for every ____ oxygen molecule to combine to make _______. If any different ratio is used, the explosion is _______, because_____________.

Sketch Zinc and Hydrochloric Acid: EQUATION: Zn (s) + 2 HCl (aq) Zn. Cl 2 (aq) + H 2 (g) - Immediate reaction, vigorous bubbles - Gas is visible, Zn turning black, heat produced Sketch Oxygen Gas From Oxygen Tank Hydrogen and Oxygen: Sketch EQUATION: 2 H 2 + O 2 2 H 2 O - Loud explosion, bottle shot across room - Bottle feels warm to the touch
