Properties of Gases

Heather Schnicker 26 October 2012 Experiment 4 (Lab 3) Properties of Gases PURPOSE The social function of this investigate was to investigate and identify the chemical properties of the liquides tested. DATA Gas FLAME reply GLOWING SPLINT LIMEWATER REACTION BROMOTHYMOL BLUE REACTION Hydrogen NO REACTION Oxygen BURNED BRIGHTER Hydrogen & Oxygen quickly FLAME BURST Carbon Dioxide PUT THE FIRE OUT NO REACTION TURNED YELLOW Alka Seltzer BUBBLED Breath HUGE BUBBLES CONCLUSIONBased complete this experiment it made me realize that the responses are such(prenominal) more disparate when comparing an virulent or basic solution. By doing these experiments at firm also proves a point in that knowing what type of counterbalanceion to expect is a must. QUESTIONS A. Give two reasons why we fill the gas generator test tubes almost to the top with chemicals. * To get as much gas as possible without any air * Some of the chemicals could react with the type O that is fil ling up the rest of the test tube B. What happens to the atomic number 30 in the hydrogen generation experiment? * It dissolvesC. What happens to the manganese in the oxygen generation experiment? * The manganese acted as a catalyst D. draw up a balanced equation for the reaction between 02 and H2? -H2 + H2 +02= 2H20 E. What is the function/purpose of the bromothymol blue in the C02 experiment? -To show how acidic solutions react differently than basic solutions E. Bromothymol blue is blue in the presence of basic solutions, and colour in the presence of acidic solutions. If your solution is a murky green, what superpower you assume about a solution? -It is a mixture of acidic and basic solutions
