When the bromothymol blue (BT B) was exposed to the CO gas, what color was the solution? The gas produced is hydrogen, it burns with a popping sound. Did the BT B indicate presence of an acid or base? Gas Observations. The popping sound put out the flame. 2 CO2 gas put out the flame on the toothpick quickly with a little re lease of smoke. Hydrogen Gas + Flame ? The acid is H2CO3 carbonic acid. The precipitate in the test tube turned a brownish color. In the chemical reaction that occurs between the antacid tablet and water produces carbon dioxide which was shown by the bubbles that put out the flame completely. Lab #4: Properties of Gases Exercise 1: Gas and Flame Tests Data Table 1. In the presence of fire, hydrogen explodes with a popping sound. On Earth, it is present in water and in molecules that form living organisms. 4. Step/Reaction Observations (24 bookmarks) Exercise 1: Gas and Flame Tests Data Table 1. When air is exhaled in limewater, it turns slightly cloudy ; which shows carbon dioxide gas; which is what we exhale when we breath out. Support your answer with results f rom your work in both Exercise 1 and Exercise 2. 2 The blue color solution (BTB) change to yellow. In the presence of CO2 gas, the flame was put out on the toothpick quickly. Fill in the missing information for the chemical equation. 2 2 Fizzing occurred and the lime water turned cloudy with precipitate. Outline the procedures you would use to determine whether a gas sample was composed of hydrogen or oxygen. 2. 2. The flame test in Exercise 1 with hydrogen peroxide produced a popping sound the flame reignited. Hydrogen also exists in stars and planets. Hydrogen gas is flammable but it requires oxygen to ignite. The gas that was produced by the reaction of zinc and hydrochloric acid was Hydrogen gas and zinc chloride. A chemical reaction occurred where the gas was released quickly. What happened when the smoldering toothpick came into contact with the gas? T he chemical equation for the reaction of baking soda (sodium bicarbonate, NaHCO ) and vinegar (acetic acid, CH COOH) may be written as two steps. What gas was produced by the reaction of A mixture of gases produce less amount of heat and solitary gases produce a high amount of heat. Write a physical description of the products formed. The precipitate did not dissolve in the solution. The gas that was produced by the reaction of zinc and hydrochloric acid was Hydrogen gas and zinc chloride. The popping sound put out the flame.
