Compare the behavior of the mixture of gases with each solitary gas in the presence of f lame. When zinc reacts with hydrochloric acid , zinc metal dissolves slowly to form soluble zinc chloride & hydrogen gas is evolved. 1. 5. Did the reaction between the antacid tablet and the tap water produce hydrogen, oxygen, or carbon dioxide gas? The tooth pick glowed followed by a popping sound and then the flame went out. Your email address will not be published. Reaction That Occurs When Magnesium Is In Contact With Hydrogen Peroxide ? When the smoldering toothpick came into contact with oxygen, it started burning again and slowly went out. The calcium carbonate was produced as a salt which turned the solution into cloudy precipitate, which shows that CaCO3 is not soluble in water. Did the BT B indicate presence of an acid or base? 2 Lime water turned cloudy with a precipitate. Write a chemical equation for the reaction of CO and limewater (Ca(OH) ). 2 2 Fizzing and bubbling and water is being displaced into hydrogen gas.

Write a balanced chemical equation describing the reaction of zinc and hydrochloric acid. The limewater turned cloudy with a precipitate. 2. Lab #4: Properties of Gases Exercise 1: Gas and Flame Tests Data Table 1. Save my name, email, and website in this browser for the next time I comment. CO2 reacted with Ca(OH)2 to produce CaCO3. Copyright 2019 – Hands-On Labs | http://holscience.com 3 / 6. Copyright 2019 – Hands-On Labs | http://holscience.com 2 / 6. 1. 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. A mixture of gases produce less amount of heat and solitary gases produce a high amount of heat. The acid is H2CO3 carbonic acid. why must the reaction between zinc and hydrochloric acid be carried out in a fume hood and away from naked flame? When air is exhaled in limewater, it turns slightly cloudy ; which shows carbon dioxide gas; which is what we exhale when we breath out. Copyright 2019 – Hands-On Labs | http://holscience.com 4 / 6, Step 1: CH3COOH (aq) + NaHCO3 (s)—>CH3COONa (aq) + H2CO3 (l), CH3COOH(aq) + Na2CO3(s) —> CH3COONa(aq) + CO2(g) + H2O(l). Write a physical description of the products formed. How did this gas behave in the presence of f ire? 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. The precipitate in the test tube turned a brownish color. 2 CO2 gas put out the flame on the toothpick quickly with a little re lease of smoke. Gas Observations. The flame went out. Bubbled quickly and started to rise to the top.Gas is being released in the form of bubbles. What happened when the smoldering toothpick came into contact with the gas? What gas was produced by the decomposit ion of hydrogen peroxide? In the presence of fire, hydrogen explodes with a popping sound. With the smoldering toothpick you heard a popping sound. Step/Reaction Observations (24 bookmarks) Exercise 1: Gas and Flame Tests Data Table 1. Copyright 2019 – Hands-On Labs | http://holscience.com 6 / 6. The color change indicates the presence of an acidic substance. Flame on the toothpick went out quickly releasing a little bit of smoke. The toothpick glowed and was reignited. A chemical reaction occurred where the gas was released quickly. The reaction between the antacid tablet and the tap water produces carbon dioxide gas. Using this writing service is legal and is not prohibited by any university/college policies. Gas Observations. Our products include academic papers of varying complexity and other personalized services, along with research materials for assistance purposes only. 4. Hydrogen gas is flammable but it requires oxygen to ignite. Oxygen mixed with hydrogen; when exposed to a flame made a popping sound. The precipitate did not dissolve in the solution. The flame test in Exercise 1 with hydrogen peroxide produced a popping sound the flame reignited. The popping sound put out the flame. The decomposition of hydrogen peroxide produces oxygen gas. Hydrogen also exists in stars and planets. The gas that was produced by the reaction of zinc and hydrochloric acid was Hydrogen gas and zinc chloride. In the presence of fire, hydrogen explodes with a popping sound. The gas produced is hydrogen, it burns with a popping sound. Required fields are marked *. The gas that was produced by the reaction of zinc and hydrochloric acid was Hydrogen gas and zinc chloride. 2 The blue color solution (BTB) change to yellow. Question: Exercise 1: Gas And Flame Tests Data Table 1. Gas Observations. 2 2 Fizzing occurred and the lime water turned cloudy with precipitate. Based on your observation of the reaction that occurred when limewater was exposed to your breath, what gas did you exhale? Step 1: _____ + _____ → CH COONa(aq) + H CO (aq), Ca(OH)2 (aq) + CO2 (g) —>CaCO3 (s) + H2O (l). 3. The hydrogen gas that zinc and hydrochloric acid produce has many uses. Support your answer with results f rom your work in both Exercise 1 and Exercise 2. Oxygen Gas + Smoldering toothpick […] The reaction took place when a fizzing of CO2 gas released. © 2020 Smart Academic Experts. 3. It has no taste, color or odor, and is one of the least-dense gases. Reaction that occurs when magnesium is in contact with hydrogen peroxide ? On Earth, it is present in water and in molecules that form living organisms. 2. Copyright 2019 – Hands-On Labs | http://holscience.com 5 / 6, Data Table 2: Carbon Dioxide Reaction Observations. Hydrogen is one of the most abundant elements in the universe, and it plays a role in many daily life functions. Step/Reaction Observations Reaction Between Zinc And Hydrochloric Acid ? Hydrogen Gas + Flame ? In the presence of CO2 gas, the flame was put out on the toothpick quickly. SmartAcademicExperts: a professional writing service that provides original papers. Hydrogen serves many practical uses in society because it is versatile and fairly easy t… 4. Cloud of water vapor and gas. What gas was produced by the reaction of Step/Reaction Observations Reaction between zinc and hydrochloric acid ? Exercise 1: Gas and Flame Tests Data Table 1. The decomposition of hydrogen peroxide produced Oxygen.
