combustion of acetylene lab answers

In the course of the combustion analysis of an unknown compound containing only carbon, hydrogen, and nitrogen, 12.923 g of carbon dioxide and 6.608 g of water were measured. Consider the combustion reaction for acetylene. Combustion of Acetylene Reaction of Calcium Carbide with Water Continued on page 2 Introduction Use this demonstration at the start of the school year or in your unit on chemical reactions. Acetylene is a hydrocarbon also known as ethyne (C 2 H 2). This is probably not a complete answer, but it must be noted that under compression acetylene can undergo an exothermic dimerizattion to form vinylacetylene. (Use grams moles) 2.46 g H2O × 1 mol H2O Explain. Explain. In this lab we will produce acetylene by placing calcium carbide (CaC2) in water. The acetylene in this lab will be collected in a test tube and burned. The acetylene in this lab will be collected in a test tube and burned. Treatment of the nitrogen with H 2 gas resulted in 2.501 g NH 3. We filled multiple test tubes with acetylene gas at different levels, and then put flame near it to make a combustion reaction. 4 CO2 + 2 H2O. 2.What is being varied between each test tube/trial? UNIT 9 STOICHIOMETRY / 9.3 LIMITING REACTANT AND PERCENT YIELD 9.3 Combustion of Acetylene lab Analysis Assignment In this lesson we watched a laboratory demonstration video showing the production and combustion of ethene (acetylene) gas. The balanced equation for the combustion of acetylene is 2 H2C2 + 5 O2 ? Write the balanced equation for the combustion of acetylene. The safe, controlled explosion gives you the opportunity to answer “Yes” to a question that Calcium chemistry students often ask, “Are we + 10H+ 13O 2 C 4 H 10 2 8CO 2 2 O a. F. Acetylene (Ethyne) Mixture Observations Tube 1 Tube 2 Tube 3 Tube 4 Table 4: Results - Acetylene 1.What is required to be present in order for combustion to occur? We need to write a balanced eqn for each situation. 2. Note the coefficients of the reactants. 5.Would you expect acetylene (ethyne) to react with bromine with or without exposure to light? For this assignment, we will look more closely at the chemical reactions involved in terms of the limiting reactant and percent yield in this analysis. Write the balanced equation for the combustion of acetylene. 2. Complete combustion reactions are known to form carbon dioxide and water as products. In this lab, we will be determining the ratio of acetylene to oxygen that gives complete combustion. 3. 3. In the reaction 2 H2C2 + 5 O2 ? The complete combustion of 11.014 g of the compound needed 10.573 g of oxygen. 2C2H2(l) + 5O2(g) mc001-1.jpg 4CO2(g) + 2H2O(g) If the acetylene tank contains 37.0 mol of C2H2 and the oxygen tank contains 81.0 mol of O2, what is the limiting reactant for this reaction? Write the chemical formula for the reaction between calcium carbide and water knowing that the product is acetylene (C2H2). Explain. What proportion of oxygen molecules to acetylene molecules are required for the most effective burning of acetylene… It is a gas often used in welding. Look at the balanced equation. In our lab, we made a combustion reaction using acetylene. How many moles of water are produced? 1. The combustion of a sample of butane, C 4 H 10 (lighter fluid), produced 2.46 grams of water. Repeat steps 1 to 8 for each of the other two amounts of acetylene. A combustion reaction occurs when a compound merges with oxygen to release heat in an exothermic reaction. From there other hydrocarbons can form. 3. Neglect of this possibility might lead to errors in the analysis. I get that the eqn is: _C2H2 +_O2 -- _C+ _CO+ _CO2+_H2O But im not sure how to balance the equation because in our lab we first used a full test tube of acetylene, and then we used half a test tube and then 1/3 of a test tube of acetylene and lastly 1/12 of a test tube of acetylene.
