CH4 O2 CO2 H2O. The combustion of methane is an important reaction in our daily lives, as it is used to generate electricity and cook food. So, if they both equal the same amount of H2O created, which one would be considered my liming reagent? 0000003656 00000 n We now have 4 O atoms on both sides. methane + oxygen carbon dioxide + water Total mass of reactant consumed = (4 + 16) g = 20 g According to the Law of Conservation of Mass, total mass of products = 20 g Mass of water produced = (20 - 11) g = 9 g. Copyright@Qingdao ECHEMI Digital Technology Co., Ltd. ), Reacting 12 g of C with 32 g of O2 to form 44 g of CO2. (Assume the product of the reaction includes the mass of any unused reactants. This represents the reaction of hydrogen and oxygen gas to form water. The reactants are CH4 and 2O2. Mass of PCl3 ( actual yield) = 35.0 g What is the mass % of sulfur in aluminum sulfate (Al2(SO4)3) rounded to three significant figures? They are not balanced. @Sanya: Don't get too personal. 2CH4 + 4O2 2CO2 + 4H2O write a balanced reaction for this reaction. How do I ask homework questions on Chemistry Stack Exchange? NH4Cl NH3 + HCl 4. H2O - Water, oxidane A: We have given that Discuss whether or not this reaction obeys the law of conservation of mass. Okay, so for home work i was given this problem. Now look at the O atoms. Clearly the methane is the reagent in deficiency, and why is this an appropriate circumstance? Answer (1 of 4): Chemical reaction equations operate on "mols" of elements and compounds. 3 answers; chemistry; asked by Janaiby trailer << /Size 158 /Info 136 0 R /Root 139 0 R /Prev 110953 /ID[] >> startxref 0 %%EOF 139 0 obj << /Type /Catalog /Pages 137 0 R /OpenAction [ 140 0 R /XYZ null null null ] /PageMode /UseNone >> endobj 156 0 obj << /S 173 /Filter /FlateDecode /Length 157 0 R >> stream The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. Is there a detailed equipment manufacturing plan and tables of important nodes, inspection items and standards. If you burn 40.0 grams of methane in a counter that contains 128.0 grams of oxygen, how much . Combination reactions There are 4 H atoms on the left side and 2 H atoms on the right. Calculate his cardiac result. All redox reactions are combustion reactions. Which contains more carcinogens luncheon meats or grilled meats? 4) PbCO3 (s) PbO (s) + CO2 (g), Which of the following general reactions appropriately models a combination reaction? Why don't objects get brighter when I reflect their light back at them? The products are CH4 and 2H2O. Therefore, CH4 will be left as it is the reagent in excess. After you have fully debugged this function, define another function that takes a single argument, which is an array that contains a string value and that reverses the spelling of the string value in the array argument. CH4 + O2 -> CO2+2H20 Predict the products of the chemical reaction and explaining why you made this prediction. For the reaction Na + H2O NaOH + H2, what are the reactants, products, and correct coefficients in the balanced equation? For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Since the coefficients of CH4 and CO2 are both 1, it means that every one mole of CH4 consumed, one mole of CO2 is produced. Why is balancing chemical equations important. Fourth, you produce 1 H2O for every O2, or 0.1875 moles of H2O which weighs 3.375 grams (=0.1875 moles x 18 grams/mole). What is the percentage of nitrogen, by mass, in calcium nitrate? Start your trial now! The balanced equation is CH4(g)+2O2(g)CO2(g)+2H2O(g) In the burning reaction, methane (CH) reacts with oxygen (O) to produce carbon dioxide (CO) and water (HO): CH + 2 O CO + 2 HO This reaction obeys the law of conservation of mass because nothing was created or destroyed just rearranged. 0000000873 00000 n Propane - C 3 H 8. For chemical reaction CH4(g) + O2(g) CO2(g) + H2O(g), CH4(g) and O2(g) are called reactants and CO2(g) + H2O(g) are called products, CH4(g) and O2(g) are called products and CO2(g) + H2O(g) are called reactants. Your final answers were correct. Step 1: Write a balanced equation. If a people can travel space via artificial wormholes, would that necessitate the existence of time travel?
