- The balanced equation for the combustion of butane, CAH10, is shown below. For your convenience, the molar mass of each substance is shown below their formulas (in purple). Use this information to make the requested calculation: 2 CAH10(g) + 13 02(g) --> 8 CO2(g) + 10 H20(1) 58.124 32 44.011 18.016 How many liters of oxygen gas would be necessary to burn 18.2 g of butane?arrow_forwardButane, C4H10C4H10, reacts with oxygen, O2O2, to form water, H2OH2O, and carbon dioxide, CO2CO2, as shown in the following chemical equation: 2C4H10(g)+13O2(g)→10H2O(g)+8CO2(g)2C4H10(g)+13O2(g)→10H2O(g)+8CO2(g) The coefficients in this equation represent mole ratios. Notice that the coefficient for water (10) is five times that of butane (2). Thus, the number of moles of water produced is five times the number of moles of butane that react. Also, notice that the coefficient for butane (2) is one-fourth the coefficient of carbon dioxide (8). Thus, the number of moles of butane that react is one-fourth the number of moles of carbon dioxide that you produce. But be careful! If you are given the mass of a compound, you must first convert to moles before applying these ratios. Calculate the mass of water produced when 9.81 gg of butane reacts with excess oxygen.

- Up [References] Ethanol, the alcohol used in automobile fuels, is produced by the fermentation of sugars present in plants. Corn is often used as the sugar source. The following equation represents the fermentation of glucose, the sugar in corn, by yeast to produce ethanol and carbon dioxide.

- The human body burns glucose (C6H₁2O6) for energy according to this chemical reaction: C6H₁206+60₂-6CO₂ + 6H₂O The products of the reaction are carbon dioxide (CO₂) and water (H₂O). Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500. mL of air, which is typically enriched to 4% CO₂ and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.8 kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 3.00 kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO₂ is 2.0 kg/m³. 0 Xarrow_forwardMethane and hydrogen sulfide react to form hydrogen and carbon disulfide, like this: CH4(g)+2H2S(g)→4H2(g)+CS2(g) Use this chemical equation to answer the questions in the table below.arrow_forwardCoal is a leading source of energy for the world. While coal is primarily composed of carbon and hydrogen, a small amount of sulfur is also present. This leads to the production of pollutants such as sulfur dioxide (SO2) through the following reaction: S(s)+O2(g)→SO2(g) A sample of coal was found to contain 1.35% sulfur by mass. If 1,250 kg of this coal were burned, what mass of sulfur dioxide could theoretically be formed (in kg)?arrow_forward
