Liquid octane (CH3(CH,) CH,) reacts with gaseous oxygen gas (02) to produce gaseous carbon dioxide (CO2) and gaseous water (H,O). If 1.87 g of carbon dioxide is produced from the reaction of 8.0 g of octane and 7.6 g of oxygen gas, calculate the percent yield of carbon dioxide. Round vour answer to 2 significant figures.

Sodium (Na) is oftentimes confused by students with Salft (NaCl). They are different chemicals. Look over the MSDS sheets for both. In term of safety issues, how are they very different? (i.e why is it you will never get to see or touch sodium in our lab?)

O GASES Calculating partial pressure in a gas mixture Jacqueline A 5.00 L tank at 7.37 °C is filled with 18.2 g of chlorine pentafluoride gas and 3.28 g of boron trifluoride gas. You can assume both gases behave as ideal gases under these conditions. Calculate the mole fraction and partial pressure of each gas, and the total pressure in the tank. Round each of your answers to 3 significant digits. 圖 mole fraction: chlorine pentafluoride partial pressure: | atm mole fraction: boron trifluoride partial pressure: | atm Total pressure in tank: | atm Explanation Check O2021 McGraw-Hill Education All Rights Reserved Terms of Use Privacy Accessibility MacBook Air 山回

M Common Ethical D.. O THERMOCHEMISTRY Understanding the definitions of heat and work A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) From previous experiments, this chemical reaction is known to release 141. kJ of energy. The position of the piston is monitored, and it is determined from this data that the piston does 358. kJ of work on the system during the reaction. O exothermic Is the reaction exothermic or endothermic? O…
