- Try Again Row 3: Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. A student runs two experiments with a constant-volume "bomb" calorimeter containing 1100. g of water (see sketch at right). First, a 7.000 g tablet of benzoic acid (CH₂CO₂H) is put into the "bomb" and burned completely in an excess of oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 kJ/g.) The temperature of the water is observed to rise from 15.00 °C to 53.26 °C over a time of 12.3 minutes. Next, 5.420 g of acetylene (C₂H₂) are put into the "bomb" and similarly completely burned in an excess of oxygen. This time the temperature of the water rises from 15.00 °C to 74.42 °C. Use this information, and any other information you need from the ALEKS Data resource, to answer the questions below about this reaction: Is this reaction exothermic, endothermic, or neither? If you said the reaction was exothermic or…arrow_forward3. A sample of glucose reacts in anaerobic respiration. The right-hand box below shows a particle diagram of the moles of substances present after the reaction is complete. On a piece of paper draw the "Before" box as shown and draw a particle diagram of the reactant molecules that produced the mixture shown on the right. Key Before = C₂H5OH = CO₂ = C6H12O6 After You will need to draw a diagram to answer this question. On a piece of paper, draw the "Before" box as shown, and then draw a particle diagram of the reactant molecules that produced the mixture shown on the right.
