- Calculate the amount of carbon dioxide (in kg) emitted into the atmosphere by the complete combustion of a 15.0 gallon tank of gasoline. Do this by following these steps: Assume that gasoline is composed of octane (C8H18). Write a balanced equation for the combustion of octane. Determine the number of moles of octane contained in a 15.0 gallon tank of gasoline (1 gallon = 3.78 L). Octane has a density of 0.79 g/mL. Use the balanced equation to convert from moles of octane to moles of carbon dioxide, then convert to grams of carbon dioxide, and Finally to kg of carbon dioxide.arrow_forwardInsoluble AgCl(s) precipitates when solutions of AgNO3(aq) and NaCl(aq) are mixed. AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq) rH = ? To measure the energy evolved in this reaction, 250. mL of 0.16 M AgNO3(aq) and 125 mL of 0.32 M NaCl(aq) are mixed in a coffee-cup calorimeter. The temperature of the mixture rises from 21.15 C to 22.90 C. Calculate the enthalpy change for the precipitation of AgCl(s), in kJ/mol. (Assume the density of the solution is 1.0 g/mL and its specific heat capacity is 4.2 J/g K.)arrow_forward1 ! QUESTION 10 The metabolism of one glucose with six oxygens to form six carbon dioxides and six waters releases 678 kcal per mole of glucose. Given this, which statement below is true? O Glucose metabolism is endothermic and the energy of the products (CO2 and H2O) are lower than the reactants (glucose and O2) O Glucose metabolism is endothermic and the energy of the products (CO2 and H₂O) are higher than the reactants (glucose and O2) O Glucose metabolism is exothermic and the energy of the products (CO2 and H2O) are higher than the reactants (glucose and O2) O Glucose metabolism is exothermic and the energy of the products (CO2 and H2O) are lower than the reactants (glucose and MacBook Pro C G Search or type URL A Q A K 2 W S #3 E D $ 4 R F do LO % 5 T 6 G Y & 7 H ☆ U * 00 8 9 O J Karrow_forward

- Which diagram above represents a chemical reaction that releases energy (exothermic)? How do you know? Which diagram above represents a chemical reaction that absorbs energy (endothermic)? How do you know? What does the hump in the middle of each diagram represent?arrow_forwardQuestion 15 of 16 *3 # E D C C Carbohydrates serve as a vital source of chemical energy to the human body. Carbohydrates are broken down into smaller units of glucose, among other sugars, providing energy to various muscles and organs, including the brain. On average, for every 10.0 g of carbohydrates consumed, the body will store 170 kJ of energy.
