Question 4 - Combustion of Octane 0/2 points Cars run on gasoline, where octane (C8H18) is the principle component. This combustion reaction is responsible for generating enough energy to move a vehicle, or do other work. How much co, and H2O (in grams) are produced in the combustion of 1.14 gallons of Octane? (density = 0.703 g/mL) Start with a balanced equation for this combustion reaction! Helpful conversion, there are 4 quarts in a gallon. Beyond that, check out your...

The heat of combustion of heptane and isooctane are -4501 kJ/mol and -5100 kJ/mol, respectively. Isooctane (2,2,4-trimethylpentane, pronounced iso-octane) is a pretty good model for the complex mixture of hydrocarbons that is gasoline. The density of these two liquids (essentially the same for all liquid hydrocarbons) is 0.7 g/mL (kg/dm3). What is the heat of combustion of one gallon of the two liquids? Are they essentially the same or quite different? Why? a. b. The U.S. Congress (our representatives) mandated...

1. a. The car I drive is a Toyota Prius C; its average mileage rating is 52.0 mpg. Convert this rating into units of kilometers traveled per liter of gasoline consumed. (3 pts) b. Gasoline is a mixture of several hydrocarbon compounds, but let's assume that it consists of only one: octane. If the density of octane is 0.703 g/mL, use the result from part a to calculate how many kilometers the Prius C can travel on one kilogram of...

Problem 1 - Strontium Hydroxide Acid/Base Question -/1 points A 8.51 mL sample of nitric acid required 13.25 mL of 0.105 M strontium hydroxide for titration. Calculate the molarity of the acid solution. (Hint: It's stoichiometry, you need the balanced equation) Concentration of Nitric Acid M Evaluate Problem 3 - H2Z Molecular Weight -/1 points A solution was made by adding water to 0.22 g of H2Z until the volume totaled 25.00 mL. Subsequent titration required 40.50 mL of 0.11...
