Answer: The distance of the earth from the sun is 
Explanation:
Speed of light = 
Time taken to travel from sun to earth = 8.30 mins = 
(1min=60 s)
As we know ; Speed is defined as the distance travelled per unit time.
Hence distance between sun and earth =
Thus the distance of the earth from the sun is
Answer:
50distance and 10minutes time

because it's the best object
Answer:
One gallon of octane produces approximately 7000 L of carbon dioxide.
Note:
I believe that the mass of octane should have been given as 2661 g. However, I understand that your instructor probably gave you this problem, so I will use 4000 g for the approximate mass of one gallon of octane. You can rework the problem on your own, substituting the correct masses of octane if you wish.
Step1. You must first determine the number of moles that are in 4000 g of octane, using the molar mass of octane. Step 2. Then you must determine the number of moles of carbon dioxide that can be produced by that number of moles of octane, based on the mole ratio between octane and carbon dioxide in the balanced equation. Step 3. Then use the ideal gas law to determine the volume in liters of carbon dioxide that can be formed.
