Answer: 61.44 barrels of crude oil are required to run your car for a year.
Step-by-step explanation:
A barrel of crude oil has a volume of 42 gallons, only approximately 45% of which is processed into gasoline. This means that the processed gasoline from 1 barrel of crude oil would be
45/100 × 42 = 18.9 gallons
If your car achieves 31 mi/gal, and you drive 36,000 miles in one year, it means that the number of gallons of gasoline that you would require in a year is
36000/31 = 1161.29 gallons of gasoline
Since 1 barrel of crude produces 18.9 gallons of gasoline, then the number of barrels of crude that would produce 1161.29 gallons of gasoline would be
1161.29/18.9 = 61.44 barrels
The ball will have kinetic energy because the released the potential and kinetic is taking over.
The “twins” is telophase then going up from there is interphase, prophase,metaphase, anaphase and then back to telophase (where I started at)
i just learnt this recently but i need to look through my notes again.
<u>Answer:</u> The change in entropy for the system is 140.3 J/K
<u>Explanation:</u>
The chemical equation follows:
To calculate the entropy change for vaporization of methanol, we use the equation:
where,
= entropy change of the reaction
n = number of moles = 1.00 mole
= heat of vaporization = 35.21 kJ/mol = 35210 J/mol (Conversion factor: 1 kJ = 1000 J)
T = temperature of the system =
Putting values in above equation, we get:
Hence, the change in entropy for the system is 140.3 J/K
