Answer:

anyywhere between 20-23 miles

Explanation:

it depends what type of oil field u mean

15,499 km is Louisville from the nearest oil field. Therefore, option A is correct.

An oil field is defined as a piece of land beneath which fossil fuels can be extracted for economic value. The world's oil is concentrated in oil fields found in the Middle East, along with other large deposits discovered beneath the ocean's surface.

Oil wells are classified into three different categories. Those that exclusively formed oil, those that exclusively formed natural gas and those that formed both oil and natural gas.

Petroleum supplies transportation fuel, is a part of many chemicals and medicines, and is used to create crucial items such as heart valves, contact lenses, and bandages. Oil reserves attract outside investment and are important for improving countries' overall economy.

Thus, 15,499 km is Louisville from the nearest oil field, option A is correct.

Your question is incomplete, most probably your question was

How far is Louisville from the nearest oil field?​

A.15,499 km

B.15,499 m

C.14,567 km

D.14,567 m

Answer:

2.45 m/s2

Explanation:

Newton's 2nd law tells us that force is equal to the mass of an object multiplied by its acceleration, or F = ma. We can solve this equation for acceleration by rearranging algebraically:

a = F/m

So:

a = (4.9N)/(2.0kg) = 2.45 m/s2

Explanation:

The percentage composition of iron (Fe) in Fe2(Cr207)3 can be calculated by finding the molar mass of Fe and the compound

Answer:

4Fe + 3O2→ 2Fe2O3

Explanation:

Fe + O2 → Fe2O3 is the unbalanced form of chemical reaction.

Balancing the simple molecules first, in this case the O2

Fe + 3O2→ Fe2O3 there are now 6 O atoms on the left, there must also be 6 O atoms on the right.

Fe + 3O2 → 2Fe2O3

Balance the rest of the equation.

4Fe + 3O2→ 2Fe2O3

Answer:

Multiply the element's atomic mass by the number of atoms of that element in the compound. This will give you the relative amount that each element contributes to the compound. For hydrogen chloride, HCl, the molar mass of each element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.

Answer:

Water is a human necessity. Therefore, it is one of the first things a human settlement would need to have. A community cannot thrive without a water source.

Answer:

Water is a basic need that is more than a necessity, humans can't survive without water for more than a period of three days, And thus having water as available, creates a tendency among humans as humans like to get everything at ease so they tend to settle near the water bodies if possible.

Newton's 2nd law tells us that force is equal to the mass of an object multiplied by its acceleration, or F = ma. We can solve this equation for mass by rearranging algebraically:

m = F/a

So:

m = (12.0N)/(5.0m/s2) = 2.4kg

Answer:

20ºCelsius

Explanation:

Answer:

A

Explanation:

The statement best describes solvation " KCl is surrounded by the polar water molecule to form an electrolyte solution which can conduct electricity."

The act of attracting and associating particles of a solvent mostly with molecules as well as ions of a solute would be known as solvation.

A material that contains ions and has been electrically conducting due to the mobility of the ions but still doesn't conduct electrons was called an electrolyte.

Whenever the solvent would be in the water, the process is referred to as hydration. The process of solvation shows the combination of solvent and solute molecules. A solute molecule is usually surrounded with solvent molecules that are organized in a special manner during solvation.

Therefore, the correct answer will be an option (A)
