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.
What do you mean by an oil field ?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.

Consider the atomic model of the element chlorine. Which elements will bond ionically with chlorine such that the formula would
be written as XCL2?
-0
A)Hydrogen
B)Magnesium
C)Oxygen and Sulfur
D)Lithium and Sodium
E)Barium and Calcium
Answer:
it is magnesium and barium and calcium
Magnesium, Barium, and Calcium will bond ionically with chlorine such that the formula would be written as MgCl₂, BaCl₂, and CaCl₂.
What are ionic compounds?Ionic compounds can be explained as crystalline solids which are formed by packing of opposite charge ions due to the interactions of the ions. An Ionic compound is produced when metal reacts with non-metal.
In ionic compounds, oppositely charged ions are held by ionic bonds due to the interactions between ions. The ions are formed from atoms by gaining or losing electrons in order to attain their noble gas configuration.
A cation in ionic compounds is the electropositive ion and has the tendency to give away valence electrons. Similarly, anions in ionic compounds are electronegative ions and have a tendency to gain electrons.
The chlorine needs one electron to complete its valence shell. Therefore two chlorine will combine with a divalent cation. Therefore Magnesium, Barium, and Calcium exist as Mg⁺², Ba²⁺ , and Ca²⁺.

A wooden plank has a mass of 100kg force of 20 n was used to move it what is its acceleration
Answer:
a= 0.2m/s²
Explanation:
Fnet = ma
20 = 100a (divide both sides by 100)
a = 0.2m/s²
A wooden plank has a mass of 100 kg force of 20 Nwllhave the acceleration of 0.2 m/s².
What is Acceleration ?Acceleration is the rate of change of the velocity of an object with respect to time.
Accelerations are vector quantities.
The orientation of an object's acceleration is given by the orientation of the net force acting on that object.
We know,
F= ma ,
where
F is force , M is mass , A is acceleration.For 100kg ,
20 = 100 x A
A = 20/100
A = 0.2 m/s².

How many moles of O2will be produced from 6.2 moles of water?
Answer:
I hope This will help you....and please mark me as Brilliant
Explanation:
The formula, H2O tels us that there are the same number of moles of Oxygen as there are of water. The (understood )molecular coefficient of H2O is 1. The (understood ) coefficient of O in the formula is also 1. The number of moles of oxygen is the same as the number of moles of water. This is moles of oxygen atoms. If the question wants moles of oxygen gas, O2, then it will be half as many I think that is what they want, so I would answer 3.1 moles of O2.

How many moles of sodium are required in order to produce 5 moles of
sodium chloride?
Answer:
5 moles of Sodium are required to produce 5 moles of Sodium Chloride.
Explanation:
I am assuming you were not given an equation and this is a synthesis reaction.
Let's begin by writing a balanced chemical equation for the synthesis of sodium chloride.
2Na⁺ + Cl₂⁻ -> 2NaCl
Since Cl₂ exists as a diatomic molecule, we must have 2 +1 charges from Na to balance out the 2 -1 charges of Cl₂ (-1 for each Cl atom). This will then form 2 moles of NaCl.
To produce 5 moles of sodium chloride, we can multiply the entire equation by 2.5. This will result in:
5Na⁺ + 2.5Cl₂⁻ -> 5NaCl
The stoichiometric ratios of this new equation is:
5 Na: 2.5 Cl₂: 5NaCl
5 moles of sodium (Na) are required to produce 5 moles of sodium chloride (NaCl).

4NO + 3O2 + 2H2O = 2.4 moles of NO 2.4 moles of O2 and 2.4 moles of H2O react and 2.0 moles of HNO3 are recovered from the reaction. what is the percent yield of this reaction ?
Answer:
83%
Explanation:
Percent yield is 100 times the ratio between actual yield (2.0moles HNO₃) and theoretical yield. To find theoretical yield:
As you can see in the reaction:
4NO + 3O₂ + 2H₂O → 4HNO₃
4 moles of NO are required when 3 moles of O₂ and 2 moles of H₂O reacts. As equal moles of each reactant are added, the limiting reactant is NO because is the substance that requires more moles to react.
2.4 mol NO produce 2.4 mol HNO₃-Because 4 moles of NO produce 4 moles of HNO₃. That means theoretical yield is 2.4 moles and percent yield is:
2.0 moles / 2.4 moles * 100 = 83%

How are air temperature and humidity related? Colder air can hold more water vapor than warmer air. Warmer air and colder air can hold the same amount of water vapor. Warmer air can move faster than colder air. Warmer air can hold more water vapor than colder air.
Answer:
Warmer air can hold more water vapor than colder air.
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time.
The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object (body).
On the other hand, humidity refers to the concentration (amount) of water vapor that is present in the air. It is high when there's a lot of water vapor in the air and low when the level of water vapor is small.
The relationship between air temperature and humidity is that warmer air can hold more water vapor than colder air because as the air cools, its molecules move closer together while the molecules move farther apart as the air become hot.
Additionally, at constant humidity, relative humidity is inversely proportional to temperature i.e as the temperature decreases, relative humidity increases.

Why is it not advisable to light a charcoal stove in limited supply of oxygen.
Answer:
Due to the limited supply of oxygen, carbon (ii) oxide, a poisonous gas, is produced instead of carbon(iv) from the burning charcoal stove and this may result in death when inhaled.
Explanation:
When charcoal is burnt in a plentiful supply of oxygen, the combustion products is carbon (iv) oxide (carbon dioxide) which is not very toxic to the human body. The equation of the reaction is given below:
C + O₂ ----> CO₂
However, in a limited supply of oxygen gas, the combustion product is carbon (ii) oxide. The equation of the reaction is given below:
2C + O₂ ----> 2CO
Carbon (ii) oxide is a colorless and odorless gas which unlike carbon (iv) oxide is very toxic to human and results in fatality when inhaled in even small doses for a few minutes. Its mechanism of action of toxicity is that it competes with oxygen for transport in the body by hemoglobin. It combines irreversibly with hemoglobin to form carboxyhemoglobin, thereby depriving tissues and cells the oxygen they need. This results in death of the cells and tissues as well as of the whole organism. Thus, it is not advisable to light a charcoal stove in limited supply of oxygen.

Suppose 17. g of sulfuric acid is mixed with 7.07 g of sodium hydroxide. Calculate the maximum mass of sodium sulfate that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.
Answer:
ok let me study into this first
Explanation:
I'll answer this in a few
Answer:
Maas of sodium sulphate produced = moles×molar mass=0.06×142=8.52 gmoles\times molar\ mass=0.06\times 142=8.52\ gmoles×molar mass=0.06×142=8.52 g
Explanation:
Reaction between them is given by-
2NaOH +H2SO4 → Na2SO4 +2H2O2NaOH\ \ +H_2SO_4\ \to\ Na_2SO_4\ \ +2H_2O2NaOH +H2SO4 → Na2SO4 +2H2O
Molar mass of H2SO4=98 g mole−1H_2SO_4=98\ g\ mole^{-1}H2SO4=98 g mole−1
Moles of sulphuric acid taken = 5.8898=0.06 mole\frac{5.88}{98}=0.06\ mole985.88=0.06 mole
Moles of sodium hydroxide taken = 6.240=0.155 mole\frac{6.2}{40}=0.155\ mole406.2=0.155 mole
here sulphuric acid is limiting agent so
reaction will proceed according to sulphuric acid
