Both Japan and the United States import many of their fossil fuels from other countries. Based on what you know about fossil fuel formation, why do you think fossil fuels are not distributed evenly across the globe?

Answers

Answer 1

Answer:

Fossil fuels are formed when living organisms die, and are buried under a tick layer of earth materials over a long time, usually over million s of years. Fossil fuels are formed under intense heat and pressure on the dead organisms due to the earth layer that has accumulated on the organisms over the years. The type of fossil fuels formed in a particular region depends on the type of organism that has lived in that region over the years, and the climate of the region. Regions with lush, swamp forests with many trees have enough  organic material to make coal over the years. The United states however still depend on the importation of other fossil fuel that are in minimal quantity in the country. Most regions have coal, because they once had forests and animals on them but countries like the United States and some other countries have them in abundance, because these regions had a huge amount of lush, swamp forests with many trees. Japan lacks significant domestic reserves of fossil fuel, except coal, and must import substantial amounts of crude oil, natural gas, and other energy resources, because of its climate and the fact that it is an island nation.

Answer 2

Fossil fuels are distributed unevenly because their formation requires precise conditions that aren’t found everywhere. For fossil fuels to form, they need to be subjected to anoxic (lacking oxygen) conditions that allow for great pressure, such as those found beneath the ocean floor.nation:

If 50.0cm3of a saturated solution of KNO3at 40oC contained 5.05g of the salt. What is the solubility of the salt at 40oC? [KNO3=101].

Answers

Answer:

The solubility of KNO₃ at 40° C is 1 mol/dm³

Explanation:

The solubility of a substance is the number of moles of that substance (solute)  contained in a unit volume of solvent at that particular temperature.

Now, Solubility = n/V where n = number of moles of KNO₃ and V = volume of saturated solution = 50.0 cm³ = 0.05 dm³

n = m/M where m = mass of KNO₃ = 5.05 g and M = molar mass of KNO₃ = 101 g/mol

n = 5.05 g/101 g/mol = 0.05 mol

Solubility = n/V

= 0.05 mol/0.05 dm³

= 1 mol/dm³

So, the solubility of KNO₃ at 40° C is 1 mol/dm³

The molecules move more quickly and their average kinetic energy decreases.
The molecules move more slowly and their average kinetic energy increases.

Answers

Answer:

The molecules move more slowly and their average kinetic energy decreases

Explanation:

The increased temperature meant that the atoms in liquid had a greater average energy of motion so as the temperature decreases the reaction would be inverse.

The branch of science which deals with the chemicals bond is called chemistry.

The correct option is B.

The energy which is produced by the motion of the particles is called kinetic energy. Temperature increases the motion of the particles. So, the kinetic energy increases when the temperature rises.

According to the question, the temperature of the water decreases therefore the kinetic energy decreases.

Hence, the correct option is B that is the molecules move more slowly and their average kinetic energy decreases.

For reaction: 2 C + O2 --> 2 CO2 If 5.50 g C was reacted with enough O2, what would be the volume (in liter) of the CO2 generated at STP? (0 C and 1 atm)

Answers

Answer:

10.2 L of CO₂

Explanation:

Our reaction is:

2C + O₂  →  2CO₂

We convert the mass of C, to moles:

5.50 g / 12g/mol = 0.458 moles

Ratio is 2:2, so if 2 moles of C can produce 2 moles of CO₂ then 0.458 moles of C would produce 0.458 moles of gas.

By the Ideal Gases Law, we know that 1 mol of gas is contained in 22.4L, so:

0.458 mol . 22.4L / 1mol = 10.2 L

In an experiment, 125ml of H2 is collected over water at 27C and barometric pressure of 753 torr. the vapor pressure of water at 27C is 26.74 what is the partial pressure of H2?

Answers

Answer:

Partial pressure of H₂ = 0.9556 atm

Explanation:

Given:

Barometric pressure = 753 torr

Vapor pressure of water = 26.74 torr

FInd:

Partial pressure of H₂

Computation:

Partial pressure of H₂ = Barometric pressure - Vapor pressure of water

Partial pressure of H₂ = 733 - 26.74  

Partial pressure of H₂ = 726.26 torr

1 atm = 760 torr

So,

Partial pressure of H₂ = 726.26/760

Partial pressure of H₂ = 0.9556 atm

MARKING BRAINLIEST!! - Determine the molar mass [MM] of a gas if 2 L of the gas weights 0.500 g at 298 K and 2.00 atm.

Answers

Answer:

3.125g/mol

Explanation:

To find the molar mass of the gas, we need to initially find the number of moles (n) contained in the gas. To find the number of moles, we use the general gas law whose equation is:

PV=nRT

Where; P= Pressure

V= Volume occupied by gas

n= number of moles

R= general gas constant

(0.0821 L atm mol/K)

T= absolute temperature

According to the question; P= 2.0atm, V= 2.0L, n= ?, T= 298K

To find n, we make it the subject of the formula:

n= PV/RT

n= 2.0 × 2.0 / 0.0821 × 298

n= 4/ 24.4658

n= 0.16mol

If number of moles (n) of the gas is 0.16mol and it weighs 0.500g, its molar mass can be found using:

number of moles (n) = mass (g) / molar mass

Making MM subject of the formula;

molar mass = mass / number of moles

MM= 0.500/0.16

MM= 3.125

Hence, the molar mass of the gas is 3.125g/mol.

Magnesium unites completely and vigorously with oxygen to form magnesium oxide, which contains 60% magnesium by weight. If 1.00 gram of magnesium is sealed in a glass tube with 1.00 gram of oxygen, what will be present in the tube after the reaction has taken place

Answers

Answer:

After the reaction, there will 0.60 g of magnesium oxide and 0.25 g of oxygen gas present in the tube

Explanation:

Equation of the reaction between magnesium and oxygen is given as follows:

2Mg(s) + O₂(g) ---> 2MgO(s)

From the equation of reaction, 2 moles of magnesium reacts with i mole of oxygen gas to produce 1 mole of magnesium oxide

molar mass of magnesium is 24.0 g; molar mass of oxygen gas = 32.0 g; molar mass of magnesium oxide = 40.0 g

Therefore 24 g of magnesium reacts with 32 g of oxygen gas

I.00 g of magnesium will react with (24.0 / 32.0) * 1.00 g of oxygen = 0.75 g of oxygen gas.

Therefore, magnesium is the limiting reagent. Once it is used up, the reaction will stop and the excess oxygen will be left in the tube together with the product, magnesium oxide.

mass of excess oxygen = 1.00 - 0.75 = 0.25 g

mass of magnesium oxide formed = (24.0 / 40.0 g) * 1 = 0.60 g

Answers

Answer:

36.1%

Explanation:

The following data were obtained from the question:

Mass of hydrated copper sulfate = 2 g

Mass of anhydrous copper sulfate = 1.278 g

Percentage of water =..?

Next, we shall determine the mass of water in the hydrated copper sulfate.

This can be obtained as follow:

Mass of hydrated copper sulfate = 2 g

Mass of anhydrous copper sulfate = 1.278 g

Mass of water =...?

Mass of water = Mass of hydrated copper sulfate – Mass of anhydrous copper sulfate

Mass of water = 2 – 1.278

Mass of water = 0.722 g

Finally, we can obtain the percentage of water in the hydrated copper sulfate as follow:

Mass of water = 0.722 g

Mass of hydrated copper sulfate = 2 g

Percentage of water =..?

Percentage of water = mass of water /mass of hydrate x 100

Percentage of water = 0.722/2 x 100

Percentage of water = 36.1%

Therefore, the percentage of water in the hydrated copper sulfate is 36.1%

2 C5H10(1) + 15 O2(g) →10 CO2(g) + 10 H20 (8)

Answers

Answer:

266 liters Carbon iv oxide will be formed

Explanation:

The first thing we need to do here is to calculate the number of moles of oxygen reacted.

This can be calculated using the ideal gas equation;

Mathematically;

PV = nRT

From the question;

P = pressure = 10.5 atm

V = volume = 400 liters

n = number of moles = ?

T = temperature = 125 + 273 = 398K

R = molar gas constant = 0.0821 L•atm•K^-1•mol^-1

Substituting these values, we have ;

n = PV/RT

n = (10.25 * 400)/(398 * 0.0821) = 125 moles

From the question;

15 moles oxygen gave 10 moles CO2

125 moles oxygen will give x moles CO2

x = (125 * 10)/15 = 83 moles

Now, we want to know the volume of CO2, present in 83 moles using the given reaction conditions.

Mathematically;

PV = nRT

V = nRT/P

= (83 * 0.0821 * 398)/10.25 = 265.65 which is approximately 266 Liters
