It protect the body from heat and other harmful substances.

It is comprises of three layers;

The Epidermis which is the outer layer.

The dermis which is a fibrous later that protect the Epidermis.

The subcutis is the subcutaneous layer that is beneath the dermis.

A nuclear power plant produces huge amount of electricity. However, it dumps radioactive wastes into the sea. This has led to an increase in illness among people living along the coast. Which of these is the best method to solve this problem?
Question 1 options:

Convert the nuclear power plant into a hydroelectric power plant which does not produce wastes.

Shift the nuclear power plant to locations far away from the sea.

Increase public awareness to close the nuclear power plant.

Provide the nuclear power plant with a plan to properly dispose of and recycle the wastes.

Answers

Answer: Provide the nuclear power plant with a plan to properly dispose of and recycle the wastes.

Explanation:

The nuclear power plant is producing huge amounts of electricity which is beneficial to the economy as it pushes growth. Shutting it down or relocating it is therefore not the right solution.

The problem is the radioactive waste being produced so a solution that is specific to this problem should suffice. That solution would be the provision of the nuclear plant with plans to properly dispose of the waste.

Should this happen, the nuclear plant can still stay in the same area and keep contributing to economic growth without adversely affecting people's heath.

The density of a gas is 1.26 g/L at STP. What is the mass of 1 mole? What could this gas be?

Answers

Answer: Molar mass=28.224g/mol, The gas could be Nitrogen gas

Explanation:

Density is calculated as  Molar mass/ Molar Volume

Recall that

One mole of an ideal gas at (STP) standard temperature and pressure = 22.4 liters (in Volume)

Given That Density =1.26 g/L

Volume = 22.4L at STP,

Molar mass = Density x Molar Volume

= 1.26 g/L x 22.4L =28.224g

Therefore, if  1  mole of this gas has a mass of 28.224g  then  its molar mass is equal to 28.224g/mol

The molar mass of Nitrogen =  28.014 g/moL, so we can conclude the the gas could be Nitrogen

The correct answer is (C)

Which is "1-fluorobutane"

Explanation:

Hope this helped if so please leave a "Rating" and "Like" and MARK me Brainliest if it was the BEST answer! THANKS! :)

The name of the hydrocarbon CH3CH2CH2CH2F is 1-fluorobutane.

In naming organic hydrocarbons, we count the number of the parent chain family. Here, we have an alkane with 4 carbons, which means that the parent chain is a family of alkane. The fourth compound in the family of an alkane is butane.

Afterwards, we will determine if there is any substituent attached to any of the carbon atoms in the chain and rank them in a way such that we have the lowest possible number.

Here, the fluorine is attached to the first carbon atom. So, it becomes 1-fluorobutane.

A 700 mL sample of gas at STP is compressed to 300 mL, and the
temperature is raised to 100.C. What is the new pressure of the gas in atm?

Answers

Answer:

P₂ =  3.19 atm

Explanation:

Given data:

Initial volume = 700 mL

Initial pressure = 1 atm

Initial temperature = 273K

Final temperature =100°C (100+273= 373 K)

Final volume = 300 mL

Final pressure = ?

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

P₂ = P₁V₁ T₂/ T₁ V₂  

P₂ = 1 atm × 700 mL × 373K / 273 K ×300 mL  

P₂ = 261100 atm .mL. K   /81900 K .mL

dipole dipole bonds are covalent bond?​

Answers

Answer:

The polar covalent bond is much stronger in strength than the dipole-dipole interaction. The former is termed an intramolecular attraction while the latter is termed an intermolecular attraction. So now we can define the two forces: Intramolecular forces are the forces that hold atoms together within a molecule.

Explanation:

I have some things to point out:

#1: There is no such thing as "Dipole-dipole bonds", only Dipole-dipole interactions between molecules that share an unequal balance of electrons between their atoms.

#2: Intermolecular forces of attraction such as Dipole-dipole interactions are not considered as covalent bonds. Covalent bonds are rigid and are considered intramolecular forces of attraction (found within the molecule instead of between)

What is 797 mm hg to atm?

Answers

Answer:

797 mm hg = 1.04868 atm

Explanation:

1 atm = 760 mm hg

797 mm hg to atm is 1.0468 atm

Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area.

There are many different types of units and prefixes that may be used in general practice to reflect pressure. Thus, it is ensured that all the measurements and their respective units are in the same framework when conducting pressure calculations.

Pascal is the SI unit of pressure, and is the basic pressure unit in the SI (the International System of Units) system.

Given,

Pressure = 797 atm

For the following reaction, calculate how many moles of each product are formed when 4.05 g of water is used.

2 H2O → 2 H2 +02

Answers

Answer:

A. 0.225 mole of H₂

B. 0.113 mole of O₂.

Explanation:

We'll begin by calculating the number of mole in 4.05 g of water (H₂O). This can be obtained as follow:

Mass of H₂O = 4.05 g

Molar mass of H₂O = (2×1) + 16 = 2 + 16 = 18 g/mol

Mole of H₂O =?

Mole = mass /Molar mass

Mole of H₂O = 4.05 / 18

Mole of H₂O = 0.225 mole

Next, the balanced equation.

2H₂O —> 2H₂ + O₂

From the balanced equation above,

2 moles of H₂O produced 2 moles of H₂ and 1 mole of O₂.

A. Determination of the number of mole hydrogen produced.

From the balanced equation above,

2 moles of H₂O produced 2 moles of H₂.

Therefore, 0.225 mole of H₂O will also produce 0.225 mole of H₂.

B. Determination of the number of mole oxygen produced.

From the balanced equation above,

2 moles of H₂O produced 1 mole of O₂.

Therefore, 0.225 mole of H₂O will produce = (0.225 × 1)/2 = 0.113 mole of O₂.

Thus, 0.113 mole of O₂ is produced.

How many grams of water will be produced when 1.6 moles of ethanol (CH3CH2OH) are burned completely? Enter a number only (no units) and express your answer using the correct number of significant figures.

Answers

Answer:

86

Explanation:

The reaction that takes place is:

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

First we convert moles of ethanol to moles of water:

1.6 mol ethanol * [tex]\frac{3molH_2O}{1molEthanol}[/tex] = 4.8 mol H₂O

Then we convert moles of water to grams of water, using its molar mass:

4.8 mol H₂O * 18 g/mol = 86.4 g

So 84.6 grams of water will be produced.

The mass of water, H₂O produced when 1.6 moles of ethanol, C₂H₅OH are completely burned is 86.4 g

We'll begin by writing the balanced equation for the reaction. This is given below

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

From the balanced equation above,

1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.

Next, we shall determine the number of mole of H₂O produced by the reaction of 1.6 moles of C₂H₅OH

From the balanced equation above,

1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.

Therefore,

1.6 moles of C₂H₅OH will react to produce = 1.6 × 3 = 4.8 moles of H₂O.

Finally, we shall determine the mass of 4.8 moles of H₂O.

Mole of H₂O = 4.8 moles

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass of H₂O =?

Mass = mole × molar mass

Mass of H₂O = 4.8 × 18

Mass of H₂O = 86.4 g

Thus, the mass of water obtained from the reaction is 86.4 g

c) Record the balanced chemical equation on the Student Worksheet.

Answers

Answer:

Propane gas plus oxygen gas produces water and carbon dioxide.

Explanation:

This is the initial chemical equation: C3H8 + O2 = CO2 + H2O

This is the balanced chemical equation: C3H8 + 5 O2 = 3 CO2 + 4 H2O

Propane gas plus oxygen gas produces carbon dioxide and water. The balanced chemical equation is as follows: C3H8 + 5O2 → 3CO2 + 4H2O

Propane is a member of the alkane group with the chemical formula; C3H8 while oxygen gas has the chemical formula; O2.

Propane gas (C3H8) and oxygen gas (O2) combines to produce carbon dioxide (CO2) and water (H2O).

The chemical equation is as follows:

C3H8 + O2 → CO2 + H2O

However, the above equation is not balanced. To balance it, we make use of coefficients to make the number of atoms of each element equal.

The balanced equation is as follows:

C3H8 + 5O2 → 3CO2 + 4H2O
