Pls help if you can, Thx! Describe ozone creation and loss in the ozone layer. Does one occur more than the other?

Answers

They Ozone was created millions of years ago from a natural process frozen in ice during the ice age, the gases that make up the ozone layer were formed naturally from a reaction of ultraviolet radiation and molecular oxygen which was frozen in the ice during the time of the ice age was released over years as the ice melted. However over hundreds of years of mechanical evolution and other man based forms of carbon production the ozone layer has decreased much faster than it has been repaired, meaning loss of the ozone layer occurs more often

What is an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Explanation:

From the question,

Applying boyles law

PV = P'V'................ Equation 1

Where P = initial pressure, V = Initial Volume, P' = Final pressure, V' = Final Volume.

make V' The subject of the equation

V' = PV/P'............. Equation 2

Given: P = 2 kpa, V = 60 liters, P' = 1 kpa

Substitute these values into equation 2

V' = (2×60)/1

V' = 120 liters

Hence the right option is A. 120 liters

- The pit of an aqueous solution of NaOH is 12.9. What is the molarity of the solution?

Answers

Answer: The molarity of solution is 0.08 M

Explanation:

pH is the negative logarithm of hydrogen ion concentration. It tells abpout the acidity or basicity of a solution.

[tex]pH=-log[H^+][/tex]

also pH+pOH=14

given : pH of NaOH = 12.9

Thus pOH = (14-12.9) = 1.1

Thus [tex][OH^-]=10^{-1.1}=0.08M[/tex]

As [tex]NaOH\rightarrow Na^++OH^-[/tex]

As 1 mole of [tex]OH^-[/tex] is produced by = 1 mole of NaOH

Thus 0.08 moles of [tex]OH^-[/tex] are produced by = [tex]\frac{1}{1}\times 0.08=0.08[/tex] moles of NaOH

The molarity of solution is 0.08 M

Your friend works in a bookstore where lab books for science are assembled. Each lab book uses 2 covers, 50 sheets of lined paper, 25 sheets of graph paper and 3 staples. Her inventory includes 150 covers, 7500 sheets of lined paper and 3000 sheets of graph paper and 250 staples. What is the “limiting reactant?” How many complete lab books can be made? How much of each of the other reactants remain in excess?

Answers

Answer:

The limiting reactant is the covers.

We are left with 3750 sheets of lined paper, 1125 sheets of graph paper and 25 staples.

Explanation:

the reaction is:

B - book

C - cover

Sl = sheet of lined paper

Sg - sheet of graph paper

St - staple

1B = 2C + 50Sl + 25Sg + 3St

We have covers for 150/2 = 75 books

We have lined paper for 7500/50 = 150 books

We have graph paper for 3000/25 = 120books

We have Staples for 250/3 = 83.(3) books, so for 83 books as we cannot make 1/3 of a book.

Because we only have covers for 75 books, covers are the limiting reactant.

After making 75 books we are left with:

0 covers

7500 - 75*50 = 3750 sheets of lined paper

3000 - 75*25 = 1125 sheets of graph paper

250 - 75*3 = 25 staples

The limiting reactant should be the covers.

We are left with 3750 sheets of lined paper, 1125 sheets of graph paper, and 25 staples.

Calculation of the limiting reaction:

The reaction should be like:

B - book

C - cover

Sl = sheet of lined paper

Sg - sheet of graph paper

St - staple

Now the equation should be

1B = 2C + 50Sl + 25Sg + 3St

We have covers for 150/2 = 75 books

We have lined paper for 7500/50 = 150 books

We have graph paper for 3000/25 = 120books

We have Staples for 250/3 = 83.(3) books, so for 83 books as we cannot make 1/3 of a book.

Now the left should be

7500 - 75*50 = 3750 sheets of lined paper

3000 - 75*25 = 1125 sheets of graph paper

250 - 75*3 = 25 staples

Two experiments are performed on an object to determine how much the object resists a change in its state of motion while at rest and while in motion. In the first experiment, the object is pushed with a constant known force along a horizontal surface. There is negligible friction between the surface and the object. A motion sensor is used to measure the speed of the object as it is pushed. In a second experiment, the object is tied to a string and pulled upward with a constant known force, and a motion sensor is used to measure the speed of the object as it is pulled upward.
