Here the nuclear decay of phosphorous to give S-32 is an example of beta-decay. Hence, the emitted particle is an electron. Thus, option b is correct.

What is beta decay ?

The heavy unstable radioactive isotopes undergo nuclear decay by the emission of alpha or beta particle. Thus, there are mostly two types of decays, alpha decay and beta decay.

In alpha decay, the isotope emits a helium nuclei. Hence, mass number decreases by 4 units and atomic number decreases by 2 units. In beta decay, mass number does not change but atomic number increases by 1.

Here, P-32 undergo beta -decay by emitting an electron to form S -32. Hence, atomic number is increased by one. Therefore, the mission product is an electron option b.

how many neutrons of atomic mass is 31 and atomic number is 12

Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

As we know, Number of protons = Atomic Number

So,

Number of protons = 12

And, Atomic mass = Number of protons + Number of Neutrons (N)

therefore ~

31 = 12 + N

N = 31 - 12

N = 19

Number of Neutrons = 19

what is the difference between hypertonic and hypotonic

Answers

Answer: A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane. If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume.

Picture:
Meaning of hypertonic: (1): having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid. (2) of or in a state of abnormally high muscle tone.

What is the mole fraction of hydrogen gas in the products?
a 0.5
b 0.33
C 0.4
d 0.67

Answers

When a gas is collected over water, one must subtract the vapor pressure of water from the total pressure in order to find the pressure of the gas itself. Thus, 1.05 atm - 0.0278 atm = 1.0222 atm = pressure of the O2 gas.

PV = nRT and solve for n to determine moles of O2 collected.
n = PV/RT = (1.0222 atm)(0.5 L)/(0.0821 Latm/Kmol)(296 K) note the use of Kelvin for temperature.
n = 0.02103 moles O2
mass of O2 = 0.02103 moles x 32 g/mole = 0.67 grams (to 2 significant figures)

How many atoms are in 80.45 g of magnesium with explanation

Answers

Answer:

There are 1.9926 * 10 ^24 atoms.

Explanation:

M ( Mg ) = 80.45 g

We can find the molar mass of magnesium in the Periodic table:

M ( Mg ) = 24.31 g / mole

n = 80.45 g : 24.31 g/mole = 3.31 moles

N a ( Avogadro`s constant ) = 6.02 * 10 ^23

N = Na * n = 6.02 * 10 ^24 * 3.31 = 19.926 * 10 ^23

1. You learned that waves in the ocean, sound waves, and light waves all have certain things in common. They all carry energy. The velocity, frequency, and wavelength of each is connected by the same equation. Which type of wave would you most want to learn more about? Why does it interest you? What would you want to find out about it? Write your answers in 2-3 paragraphs. (10 points) Would you like to know more about how waves in the ocean move, how sound travels, or how light works?

2. If you could somehow travel inside an atom and look around, what part of the atom would you want to look at? Why? What would you want to understand better as a result of your "travels"? Write your answers in 2-3 paragraphs. (10 points) Do electrons or the nucleus interest you more? What questions do you still have about how an atom works?

Answers

Answer:

Explanation:

1)  I personally would want to learn more about how the waves in the ocean move. About what causes high tide. What causes low tide. Why some waves are big and some small.  

I know it has something to do with the gravitational pull of the moon. But that is as far as my knowledge extends on the subject. I have always been fascinated with the secrets of the ocean and the secrets of space. To me learning, this is a little of both.

2)  The nature of the interaction between neutrons and protons in the atomic nucleus, which binds the nucleons together, is the biggest wonder in the inside of the atom that I would like to really know. Protons have a positive charge, but neutrons do not. What form of interaction between a charged particle and an uncharged particle is possible? That is what I expect to learn more about as a result of my explorations into the inner workings of the atom.

The inside of the atom is made up of the nucleus and electrons that travel about in orbits. The nucleus is made up of protons and neutrons. Electrons have a negative charge, protons have a positive charge, and neutrons have none. The nucleus is held together by electrostatic interaction between electrons and protons. The majority of the mass of an atom is made up of protons and neutrons.

I'm interested in finding out more about ocean waves travel. regarding the reason for high tide. what brings on a low tide. Although some waves become also large while others are smaller.

What are ocean waves?

Ocean waves seem to be alterations to the ocean's surface. They could be produced by water being moved by the wind, gravity, as well as other forces.

What are waves?

A disturbance that moves from one place to another across a medium has been referred to as a wave. As an illustration of a wave, think of a sinuous wave.

Personally, I'm interested in finding out more about ocean waves travel. regarding the reason for high tide. what brings on a low tide. Although some waves become also large while others are smaller I'm certain that the moon's gravitational force is somehow implicated. Because that is basically the extent of my expertise on the matter. The mysteries of the water and the mysteries of space have always interested me. I'm still learning, so this combines a bit of both.The largest enigma in the interior of the atom something I would really like to understand is the nature of the connection involving neutrons as well as protons in the nucleus of an atom, which holds the nucleons together. Neutrons just don't have a positive electrical charge, whereas protons do. What kind of interactions is conceivable between charged as well as uncharged particles. Through my investigations into the internal workings of the atom, I hope to understand more about it.

What is the molarity of a 75.0 mL solution that contains 0.225 g of
potassium nitrate?

Answers

Answer:

M=0.0297M

Explanation:

we know that molarity equals number of mole of solute over the volume of solution.

M=n/V but n=m/M

n=0.225g÷101g/mol =0.00223mol

M=0.00223mol/0.075l

M=0.0297M

Answer:

0.0297M

Explanation:

We will use the formula M= moles of solute/lites of solution.

First we need to figure out the Moles of the solute, to get this we first need the molar mass of KNO3 (potassimum nitrate).

The Molar Mass of potassimum nitrate is 101.103 g/mol
K - 1 x 39.09
N - 1 x 14.006
O - 3 x 15.999
KNO3 - 101.103 g/mol

Now we get the moles of the solute by doing.
0225g/ 101.103g/mol = 0.00223 mol

Put the answer into the orginal equation to get 0.00223mol / 0.045 L
Which equals to 0.0297M. This is also the correct amount of significant figures.

2. How do pathogens spread?


3. How can we, as humans, prevent transmission of pathogens?


4. List three ways the environment can affect personal health.

Answers

1. Genetic factors are those where the genetic condition of an individual is capable of increasing the probability of developing certain diseases.

Environmental factors include the diversity of environmental stresses such as population density, temperature, food and pollutants that impact human health.

Social factors are related to the interaction of groups through culture, social class and family structure, which also have an effect on population health.

Pathogenic factors, on the other hand, are those transmitted by agents such as viruses, fungi, bacteria and protozoa, which colonize a host by adhering to cells and evading immunity, generating diseases.

2. The transmission of pathogens can occur in several ways, such as contact with bodily fluids from infected people, cross-transmission or through being spread through particles in the air.

3. We can prevent the transmission of pathogens through proper hygiene habits, healthy eating, vaccination against infectious diseases and avoid contact with other people if you have a communicable disease.

4. The environment can affect personal health through climate change, pollution and lack of infrastructure that lead to less access to quality food and basic health conditions.

Health rating: 1

The compound has been less positive towards the health.

Flammability: 4

The compound has been highly flammable.

Reactivity: 0

The compound has been least reactive.
