Why is large scale nuclear fission a rare phenomenon on earth ?

Answers

Answer 1

Answer:

Answer:

The correct answer is option C.

Explanation:

The radioisotopes in the Earth's interior are not in pure form and exhibit various entrenched impurities and are interspersed. Thus, when a neutron is discharged by a decaying atom, its occurrences of hitting another atom of radioisotope in order to continue the chain reaction becomes lower in comparison to the man-made nuclear reactor. In this manner, the radioactive chain reaction in the interior of the Earth is not well-sustained.

Answer 2

Answer:

Answer: C

Explanation:

Atoms that undergo fission aren’t concentrated enough to sustain a chain reaction.

Which method can be used to make a reliable guess that a victim was under 17 years old?A) look for flat-bladed incisors
B) look for presence or absence of wisdom teeth
C) multiply the internal distance in centimeters between the coronoid processes by the external distance in centimeters between the jaw angles(mandibular angles)
D) look for shovel shaped incisors
(It's not C)

Answers

Answer:

B) look for presence or absence of wisdom teeth

Explanation:

The only way to make a reliable guess if a victim was under 17 years old is by looking if he already had the wisdom teeth, this teeth are located in the back of the mouth, and are the third molars that humans develop after the age of 17 or 18 years on average, some could develop them after.

B-Look for the presence or absenceof wisdom teeth

When a substance dissolves, it undergoes a _____.

Answers

The right answer is physical change.

In the general sense, dissolution is the action of dissolving something, that is to say, of decomposing it by the separation of its parts.

In chemistry, dissolution is an intimate mixture of two bodies, at least one of which is liquid.

Eg: the dissolution of sugar in the water, the sugar will pass from the solid and dry state to the dissolved state so there is a physical change. The sugar is going to be surrounded by water molecules and form hydrogen bonds, so it can be a chemical change.

2 types of changes
physical change
chemical change

the easy way to tell the difference is
a physical change is genrally reversable
it changes the look but not the composition
for example, water freezes into ice is physical change

a chemical change is generally not reversable (easily)
ex metal rusting, egg rotting
it changes theh composition itself

when a substance disolves, it actually merges and the molecules move around and sometimes bond
so it's a chemical change

Which of the following statements about subatomic particles best characterizes electrons? A positive charge, light, circling the nucleusB no charge, heavy, found in nucleusC negative charge, light, circling the nucleus D negative charge, heavy, circling the nucleus

Answers

Every electron carries one elementary negative charge. Concerning mass,
it takes roughly 1,840 electrons to make enough mass for 1 proton or 1 neutron.
Electrons don't necessarily have to stay connected to an atom, but when they do,
they circle the nucleus.

So you should select (C): ==> Negative, ==> light, ==> circling the nucleus.

The answer should be (C) negative charge, light and circling the nucleus.

Why? ---- An electron always has negative charge. Its mass is 1/ 1900 times the mass of proton and it circles the nucleus.

A mixture of CH4 and H2O is passed over a nickel catalyst at 1000 K. The emerging gas is collected in a 5.00-L flask and is found to contain 8.62 g of CO, 2.60 g of H2, 43.0 g of CH4, and 48.4 g of H2O.

Answers

The given question is incomplete. But the complete question is this:

A mixture of $CH_(4)$ and $H_2O$ is passed over a nickel catalyst at 1000 K. The emerging gas is collected in a 5.00-L flask and is found to contain 8.62 g of CO, 2.60 g of $H_2$ , 43.0 g of $CH_(4)$ , and 48.4 g of $H_(2)O$ . Assuming that equilibrium has been reached, calculate $K_(p)$ for the reaction.
