In what main way is fission different from radioactive decay? Are all fission events in a chain reaction identical? Explain.

1 answer:

4 0

Radioactive decay is a spontaneous process in which unstable nuclei emit radioactive particles and energy. Fission occurs as the result of high-energy bombardment of nuclei that cause them to break into smaller nuclei, radioactive particles, and energy. All fission events are not the same. The nuclei split in a number of ways to produce several different products.

<h3>What is Radioactive?</h3>

The process through which an unstable atomic nucleus loses energy through radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A substance that has unstable nuclei is regarded as radioactive. Alpha decay, beta decay, and gamma decay are three of the most frequent kinds of decay, and they all entail the emission of one or more particles.

Beta decay is a result of the weak force, while the nuclear force and electromagnetism are in charge of the other two mechanisms. The capture of an inner electron from one of the electron shells by an unstable nucleus is the fourth prevalent form of decay. A series of electrons drop as a result of that electron being lost from the shell.

Which of the following bases is the STRONGEST? The base is followed by its Kb.A. C6H5NH2, 4.0 × 10-10 B. NH3, 1.76 × 10-5 C. CH3

Kamila [148]

Answer:

(D) (CH3CH2)2NH

Explanation:

In order to decide which base is strongest we need to calculate its PKb

PKb = -log [Kb]

A large Kb value and small PKb value gives the strongest base

Compound Kb PKb

(A) C6H5NH2 - 4 x 10^-10 9.349

(B) NH3 1.76x 10^-5 4.754

(D) (CH3CH2)2NH 8.6x 10^-4 3.066

(E) C5H5N 1.7x10^-9 8.77

Clearly (CH3CH2)2NH is the strongest base.

Hydrogen is unique among the elements because __________. 1. It has only one valence electron. 2. It is the only element that ca

Talja [164]

Answer:

3,4

Explanation:

Hydrogen has no other electron hence there is no screening of the valence electron by inner electrons. It is the lightest known element with a relative molecular mass of 2. Screening effect refers to the fact that inner or core electrons prevent the outermost electron from feeling the attractive force of the nucleus.

Given the following equation: 2 K + Cl2 ---> 2 KCl

Ksivusya [100]

Answer:

2 moles of KCl will be produced

Explanation:

Given parameters:

Number of moles of K = 2 moles

Unknown:

Number of moles of KCl produced = ?

Solution:

To solve this problem;

Obtain a balanced chemical equation:

2K + Cl₂ → 2KCl ;

Since K is the limiting reactant, its amount will determine the extent of this reaction.

From the balanced equation;

2 moles of K will produce 2 moles of KCl

Given that 2 moles of K reacted, 2 moles of KCl will be produced

Which formula contains two non- metals?<br><br>BaO<br>NaBr<br>KI<br>Si O2

Yakvenalex [24]

SiO2 is the only possible choice because the other formulas contain metals. how do we know this? because the other formulas contain elements located on the left of the “staircase” on the periodic table that separates metals from non-metals.
