Why are electron filling orders not the same between the first and the last two elements of group 6B?​

Answers

Answer:

This primarily has to do with the balance of energy between the orbitals. The aufbau principle states that the order of energy regarding electrons in the orbitals from lowest to highest is so the electron in the atom will minimalize it's energy. Periods on the periodic table are based on the energy level while the groups have the same amount of valence electrons. The outer orbitals are refered to as shells. The elements are particularly arranged depending on their atomic and molecular orbitals. Valence electrons most determine the chemical properties of an element. The atomic number is based on the number of protons.

What is the stable end product of the decay of uranium 238

Answers

Lead

Explanation:

by emission of alpha particles

The end product of the decay of uranium 238 is Pb-206.

Heavy elements are generally grouped into four decay series which are; Thorium series, Uranium series and actinium series and Neptunium series.

These heavy elements decay via a series of α and β emissions until a stable nucleus is finally achieved. All these decay series usually terminate in a lead nucleus.

Uranium 238 belongs to the uranium decay series and terminates at Pb-206.

Answers

Answer:

The dog ate the bone hiding under the shady tree.

Explanation:

The best observation is that the dog ate the bone hiding under the shady tree. This is because it provides the most graphic details about the position and activities of the dog.

With this choice, we can properly picture the dog and the relationship it has with the tree. The more information we know about a subject of investigation, the better an observation it affords. Such a well informed observation will make analysis much better.

Answers

Answer:

When two substances that are of different temperatures are brought together and there is heat transfer such that the substances come to thermal equilibrium, the effect on the particle motion are as follows

1) The particle motion of the hotter body reduces, because its temperature reduces

2) The particle motion of the colder body increases, because its temperature increases

3) For gases, the volume and or pressure reduces for the hotter body, and if the temperature of the gas falls below the boiling point temperature, the gas will change into liquid

For the colder gas, only the volume and or pressure increases and the temperature rises

4) For liquids, if the temperature of the hotter liquid falls below the melting point, the hotter liquid will become a frozen solid

For the the colder liquid, if the temperature is raised above the boiling point, the liquid changes into gas and the temperature does not rise above the boiling point temperature, until all the cold liquid has evaporated

5) For solids, the vibration of the particles of the hotter substance reduces and the solid becomes more brittle

For the colder body, the rise in temperature causes an increase in vibration of the particles, and if the temperature rises above the melting point, the colder solid will begin to melt

A solvent is a chemical that dissolves a solute to produce a uniform solution. A solute is a substance that dissolves in a solvent, resulting in a homogeneous mixture. The solute is sucrose, and the solvent is ethanol.

What is meant by solution ?A solution is a well-mixed solution in a solvent of one or more dissolved solutes. A solute is a substance that dissolves another substance, creating a continuous medium. A solute is a substance that dissolves in a solvent, resulting in a homogeneous mixture.A solution is formed when one substance dissolves or degrades into another. A solute is any substance that dissolves to form a solution. A solvent is a chemical that is used to disperse a solute. The solute in a sugar-water solution is sugar, and the solvent is water. A solution is a homogeneous mixture of two or more particles with diameters less than one Nano meter.

A cart has a mass of 35kg and a speed of 1.2m/s. What is its kinetic energy

Answers

Answer:

The answer is 25.2 J

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question we have

[tex]KE = \frac{1}{2} \times 35 \times {1.2}^{2} \\ = 17.5 \times 1.44 [/tex]

We have the final answer as

25.2 J

Hope this helps you

Answer:

25.2 J

Explanation:

Using the kinetic energy formula:

KE = [tex]\frac{1}{2}[/tex]m v²

Plug in the given values:

KE = [tex]\frac{1}{2}[/tex] (35 kg) · (1.2 m/s)²

KE = [tex]\frac{1}{2}[/tex] (35) · 1.44

KE = 17.5 · 1.44

KE = 25.2 J

There is a kinetic energy of 25.2 Joules.

Ribosomes are cell structures that make

Answers

Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains.

Ribosomes are cell structures that make protein. They are the primary site of the synthesis of protein. They are made up of protein and RNA.

What are ribosomes?

Ribosomes are cell organelles scattered in the cytoplasm of the cell. They are tiny and round vesicles. They are present in both prokaryotic and eukaryotic cells. Furthermore, they are present freely in the cytoplasm. Ribosomes are also present near the endoplasmic reticulum.

Ribosomes are made up of RNA and protein, and they synthesize the protein in the cell. Ribosomes read the mRNA and by these codes of mRNA, it constitutes amino acids, that grow into a long chain of the protein.

Thus, ribosomes are the parts of cells that produce protein. They serve as the central location for protein production. They are composed of RNA and protein.
