Answer 1

Wavelength  = 6.25 x 10⁻¹⁰ m

Energy=3.1805 x 10⁻¹⁶ J

Further explanation

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3.10⁸

λ = wavelength

Frequency : 4.8 x 10¹⁷ /s

the wavelength  :

[tex]\tt \lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3.10^8}{4.8.10^{17}}=6.25\times 10^{-10}~m[/tex]

Energy :

[tex]\tt E=6.626.10^{-34}\times 4.8\times 10^{17}=3.1805\times 10^{-16}~J[/tex]

Decreasing the temperature causes the molecules in this reaction to become less excited or reactive, thus causing the reaction to slow down

Choose the electron configurations which are possible for an unexcited atom. Example 1 – 1s22s22p4 Example 2 – 1s22s22p63s23p33d1 Example 3 – 1s22s22p83s1 Example 4 – 1s22s22p63s1

Answers

Answer:

Examples 1, 3 and 4

Explanation:

An unexcited atom is an atom in the ground state i.e the atom has it's valence electrons in it's lowest energy level possible. This actually implies the normal electronic configuration of the atom. Thus, examples 1, 3 and 4 have the actual electronic configuration with there valence electrons in the lowest possible energy level.

Example 1: 1S² 2S² 2P⁴

Example 3: 1S² 2S² 2P⁶ 3S¹ (There seem to be a mistake in the question provided, P energy level can only 6 electrons not 8)

Example 4: 1S² 2S² 2P⁶ 3S¹

NOTE: If you take a look at example 2, it will be deduced that the 3P energy level has only 3 valence electrons and the last valence electron jumped to 3d energy level; making that atom appear to be in it's excited state.

Is it OK for people to post fake vacation pics and other fake info on social media? Why or why not? Use facts and details from the Article to back up your answer.

Answers

Answer:

No, It is not okay to pretend on social media.

Explanation:

No, it is not okay for people to post fake vacation pics and other fake info on social media. This is very wrong, as -

This 'all time look good, feel good, have a happening life' approach of social media - implies showing only the positive side & not negative side of people's life. However, in real life is not a bed of roses. Faking things out implies that pretending to be cool has become more important than sharing deep meaningful relationships, & highlights  superficial desire of false popularity. It is also harmful to people being communicated this fake image, as they might indulge into any social involvement, on the basis of unreal image of the concerned person.

Imagine you are a scientist who has just discovered a new element. The element has an atomic number of 113, and it has three elections in the outer energy level of each atom.
Which element would have properties most similar to the new element?
Group of answer choices

A.boron
B.carbon
C.hydrogen
D.beryllium

What would you name this new element?

Answers

Answer:

3 valence electrons

The element with the atomic number 113 would fall in the 13th column of the periodic table Group IIIA. This group has an electron configuration that would end as p1 , meaning there would be 3 valence electrons. The valence electrons are the electrons found in the highest energy level in the s and p orbital.

Explanation:

Nihonium has to be the #113 element of the periodic table

A. is the correct answer because Boron has 3 electrons too,

All elements in Group 13 have three electrons in their outermost energy level. The two most popular elements in this group are Boron and Aluminum.

Boron element would have properties most similar to the new element. Therefore, option (A) is correct.

Why do the elements of same group have similar chemical behavior?

The chemical properties of elements depend on the number of valence electrons in their valence shell. Elements in the same group in the modern periodic table have the same number of valence electrons. Therefore, chemical elements situated in same group of the modern periodic table have similar chemical behavior.

The chemical elements having an identical outer electronic configuration in their atoms are placed in the same group of the periodic table. These valence electrons of an element are responsible chemical behavior and reactivities of the elements.

Therefore, both Boron and a new element with atomic number 113  have three electrons in their valence shells. So they belong to the same group and will have similar chemical properties.

Santiago's car has an overall average speed of 25 cm/s. If he could increase his car's overall average speed by 10%, what would his car's new overall average speed be?

Answers

Given:

The overall average speed = 25 cm/s.

The overall average speed increased by 10%.

To find:

The new overall average speed.

Solution:

We have,

Overall average speed = 25 cm/s.

The overall average speed increased by 10%. So, the new average speed is

New overall average speed = Initial average speed + 10% of initial  overall average speed

[tex]\text{New overall average speed}=25+\dfrac{10}{100}\times 25[/tex]

[tex]\text{New overall average speed}=25+2.5[/tex]

[tex]\text{New overall average speed}=27.5[/tex]

Therefore, the new overall average speed is 27.5 cm/s.

Which of the following contains the most atoms?

39.098 gk
21.62 g B
9.0122 g Be

Answers

Explanation:

9.0122 g be Maybe, sorry i don't think so

In the above , the sample of B 21.62 g of boron contains the most atoms because it has approximately 2 moles, while the other samples have only 1 mole each.

What is atoms

The molar mass of each element can be found on the periodic table.

The molar mass of Mg (magnesium) is about 24.305 g/mol.The molar mass of K (potassium) is about 39.098 g/mol.The molar mass of B (boron) is approximately 10.81 g/mol.The molar mass of Be (beryllium) is about  9.0122 g/mol.

To calculate the number of moles in each sample, we divide the mass of each sample by its respective molar mass:

For Mg: Number of moles = 24.305 g / 24.305 g/mol = 1 moleFor K: Number of moles = 39.098 g / 39.098 g/mol = 1 moleFor B: Number of moles = 21.62 g / 10.81 g/mol ≈ 2 molesFor Be: Number of moles = 9.0122 g / 9.0122 g/mol = 1 mole

Therefore, the sample with 21.62 g of boron (B) contains the most atom
