Match the following family of elements to its group.

Match The Following Family Of Elements To Its Group.

Answers

Answer 1

Explanation:

To solve this problem, we simply use the periodic table of elements which groups elements based on their atomic numbers.

The atomic number of an element is the number of protons it contains. The protons are the positively charged particles within an atom.

The vertical arrangement of elements on the periodic table is the group. The horizontal arrangement of elements is the period.

Now;

Noble gases  belongs to group 18

Alkali earth metals belongs to group 2

Halogens belongs to group  17

Alkali metals belongs to group 1

Transition metals belongs to group 3-12

How does the ionosphere help radio transmission?

Answers

Due to the ability of ionized atmospheric gases to refract high frequency (HF, or shortwave) radio waves, the ionosphere can reflect radio waves directed into the sky back toward the Earth. Radio waves directed at an angle into the sky can return to Earth beyond the horizon.

help me find out how to get the volume !!! pleaseeee

Answers

The volume using the cylinder formula  : V=πr²h

Further explanation

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

This experiment is an illustration of Charles's law, to determine the relationship between temperature and gas volume

If a certain amount of gas is heated, the volume will increase

So in this experiment, the temperature was changed as an independent variable and tube volume as a fixed variable

Because the tube is cylindrical, to find the volume using the cylinder formula

[tex]\tt V=\pi.r^2.h[/tex]

Meanwhile, to find the radius, you can use a caliper to measure the diameter of the tube and the result will be divided by 2

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The balanced chemical equation is:

[tex]3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3[/tex]

Answer:

10. The wavelength of the color red is 650 × 10⁻⁹ m

11. The frequency of the color red is approximately 4.6122 × 10¹⁴ Hertz

12. The corresponding energy  is approximately 3.058 × 10⁻¹⁹ J

Explanation:

10. Given that the wavelength, λ, of the color red is 650 nm, and one nanometer, nm = 10⁻⁹ m, we have;

The wavelength of the color red = 650 × 10⁻⁹ m

11. The frequency, v, of the color red is obtained from the relation, v = c/λ

Where;

c = The speed of light = 299,792,458 m/s

∴ v = 299,792,458/(650 × 10⁻⁹) ≈ 4.6122 × 10¹⁴ Hertz

12. Given that energy emitted by light, E = h × v, where E = 6.63 × 10⁻³⁴ J/s, we have;

E = 6.63 × 10⁻³⁴ J·s × 4.6122 × 10¹⁴ Hz ≈ 3.058 × 10⁻¹⁹ J

Therefore,  the corresponding energy, E ≈ 3.058 × 10⁻¹⁹ J.

how many atoms are there in 1g of argon the Avogadro constant is 6.02 x 10^23 per mole relative atomic mass (Ar): AR=40

Answers

Answer:

ow many atoms are there in 1g of argon the Avogadro constant is 6.02 x 10^23 per mole relative atomic mass (Ar): AR=40Explanation:

The number of atoms of argon in 1g of argon is 1.5 × 10²² atoms

From the question,

We are to determine the number of atoms present in 1g of argon.

To determine this,

First we will calculate the number of moles of the 1g of argon

From the formula

[tex]Number\ of\ moles = \frac{Mass}{Atomic\ mass}[/tex]

From the given information

Mass of Argon = 1g

Atomic mass of Argon = 40g/mol

∴ Number of moles of Argon = [tex]\frac{1}{40}[/tex]

Number of mole of Argon = 0.025 mole

Now,

For the number of atoms of argon present

Using the formula

Number of atoms = Number of moles × Avogadro's constant

∴ Number of atoms of argon present = 0.025 × 6.022×10²³

Number of atoms of argon present = 1.5055 × 10²² atoms

Number of atoms of argon present ≅ 1.5 × 10²² atoms

Hence, the number of atoms of argon in 1g of argon is 1.5 × 10²² atoms

why is the symbol [Ar] used in the electron configuration of potassium, and what does it represent?

Answers

Answer:

To denote a stable inner configuration and it represents argon

Explanation:

The symbol [Ar] used in the electron configuration of potassium represents the inner electronic configuration of the element.

This argon atom is stable octet with completely filled shells. Most noble gases are used to write the electronic configuration of other atoms. The inner atomic orbitals of elements are similar to those of nearby noble gases.

Ar is Argon with a configuration of 1s² 2s² 2p⁶ 3s² 3p⁶So, this configuration is stable and it the inner configuration of potassium excluding the outermost orbitals.

Calculate the specific heat of glass from the following data. The temperature of a piece of glass with a mass of 65 g increases by 26°C when it absorbs 840 J of heat energy.

Answers

Answer:497J/kg/K

Explanation:

Use the equation: Q=mS◇T

According to specific heat capacity, the specific heat of glass is 0.4970 J/gK.

What is specific heat capacity?

Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.

It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.

It is given by the formula ,

Q=mcΔT

Substituting values in above equation, c=Q/mΔT, C=840/65×26=0.4970 J/gK.

Thus, the specific heat of glass is 0.4970 J/gK.
