Answer:

beneath the surface of Earth

Explanation:

Diamonds are made up of carbon that has been placed under extreme heat and pressure conditions.

These conditions of high pressure and temperature can only be found within the subsurface. As you go deeper to the mantle, the geothermal gradient rises significantly.

Also, the overburden pressure will also be high.

These processes can also occur on other planets and some can be associated to the earth times when the earth was being formed.

The condition at which diamond forms confers some of the distinct natural properties that typifies it.

Answer:

A molecular formula tells us what atoms and how many of each type of atom are present in a molecule.

Explanation:

If only one atom of a specific type is present, no subscript is used.

For atoms that have two or more present, a subscript is written after the symbol for that atom.

Molecular formulas do not indicate how the atoms are arranged in the molecule.

- Hope this helps! -blazetoxic123

In a molecular formula, the subscripts represent the number of atoms of each element present in a molecule.

The molecular formula gives you the specific combination and quantity of atoms that make up a single molecule of a compound.

For example, consider the molecular formula of water, which is H₂O:

"H" represents hydrogen.

"O" represents oxygen.

The subscript "2" next to "H" indicates that there are two hydrogen atoms in one molecule of water.

The absence of a subscript next to "O" means that there is only one oxygen atom in one molecule of water.

So, the molecular formula H₂O tells us that a water molecule is composed of two hydrogen atoms and one oxygen atom bonded together.

Here are a few more examples to illustrate the importance of subscripts in molecular formulas:

Methane: CH₄ (One carbon atom and four hydrogen atoms)

Carbon dioxide: CO₂ (One carbon atom and two oxygen atoms)

Ethanol: C₂H₅OH (Two carbon atoms, six hydrogen atoms, and one oxygen atom)

The subscripts are crucial in distinguishing between different compounds with the same elements. For instance, carbon monoxide (CO) and carbon dioxide (CO₂) have different molecular structures and properties, even though they both contain carbon and oxygen. The subscripts in the molecular formula help to specify the unique arrangement of atoms within each molecule.

The volume using the cylinder formula  : V=πr²h

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

Answer: double displacement

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]

Thus as ions get exchanged , it is double displacement reaction.

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.

I believe is the npp i kinda forgot how to do these lol

Diagram with npp type shows an atom that is not a form of hydrogen.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

MgO has a highest melting point

C5Br has lowesst

Explanation:

It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. ... Magnesium oxide is made from ions with two charges (Mg 2+ and O 2-) and so has a much higher melting point of 2852°C.
