Answer:

I would say who invented the ratio

Explanation:

Well you dont need to use the scientific method to know WHO discovered it, you use it to determine HOW

The wavelength-λ = 6.12 x 10⁻⁷ m

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  m/s

λ = wavelength

The wavelength of radiation with a frequency of 4.9 ×10¹⁴/s :

[tex]\tt \lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3.10^8}{4.9\times 10^{14}}\\\\\lambda=6.12\times 10^{-7}~m[/tex]

The difference between the monomer and a polymer should be that monomer should be larger than a polymer.

The monomer represent the molecule type where it has the capability for chemically the bond along with the other molecules with respect to the long chain. While the polymer should represent the chain of the non-specified the no of monomers.

Also, it represent the building blocks of polymers that contain more complex type of molecules

Answer:

solid ,hard, not see through

Explanation:

Answer:

There are many properties out there, so three include bright yellow color, luster shine, and the maleability that determines the durability.

Answer: The statement that is not a determining factor in formation of intrusive igneous rocks is 'None of the above' and Magma cools very fast beneath the Earth's surface.

Explanation:

Rocks are naturally occurring solid materials that are made up of different types of minerals which affects it's texture and colours. The three main types of rocks are:

--> sedimentary rocks,

--> metamorphic rocks and

--> igneous rocks.

Igneous rocks are formed from the crystallization and solidification of hot molten rocks which originates from deep within the earth. Depending on where the molten rock solidifies, the igneous rock is divided into two, namely:

--> intrusive igneous rock and

--> extrusive igneous rock.

The INTRUSIVE IGNEOUS rocks are formed within or deep beneath the earth surface when the hot magma SLOWLY cools over millions of years until it solidifies. The slow cooling allows large crystals to grow.

Therefore the statements (None of the above and Magma cools very fast beneath the Earth's surface) are not a determining factor.

The equation can be balanced using suitable integers multiplied either side and can be written as follows:

[tex]\rm Ca_{3} (PO_{4})_{2} + 4 H_{3}PO_{4} \rightarrow 3 Ca (H_{2}PO_{4})_{2}[/tex]

Thus the coefficient of H₃PO₄ is 4.

A balanced chemical equation of a reaction represents all the reactants and products in the perfect stoichiometric ratios where, the number of each element have to be equal in both sides.

The given reaction is an example of combination reaction. The equation can be balanced by equating the number of calcium in the product side by multiplying with 3 and then making the phosphate group also balanced by multiplying by 4 with  H₃PO₄.

Thus, the balanced chemical equation written above contains 3 calcium on both side and equal number of phosphate group (6) as well as hydrogens on both side where, the coefficient of  H₃PO₄ is 4

Answer:

WPC medium range forecasting

Explanation:

Answer:

Explanation:

While trying to write the chemical formula for a compound (a neutral molecule), one must identify and exchange the charge of the cation with that of the anion to become the subscript of one other. For example

Aluminium oxide has Aluminium (Al) and oxygen (O); since Al has a charge of 3+ (the cation) and O has a charge of 2- (the anion), the compound would have it's charges as Al³⁺O²⁻ and when the charges are exchanged to there subscripts, it would form Al₂O₃; thus there would be two cations of aluminium for every three anions of oxygen in order to have a neutral molecule.

This same explanation can be given to Aluminium sulfite. Aluminium sulfite has Aluminium (Al) and sulfite (SO₃). Al has a charge of 3+ (cation) while sulfite has a charge of 2- (anion), with the compound having it's charges as Al³⁺(SO₃)²⁻ and when the charges are exchanged to there subscripts, it would form Al₂(SO₃)₃ and would thus have 2 cations of aluminium (Al³⁺) for every 3 anions of sulfite (SO₃³⁻) in order to have a neutral molecule.

The correct Lewis dot structure for [tex]BeH_2[/tex] is Be : H : H

The Lewis dot structure shows the valence electrons as dots. The valence electrons of beryllium are shown as 2 dots on the left side of the atom.

The central atom, beryllium, has 2 valence electrons where each hydrogen atom has 1 valence electron. To form a stable molecule, beryllium shares its 2 valence electrons with the 2 hydrogen atoms, each of which shares its 1 valence electron with beryllium which gives each atom a full outer shell of electrons.
