Answer:

Hydrogen Chloride is 74.64 grams.

Explanation:

Using the given information, we can find the amount of grams of hydrogen chloride that take place in the reaction.

Due to the Law of Conservation of Mass, the mass of the system must remain constant. To find the value of x, make the equation below.

[tex]24.30 + x=2.04 + 96.90[/tex]

The left side represent the reactant side of the chemical reaction and the right side represents the product side.

[tex]2.04 + 96.90= 98.94[/tex]

[tex]24.30+x=98.94[/tex]

[tex]24.30 - 24.30 + x= 98.94 - 24.30[/tex]

[tex]x=74.64[/tex]

Answer:

%Li-6 = 5.996% & %Li-7 = 94.004%

Explanation:

let X₁ = Li-6 & X₂ = Li-7 where Xₙ = mole fraction

X₁ + X₂ = 1 => X₁ = 1 - X₂

6·X₁ + 7·X₂ = 6.94004

=> 6(1 - X₂) + 7·X₂ = 6.94004

=> 6 - 6·X₂ + 7·X₂ = 6.94004

=> 6 + X₂ = 6.94004

X₂ = 6.94004 - 6 = 0.94004 => %X₂ = %Li-7 = 94.004%

X₁ = 1.00000 - 0.94004 = 0.05996 => %X₁ = %Li-6 = 5.996%

Answer:

verical rays

Explanation:

The rays result in shorter days are the vertical rays.

Vertical rays are another name for direct rays. Rays that are straight overhead are referred to as vertical. Because the Earth is spherical, not all the Sun's rays hit it directly or vertically.

Vertical rays lose less heat because they cover a shorter distance. Slanted rays cover more ground and dissipate more heat. Sun's vertical rays fall between the Tropics of Cancer and Capricorn, along its migratory belt.

The length of a day is determined by the Earth's rotation around its axis, which has been accelerating during the past several decades. Our days have been becoming shorter due to this tendency.

Thus, vertical rays are responsible for shorter days.

Answer:

liquid no not a solid

Explanation:

When you put the substance in a 25 mL beaker. then the state of matter is solid, appearance and texture are powdered and crystalline structure is not solid(powder).

The term "crystalline structure" refers to the arrangement of atoms, ions, or molecules in a crystalline solid. A crystalline solid is a type of material where the constituent particles are arranged in a regular, repeating pattern. This regular arrangement results in a characteristic geometric shape for the crystals. Examples of crystalline solids include salt, sugar, and diamond.

On the other hand, the term "state of matter" refers to the physical form in which matter exists. There are three primary states of matter: solid, liquid, and gas.

Solids have a definite shape and volume and their constituent particles are held tightly together by strong intermolecular forces.

Liquids have a definite volume but no definite shape, and their constituent particles are held together by weaker intermolecular forces.

Gases have no definite shape or volume, and their constituent particles are far apart and move freely.

Other states of matter, such as plasma and Bose-Einstein condensate, also exist but they are less common in everyday life.

Therefore, the state of matter: is solid, its appearance and texture: are powdered, and the crystalline structure: is not solid.

Answer:

The ovary contains ovules

Explanation:

Since the addition of the H2O in the last step of hydroboration is anti-Markovnikov, the starting material is 1-pentyne.

The addition of H2 to C5H8 yields an alkene when a Lindlar catalyst is used. Recall that the Lindlar catalysts poisons the process so that the addition do not go on to produce an alkane.

When hydroboration is carried out on the alkene, we are told that a primary alcohol was obtained. We must note that in the last step of hydroboration, water is added in an anti- Markovnikov manner to yield the primary alcohol. Hence, the starting material must be 1-pentyne as shown in the image attached.

This problem is asking for the reason behind the nonexistence of elementary substances with ionic bonds. First of all, it is necessary to bear to mind that the definition of the type of bond in a compound depends on the difference electronegativity that is present between two of the atoms composing it.

For instance, in binary salts, such as KCl, NaCl, KBr and so on, we are able to know these are all ionic because they are composed by a metal and a nonmetal, which have the smallest and largest electronegativities, so that the difference electronegativity is large enough to produce an ionic bond.

In contrast, elementary susbtances, such as liquid bromine (Br2) and gases such as H2, N2, Cl2, F2 and O2, since they are all nonmetals and the same type, the electronegativity difference will be 0 and therefore, they will not be ionic but covalent.

Explanation:

Answer:

R, the gas law constant, is a constant,

Solubility of gas is inversely proportional to temperature.

Solubility of gas ∝ 1/Temperature

That means as temperature increases the solubility gas goes on decreasing and vice versa.

But R is inversely proportional to temperature .

So Solubility ∝ R. (1/T ∝ R)

That means solubility of gas goes on increasing as R increases.

Step 2: Result

Result:

So from above conclusion the solubility of Oxygen in water increases that result into increasing R value.

Valence electrons are negatively charged particles located in the outermost shell of atoms that can be transferred or shared with other atoms. Valence electrons are important in chemistry because the number of valence electrons in a particular atom can be used to determine how the atom will react chemically with other atoms.

Answer:

Pb[lead] [Xe]4f^145d^106s^26p^2

U[uranium] 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4e^14 5d^10 6p^6

7s^2 5f^4

This notation can be written in core notation or noble gas notation by replacing the

1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4e^14 5d^10 6p^6

7s^2 5f^4

with the noble gas [Rn].

N[nitrogen] The full electron configuration for nitrogen is 1s^2 2s^2 2p^3.

Ti[titanium] Ti2+:[Ar]3d^2

1s^2 2s^2 2p^6 3s^2 3p^5 = 17 electrons

(1) electron gain will result to a

negative charge (−), and

(2) electron loss will result to a positive charge (+),

1s^2 2s^2 2p^6 3s^2 3p^6 = 18 electrons

Hg[mercury] You should then find its atomic number is 80. It has a Xe core, so in shorthand notation, you can include [Xe]instead of

1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 5s^2 5p^6,

for 54 electrons. For the 6th row of the periodic table, we introduce the 4f orbitals, and proceed to atoms having occupied 5d orbitals. We, as usual, have the ns orbitals, and n=? for the 6th period?

Mercury has a regular electron configuration. It becomes:
