Answer:

HBr is the strongest and its bond is what which makes it the strongest acid.

Explanation:

This acid is dangerous and highly poisonous than other acids. It can disunite instantly. And later then it forms the suspension.

Li_{2}OLi

2

O and LiBr is not merely an acid and henceH_{2}SH

2

S and HBr are the acids, amongst which HBr forms the strong acid component.

The strongest nature is due to the formation of hydronium ions.

The Hydrogen sulphide acid does not release hydronium ions on suspension.

Answer:

HBr is the strongest and its bond is what which makes it the strongest acid.

Answer:

4.99 x 10⁻⁷ meters or 499 nanometers

Explanation:

Use the formula:

λ = c/ν, where λ = wavelength, c = the speed of light (it's constant, 2.998 x 10⁸ m/s), and ν = frequency

λ = (2.998 x 10⁸ m/s)/(6.01 x 10¹⁴ 1/s)

λ = 4.98835 x 10⁻⁷

Round to nearest hundreth and you get 4.99 x 10⁻⁷ meters, or 499 nanometers.

Answer:

Both types of waves transfer energy

Explanation:

I think that's right

Electromagnetic waves and sound waves  both types of waves can transfer energy.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Answer:

C. 2NaOH + H₂SO₄ -> Na₂SO₄ + 2H₂O

Explanation:

Simply count up the elements in the reactants and the products, then compare.

Reactants:

2 Na = 2 Na

2 O + 4 O = 6 O

2 H + 2 H = 4 H

Products:

2 Na = 2 Na

4 O + 2 O = 6 O

2 x H₂ = 4 H

Because the constituent elements in the reactants = products, the law of conservation of mass is preserved. You can check the other 3 options to see that they will not equal each other.

Don't forget to distribute the coefficients to every part of the formula; on the other hand, subscripts only apply to the element they are under. If a coefficient needs to be multiplied to an element with a subscript, use the subscript instead of 1 (1 is when there are no subscripts).

Explanation:

Load=500N

Effort=100N

Now,

We have,

Mechanical advantage= Load / effort

= 500/100

=5

Therefore, mechanical advantage is 5.

The concept of covalent bond was introduced by the scientist G.N Lewis in 1916. The molecular geometry of PF₂Cl₃ is trigonal bipyramidal.

In Lewis structure, dots represent electrons. Such structures are referred to as Lewis dot structures or simply Lewis structures. They provide a picture of bonding in molecules in terms of the shared pairs of electrons and the octet rule.

In PF₂Cl₃, 'P' with 5 electrons generally combines with fluorine and chlorine having seven electrons. So the total number of electrons in PF₂Cl₃ is 40.

1. The number of lone pairs = 0

The number of single bonds = 5

The number of double bonds = 0

2. PF₂Cl₃ obeys octet rule except phosphorous, because of the presence of extra orbital it can able to accommodate more than eight electrons. Hence its valency is found to be expanded and it is hypervalent.

Thus the correct option is C.

Answer:

See explanation

Explanation:

7. As we move down the group more shells are added. The addition of more shells means that the atom becomes larger and the outermost electron is now at greater distance from the nucleus and screening effect becomes very important. This greater screening effect of the inner electron reduces the magnitude of effective nuclear charge on the outermost electron thereby lowering the ionization energy.

8. As we move across the period, the effective nuclear charge increases without a corresponding increase in the number of shells. As a result of this, the outermost electron becomes more tightly bound to the nucleus as the atom becomes smaller and atomic radius decreases causing a rise in the ionization energy from left to right across a period.

9. Actually, the smaller an atom is the greater its electron affinity. The smaller the atom is, the more the outermost shell is drawn closer to the nucleus and this means that the atom is better able to attract electrons to itself.

It is due to the size of atom which varies its force of attraction.

As you move down a group, the atomic radius increases due to addition of more number of shells in an atom.  This increase in atomic radius would result in a lower  ionization energy because the valance electron is farther from the nucleus and held with weak attractive force so less energy is required to remove it.

While on the other hand, as we move from left to right in a periodic table the atomic radius decreases due to addition of more electrons which shrinks the atom and brought the valance shell closer to the nucleus so it becomes harder to remove an electron because the nucleus held these electrons very tightly.

The size of an atom will affect its ability to attract additional electrons because of its force of attraction. Atoms with small radius has more ability to attract electrons due to higher force of attraction as compared to higher atomic radius atoms.

Answer:

Air Temp 77F Dew-point 19F

Explanation:

Quiz

The dew point can be described as the temperature required by the air to be cooled. The driest air will have a higher dew point, therefore, at an air temperature of 66°F and a dew point of 60°F. Therefore, option (C) is correct.

The dew point can be defined as the temperature at which air should be cooled to become saturated with water vapor assuming constant air pressure and water content.

Moisture capacity will decrease below the dew point. Airborne water vapor will condense to form liquid water or dew. Dew develops on the surface and occurs through contact with a cooler surface.

The dew point is called the frost point when the temperature is below the freezing point because frost is produced by deposition rather than a condensation of water.

The humidity also impacts the dew point. The dew point increases when there is higher moisture in the atmosphere.  Therefore, the higher dew point refers to less humid air or drier.
