Answer:

Are transferred completely from the valence shell of an element to the other

Explanation:

Basically, to form a chemical bond, you either transfer or you share. When you share, it is a case of covalent bonding which can be in several other forms. When there is a transfer, it is a case of ionic bonding.

The basic explanation for this is that while some atoms are electronically sufficient, some are electronically deficient. This means while some atoms are having an excess number of electrons, then some are having less number of electrons.

To satisfy both parties, there must be a transfer if electrons between the two parties. While the one with the excess numbers serves as the donor, the one with insufficient number of electrons serve as the acceptor

Do all states of matter have thermal energy?

Y_Kistochka [10]

Explanation:

It is the motion of particles that creates a form of energy called heat (or thermal) energy that is present in all matter. Tiny particles in solids, liquids and gases are always in motion. It is the motion of particles that creates a form of energy called thermal (heat) energy that is present in all matter.

The heat of vaporization for water is 40. 7 kJ/mol. How much heat energy must 150. 0 g of water absorb to boil away completely?

netineya [11]

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

The heat of vaporization has been the amount of heat required to vaporize 1 gram of liquid.

The heat required for the vaporization has been given as:

$Q=m\Delta H_{vap}$

<h3 /><h3>Computation for the Heat of vaporization</h3>

The heat of vaporization of water has been given as, $\Delta H_{vap}=40.7\;\rm kJ/mol$

The mass of water sample has been, $m=150\;\rm g$

Substituting the values for the heat energy absorbed, Q:

$Q=150\;\times\;40.7\;\rm kJ\\
\textit Q=6,105\;kJ$

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

At 45 ∘C, Kc = 0.619 for the reaction N2O4(g)⇌2NO2(g). If 48.2 g of N2O4 is introduced into an empty 2.08 L container, what are

vodka [1.7K]

Answer:

P N₂O₄ = 3,05 atm

P NO₂ = 7,04 atm

Explanation:

48,2g of N₂O₄ are:

48,2g ₓ (1mol / 92,011g) = 0,524mol of N₂O₄ / 2,08L = 0,252M

Based on the reaction

N₂O₄(g) ⇌ 2NO₂(g) Kc = 0,619 = [NO₂]² / [N₂O₄] (1)

Concentrations in equilibrium are:

[N₂O₄] = 0,252M - X

[NO₂] = 2X

Replacing in (1):

0,619 = [2X]² / [0,252-X]

0,156 - 0,619X - 4X² = 0

Solving for X:

X = -0,289 → False answer, there is no negative concentrations

X = 0,135

Replacing:

[N₂O₄] = 0,252M - 0,135

[N₂O₄] = 0,117M

[NO₂] = 2X

[NO₂] = 2×0,135 = 0,270M

using:

P = M×R×T

Where P is pressure, M is molarity, R is gas constant (0,082atmL/molK) and T is temperature (45 + 273,15 = 318,15K). Pressure of N₂O₄ and NO₂ are:

P N₂O₄ = 0,117M×0,082atmL/molK×318,15K = 3,05atm

P NO₂ = 0,270M×0,082atmL/molK×318,15K = 7,04atm

I hope it helps!

Consider the equation below.

Ksenya-84 [330]

Answer:

1 : 1

Explanation:

We know that the equation is balanced because the number of zinc, hydrogen, sulfur and oxygen atoms are the same in both sides of the equation.

Zn + H2SO4 → ZnSO4 + H2

We can see that there is one molecule for Zn and also one molecule for ZnSO4 (we know this because there are no numbers before the formulas, so the 1 is implied)

That is why the mole ratio of zinc to zinc sulfate is 1 : 1
