Answer:

If you're just looking at the Lewis Structure from the perspective of the octet rule, it does appear that the structure is correct. Dinitrogen always has a lone pair of electrons which could conceivably be used for dative bonding as you suggest. So from that perspective there appears to be nothing wrong at all - other than that it doesn't exist in nature in this way.

Explanation:

Answer:

A monoprotic acid has only one equivalence point in a titration curve while a triprotic acid has three equivalence points.

Explanation:

Monoprotic acids, HA, are acids that are able to donate one proton per molecule during the process of ionization or dissociation as shown below:

HA ----> H⁺ + A⁻

A triprotic acid is a polyproprotic acid, that is acids that can donate more than one proton per molecule during ionization. a triprotic acid can donate three protons per molecule during the process of ionization. The dissociation of a triprotic acid is shown below;

H₃A -----> H₂A⁻ + H⁺

H₂A⁻ ----> HA²⁻ + H⁺

HA²⁻ -----> A³⁻ + H⁺

The value Ka, is known as the acid dissociation constant. It is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates

A titration curve is the plot of the pH of the analyte solution versus the volume of the titrant added as the titration progresses.

In a titration curve in which base is added to acid, the pH rises slowly until the equivalent point at which point the pH remains constant before it begins to rise again on the addition of more base.

In a titration curve of a monoprotic acid, there is only one region in which the equivalence point is obtained corresponding to the point of acid of dissociation of all its protons.

In the titration curve of a triproprotic acid, three equivalent points are obtained corresponding to the point of dissociation of each of three protons of the triprotic acid.

The titration curves are shown below

Answer:

The particles have a medium amount of kinetic energy and slide past one another

Explanation:

If particles move at a high rate of speed its gas, and if they vibrate in place and they have a fixed volume and shape its probably a solid. So a medium amount of kinetic enery is correct.

The approximate initial boiling point of Magnesium chloride solution has been 102.33 degree Celsius.

The pure water has boiling point 100 degree Celsius. With the addition of the solvent, the boiling point has been increased. The change in the boiling point ([tex]\Delta T_b[/tex]) has been given as:

[tex]\Delta T_b=i.K_b.b[/tex]

Where, i has been the van't Hoff factor

[tex]K_b[/tex] has been the ebullioscopic constant

b has been the molality of the sample

The dissolution of magnesium chloride in water has been given as:

[tex]\rm MgCl_2\;(aq)\;\rightarrow\;Mg^2^+\;+\;2\;Cl^-[/tex]

The i has been the amount of molecules that has been formed by the dissociation of 1 molecule. The dissociation of Magnesium chloride has been resulted in the 1 Mg and 2 Cl. Thus, the i for Magnesium chloride has been 3.

The molality (m) of the solution has been given as:

[tex]m = \dfrac{m_s_o_l_u_t_e}{mwt}\;\times\;\dfrac{1000}{m_s_o_l_v_e_n_t}[/tex]

Where, [tex]m_s_o_l_u_t_e=285\;\text {g}\\m_s_o_l_v_e_n_t=2\;\text{kg}\\mwt=95.211\;\text{g/mol}[/tex]

Substituting the values, molality of the Magnesium chloride solution (b) can be given as:

[tex]b=\dfrac{285}{95.211}\;\times\;\dfrac{1}{2}\;\text{m}\\b=1.49\;\text{m}[/tex]

The molality of the solution has been 1.49 m.

Substituting the values for change in temperature:

[tex]\Delta T_b=3\;\times\;0.52\;\times\;1.49\;^\circ \text C\\\Delta T_b=2.33\;^\circ \text C[/tex]

The rise in boiling temperature with the addition of 285 g of Magnesium chloride has been 2.33 [tex]\rm ^\circ C[/tex]. Since, the initial temperature for pure solvent has been 100 degree Celsius.

The initial temperature of Magnesium chloride solution has been the sum of two. Thus:

[tex]\text {Initial temperature}=100^\circ \text C\;+\;2.33\;^\circ \text C\\\rm Initial\;temperature=102.33\;^\circ C[/tex]

The initial temperature of magnesium chloride solution has been 102.33 degree Celsius.

Answer:

a. more than the earth pull on the moon sorry if false

Answer: 35.6 g/mol

Explanation: I guessed and got it correct

The molar volume of any gas behaving ideally at STP is 22.414 L. The molar mass of the gas at STP is 35.59 g.

The molar mass of a substance is defined as the mass of one mole of molecules. In other words one gram molecular mass of a substance is same to its molar mass in g mol⁻¹.

The molar mass of a substance can be obtained by adding the atomic masses of each elements.  At 0°C and 1 atm, 1 mole of any gas behaving ideally occupies a volume of 22.414 L.

Here 5.00 L of the gas at STP has a mass of 7.94. Then the molar mass of 22.414 liters of the gas can be calculated as:

7.94 × 22.414/5.00 = 35.59 g.

Thus the molar mass of the gas is 35.59 g.
