The insoluble AgCl can react with NH3 to form the soluble complex ion Ag(NH3)2+. Which acts as a Lewis base in this reaction? NH3 Ag+ Cl- There is no Lewis base in this reaction

Answers

Answer 1

NH3 is the Lewis base in this reaction, and it donates its lone pair of electrons to the Ag+ ion, which acts as the Lewis acid.

In this reaction, NH3 acts as a Lewis base, A Lewis base is a species that has a lone pair of electrons and can donate it to form a coordinate covalent bond with a Lewis acid. In this case, NH3 donates its lone pair of electrons to the Ag+ ion, which acts as a Lewis acid.

The Ag+ ion has an incomplete octet and is electron deficient, so it accepts the lone pair of electrons from NH3 to form the complex ion Ag(NH3)2+.

The Cl- ion, on the other hand, does not act as a Lewis base in this reaction. It is not involved in the formation of the complex ion Ag(NH3)2+ and does not have a lone pair of electrons to donate to form a coordinate covalent bond with a Lewis acid.

A sample of an oxide of nitrogen is found to contain 30.4% nitrogen. What is its empirical formula?

Answers

Answer:

If nitrogen = 30.4% then oxygen = 100-30.4 = 69.6%

divide each % value by atomic mass

N = 30.4/14 = 2.17

O = 69.6/16 = 4.35

Divide each y smaller:

N = 2.17/2.17 = 1

O = 4.35/2.17 = 2

Explanation:

"The empirical Formula will be [tex]NO_{2}[/tex]."

What is empirical formula?

In chemistry, an empirical formula is the simplest thought of the entire number quantity of atoms in a molecule.

It is given that N = 30.4%.

The % of O can be determined as: 100-30.4%= 69.65.

Now, after dividing % value with atomic mass, we get.

Mass of  N= 14 and Mass of O = 16.

N= 30.4/14= 2.17

O = 69.6/ 16= 4.35

It can be seen that N has less number as compared to O . So, divide each with 2.17.

N= 2.17/2.17 = 1

O = 4.35/2.17=2

So the empirical formula will be [tex]NO_{2}[/tex].

Answers

Answer: c. so that you use the correct energy states

Explanation:

Enthalpy is the energy release or energy produced when a chemical reaction is carried out.

Enthalpy change is calculated by substracting the energy of reactants from the energy of products.

As the energies are different for different states and thus the correct stale symbols in your balanced chemical equation must be given so that we use the correct energy values.

[please answer fast!] If the hydroxide ion concentration is 2x10^-3 M, what is the pH of the solution? Show your working.

Answers

Answer:

pH = 11.30

Explanation:

pH is defined as -log [H⁺]

To find [H⁺] from [OH⁻] -Concentration of hydroxide ion-, we must use the equilibrium of water:

H₂O(l) ⇄ H⁺(aq) + OH⁻(aq)

Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]

[H⁺] = 1x10⁻¹⁴ / [OH⁻]

[H⁺] = 1x10⁻¹⁴ / 2x10⁻³M

[H⁺] = 5x10⁻¹²M

pH = -log (5x10⁻¹²M)

pH = 11.30

how does the total mass of each object increases the amount of force that is needed to get them moving at 5 m/s increase by about 200N demonstrate newtons 2nd law

Answers

Answer:

The answer is below

Explanation:

Newton's second law of motion states that the force applied to an object is directly proportional to the rate of change of momentum with respect to time, going in the same direction as the force.

Let F = force, m = mass of object, v = velocity of object, mv = momentum.

F = d/dt(mv) = m(dv / dt) = ma; a = acceleration.

Let us assume that the object starts from rest to 5 m/s within 1 seconds, hence:

F = m(dv / dt)

200 N = m[(5 m/s - 0 m/s) / (1 s)]

200 = 5m

m = 40 kg

Answers

Answer: The ground state electronic configuration of an atom having atomic mass number 37 and number of neutrons 20 is [tex]1s^22s^22p^63s^23p^5[/tex]

Explanation:

Atomic number is equal to the number of protons.

Mass number is the sum of number of neutrons and number of protons.

Mass number =  number of neutrons + number of protons

37 = 20 + number of protons

number of protons = 17

The atomic number is specific to an element, and the element with atomic number 17 is chlorine.

Electronic configuration represents the total number of electrons that a neutral element contains.

What will be the temperature and pressure of the gas in the cylinder after 5 minutes? What will be the rate of change of the gas temperature at this time? Nitrogen can be considered to be an ideal gas with Cp*=30 J/mol.K.

Answers

Answer:

Final temperature = 152.57K,

Pressure = 0.6907 bar.

dT/dt = - 1,151 K/s.

Explanation:

The first thing to do here is to write out the equation for mass balance as given below:

dN/dt = N -------------------------------------------------------------------------------------------(1).

N = P/T, then, substitute the values given in the question into:

d[p/T]/ dt = [- 4.5/28 × 8.314]/0.15 = - 8.9 × 10⁻⁵ bar/K.s.

Thus, there is the need to integrate, Integrate [p/T]f = 10/320 - 8.9 × 10⁻⁵ bar/K.s. ------------------------------------(2).

NB; fT = final temperature, fP = final pressure and iT = initial temperature.

Also, [ fT]³⁰/₈.₃₁₄/ [fP] = [iT]³⁰/₈.₃₁₄/ Pi] = [ 320]³⁰/₈.₃₁₄/ 10.

Therefore, [fT]³⁰/₈.₃₁₄ = 109.52 × 10⁶.

Final temperature=  [fP]³⁰/₈.₃₁₄ × 169.05.

Note that fP/ [fP]³⁰/₈.₃₁₄ × 169.05 = 10/320 - 8.9 × 10⁻⁵.

Therefore, [fP]¹ ⁻ ³⁰/₈.₃₁₄ = 0.7651.

Hence, Final temperature = 152.57K,

Pressure = 0.6907 bar

dT/ dt = N[RT]² / Cv . PV.

R = 30 - 8.314 = 21.86 J/mol K.

Then, the rate of change of the gas temperature at this time = dT/dt = - 1,151 K/s.

How many pounds of ice are required to absorb 4900 kJ of heat as the ice melts? The heat of fusion of water is 0.334 kJ/g.

Answers

Answer:

m = 32.34 pounds of ice.

Explanation:

In this case we need to use the following expression of heat:

q = m * ΔHf   (1)

Where:

q: heat absorbed in J or kJ

m: mass of the compound in g

ΔHf: heat of fusion of the water in kJ/g

We are asked to look for the mass of ice in pounds, so after we get the grams, we need to convert the grams to pounds, using the following conversion:

1 pound --------> 453.59 g   (2)

So, we have the heat and heat of fusion, from (1) let's solve for the mass, and then, using (2) the conversion to pounds:

q = m * ΔHf  

m =  q / ΔHf

m = 4900 / 0.334 = 14,670.66 g of ice

Now, the conversion to pounds:

m = 14,670.66 g * 1 pound/453.59 g

m = 32.34 pounds of ice.

PLEASE MARK ME BRAINLIST

Electrons move freely among positively charged ions. This is the characteristics of a metallic bond. Therefore, the correct option is option B.

Valence electrons in a metallic link are not bound to a specific pair of atoms, but rather travel freely among a "sea" of positively charged metal ions. These electrons are not assigned to any specific atom and are shared by all metal ions in the metallic lattice.

The electron sea model depicts the valence electron arrangement as a "sea" of negatively charged electrons encircling positively charged metal ions. Metals have strong electrical and thermal conductivity due to electron mobility.
