23. Mg tends to lose 2 electrons to have a full outer shell. What resulting ion will it have?

Answer:

2px orbital...

Orbitals are represents the wave-like behavior of an electron or pair of electrons in an atom. Therefore it shows 2pX orbital.

The four fundamental kinds of orbitals are s, p, d, and f. The spherical form of a s orbital can accommodate two electrons.

Each of the three p orbitals has the same fundamental structure but differs in its spatial orientation. Up to six electrons can fit into the p orbitals.

The s sublevel can only hold two electrons because it has one orbital. The p sublevel has three orbitals and a maximum capacity of six electrons.

The d sublevel may hold a maximum of 10 electrons due to its five orbitals. Additionally, the 4 sublevel has 7 orbitals and a maximum of 14 electrons.

Thus, it shows 2pX orbital.

The dissociation constant for ammonia (Kb) is a measure of the extent to which ammonia, NH3, dissociates in aqueous solution to form the ammonium ion NH4+ and the hydroxide ion OH-.

For given equilibrium concentrations of NH4+ and OH–, each 2 x 10^–3 M, and a concentration of NH3, 0.2 M, the value of Kb can be calculated using the expression Kb = [NH4+][OH]/[NH3 ].

After completing the given values, Kb = (2 x 10^–3 M)(2 x 10^–3 M)/(0.2 M) = 8 x 10^–7 M. The dissociation constant for ammonia is therefore Kb = 8 x 10^–7 M.

Answer:

Approximately 8.8 grams of solid KNO3 will precipitate from the solution when it's cooled from 50 degrees Celsius to 20 degrees Celsius.

Explanation:

The solubility of a solid in a liquid typically decreases as the temperature decreases. As a result, when a saturated solution is cooled, some of the solid may precipitate out of the solution.

The solubility of potassium nitrate (KNO3) in water at 20 degrees Celsius is around 42 grams per 100 milliliters of water. At 50 degrees Celsius the solubility is around 86 grams per 100 milliliters of water.

To find the mass of solid that will precipitate, we can use the difference between the solubility of KNO3 at 20 degrees Celsius and at 50 degrees Celsius.

At 20 degrees Celsius, the solubility of KNO3 is 42 g/100 mL, and at 50 degrees Celsius, the solubility is 86 g/100 mL.

So, the difference between the solubility of KNO3 at 20 degrees Celsius and at 50 degrees Celsius is 86 - 42 = 44 grams per 100 milliliters.

Since we have 20 mL of a saturated solution, we can calculate the mass of the precipitate by multiplying the difference in solubility by the volume of the solution:

44 g/100 mL * 20 mL = 8.8 grams.

So, approximately 8.8 grams of solid KNO3 will precipitate from the solution when it's cooled from 50 degrees Celsius to 20 degrees Celsius.

Please note that this is an approximate calculation and the actual amount of precipitate may vary depending on other factors such as impurities and the specific conditions of the experiment.

Explanation:

A. molecules of CaCO3 = number of moles x avogadros number

=  2.5 x 6.022 x 10^-23 =  1.5055 x 10^-22

B. the mass of 2 moles of Al2O3 is = molar mass of Al2O3 x number of moles

the molar mass of Al2O3 = 2 x molar mass of Al + 3 x molar mass of O

= 2 x 27 + 3 x 16 = 102 g/mol

the mass of Al2O3 = 102 x 2 = 204 g

C. 1 mol of Be3N2 = number of moles x molar mass of Be3N2

molar mass of Be3N2 = 3 x molar mass of Be + 2 x molar mass of N

= 3 x 9 + 2 x 14 = 55g/ mol

so the mass of 1 mol of Be3N2 is 55 g

So for the first one the conversion factor which is the first blank in your first question is (1/100) and the second blank which would be (74)(1/100) is 0.0174

The second one would have two conversion factors where the first blank would convert to grams, so the conversion factor for the first blank is (1000/1), then converting from grams to nano grams, whose conversion factor is (1,000,000,000/1).

So in general the second one is 9.1 x 10^-13 (1000/1) x (1,000,000,000/1) = .91 ng

Hope my explanation is easy to understand.- Ryan Brown indy

9.1 x 10-¹³ kg is equal to 0.91 nanograms (ng).

CONVERT MASS IN kg TO g

1000 grams = 1 kilogram

= 9.1 × 10-¹⁰ grams.

CONVERT MASS IN g TO ng

1gram = 1000000000 (10⁹) nanograms

= 9.1 × 10^(-10 + 9)

= 9.1 × 10-¹

Answer:

energy subshell

Explanation:

electron are mostly found in energy subshell.

The ability of an atom to become oxidized is related to its electronegativity. A high electronegativity implies a greater ability to pull electrons away from other atoms, resulting in increased oxidation.

The oxidizing power of a given element or molecule is proportional to its electronegativity. The term electronegativity refers to an element's ability to attract electrons to itself. An atom with a greater electronegativity can pull electrons away from an atom with a lower electronegativity.

It can be said that the greater the electronegativity of an atom, the greater its ability to become oxidized. This is due to the fact that when a substance becomes oxidized, it loses electrons, which are negatively charged. If a substance has a high electronegativity, it has a strong tendency to pull electrons towards itself, making it more susceptible to losing them.

Explanation:

The chemical reaction in blasting caps containing Lead Azide occurs at supersonic speeds, indicating a highly explosive and rapid reaction. The release of energy is sudden and violent, leading to the detonation of the blasting caps.

The detonation of blasting caps containing Lead Azide can occur at both subsonic and supersonic speeds, depending on the conditions and the specific characteristics of the reaction.

At subsonic speeds, the chemical reaction occurs relatively slowly compared to the speed of sound. The reaction proceeds through a series of chemical reactions and propagation of shockwaves within the blasting cap. The reaction front moves at speeds lower than the speed of sound, resulting in a relatively slower detonation process.

On the other hand, at supersonic speeds, the chemical reaction occurs rapidly, faster than the speed of sound. The detonation process involves a high-speed shockwave that propagates through the blasting cap, causing almost instantaneous chemical reactions and energy release. This supersonic detonation can result in a more rapid and violent explosion.

The specific speed at which the chemical reaction occurs in Lead Azide blasting caps depends on various factors such as the initiation mechanism, the confinement conditions, and the specific composition of the explosive material.

Answer:

a. The temperature should be increased.

b. 342.86K

Explanation:

Using Charles law equation as follows:

V1/T1 = V2/T2

Where;

V1 = initial volume (mL)

V2 = final volume (mL)

T1 = initial temperature (K)

T2 = final temperature (K)

According to this question, the following information were given:

V1 = 210mL

V2 = 360mL

T1 = -73°C (-73 + 273 = 200K)

T2 = ?

Using V1/T1 = V2/T2

210/200 = 360/T2

Cross multiply

200 × 360 = 210 × T2

72000 = 210T2

T2 = 72000/210

T2 (new temperature) = 342.86K

Answer:

Generally, all atoms of elements contain three sub-atomic particles- Protons(Positively-charged), Neutrons(Neutral) and Electrons(Negatively-charged).

The Magnitude of the Positive Charge possessed by the Protons and the Magnitude of the Negative Charge possessed by the Electrons cancel each other, which make the atom electrically neutral.

Hence,

Without any electrons, the magnitude of the positive and negative charges wouldn't balance, and the atom would be unstable and disintegrate almost immediately. Hence, all stable atoms should have electrons revolving around them, where the number of protons and electrons are the same, under normal conditions.

To Conclude,

Every atom of an element will have electrons arranged in different shells, or matter couldn't exist without electrons.
