answer : Pauli's exclusion principle

Explanation:

The principle that was disobeyed is Pauli's exclusion principle this is because the  Pauli's exclusion principle states that no two electrons can have the same set of quantum number.

In Box A the two electrons , have the same spin which means  they have the same quantum number ( disobeys Pauli's exclusion principle )

Answer:

Explanation:

Expression for capillary rise is as follows

h = 2T / ρ g r where T is surface tension , ρ is density of liquid and r is radius of capillary tube.

T = .032 J m⁻²

ρ = .71 g / cm³

= 7100 kg / m³

r = .1 x 10⁻³ m = 10⁻⁴ m

h = 2 x .032 / (7100 x 9.8 x 10⁻⁴ )

h = .0092 m

= 9.2 mm .

Answer:

C3H6O

Explanation:

The percentage composition of the elements in the compound are given as follows:

62.1 % carbon = 62.1g of C

10.5 % hydrogen = 10.5g of H

27.6 % oxygen = 27.6g of O

Next, we convert each mass to mole by dividing by their molar/atomic mass

C = 62.1/12 = 5.175mol

H = 10.5/1 = 10.5mol

O = 27.6/16 = 1.725mol

Next, we divide each mole value by the smallest mole value (1.725)

C = 5.175mol ÷ 1.725 = 3

H = 10.5mol ÷ 1.725 = 6.086

O = 1.725mol ÷ 1.725 = 1

The empirical ratio approximately of C:H:O is 3:6:1, hence, the empirical formula is C3H6O

Answer:

Maximum amount of NaCl that can be Dissolved in 100g of water at 90'C

Explanation:

In fact, you can expect to be able to dissolve no more than 40 g of sodium chloride per 100 g of water at 80∘C . So, at 80∘C , you will have an unsaturated solution if you dissolve less than 40 g of sodium chloride, and a saturated solution if you dissolve about 40 g of sodium chloride

Answer:

2.94 × 10²⁴ molecules

Explanation:

Step 1: Given data

Volume of acetone (V): 360 mL (360 cm³)

Density of acetone (ρ): 0.788 g/cm³

Step 2: Calculate the mass of acetone (m)

Density is equal to the mass of acetone divided its volume.

ρ = m/V

m = ρ × V

m = 0.788 g/cm³ × 360 cm³ = 284 g

Step 3: Calculate the moles corresponding to 284 g of acetone

The molar mass of acetone is 58.08 g/mol.

284 g × 1 mol/58.08 g = 4.89 mol

Step 4: Calculate the number of molecules in 4.89 moles of acetone

We will use Avogadro's number: there are 6.02 × 10²³ molecules of acetone in 1 mole of molecules of acetone.

4.89 mol × 6.02 × 10²³ molecules/1 mol = 2.94 × 10²⁴ molecules

Answer:

The answer is "Choice A".

Explanation:

In this question, the choice A is wrong because when the copper panels on houses produce a patina (copper oxide) through occur as a consequence of reactions from oxygen and water in the air, these reaction does not have low activation energy because lower activation energy that is stored in a faster response rate.

Answer:

In thin-layer chromatography, the retention factor (Rf) is used to compare and help identify compounds. The Rf value of a compound is equal to the distance traveled by the compound divided by the distance traveled by the solvent front (both measured from the origin).

Answer:

0.1023 moles

Explanation:

We have this reaction

Na2HPO4 → 2Na+ + NPO4-

1 mole gives us 3 ions

Na+ has 2 ions to it

NPO4 has 1 ion

2 + 1 = 3

We multiply 3 with the number of moles to get the answer to this question

3 x 0.0341

= 0.1023 moles

So we conclude that total moles released when dissolved in water is equal to 0.1023

Answer:

11.25 moles of O₂.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O

From the balanced equation above,

1 mole of C₃H₈ reacted with 5 moles of O₂.

Finally, we shall determine the number of mole of O₂ needed to react with 2.25 moles of C₃H₈. This can be obtained as follow:

From the balanced equation above,

1 mole of C₃H₈ reacted with 5 moles of O₂.

Therefore, 2.25 moles of C₃H₈ will react with = 2.25 × 5 = 11.25 moles of O₂.

Thus, 11.25 moles of O₂ is needed for the reaction.

Answer:

Explained below.

Explanation:

The difference between the two of them will be considered from their electrostatic potential maps.

First of all the major difference is that ammonia molecule(NH3) has a lone lone pair of electron on the N atom.

Due to the this lone pair of electron on the N - atom of ammonia, it's bond angle will be slightly lesser than that of ammonium ion.

Therefore, In the electrostatic potential map of NH3, the charge distribution will not be symmetrical for the fact that there is electron rich N atom and so the N atom will be more red than the 3 hydrogen atoms (H atoms).

Whereas, the electrostatic potential map of NH4+ (ammonium ion) will be symmetrical due to the even/symmetrical distribution of all the 4 hydrogen atoms surrounding the central Nitrogen atom.

Also, the Nitrogen atom here in ammonium ion will have a lower electron density than the Nitrogen atom that's present in ammonia molecule due to the bonding existing between the lone pair electron and the Hydrogen atom

Answer:

True

Explanation:

The Coriolis effect is the deflection of winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of Earth's rotation. This statement is true.

Circulating air is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere as the Earth rotates on its axis. The Coriolis effect refers to this deflection.

Because of the rotation of the Earth, we experience an apparent force known as the Coriolis force. The wind is deflected to the right in the northern hemisphere and to the left in the southern hemisphere as a result of this.

There is no curving of the object's path as measured relative to the Earth's surface because there is no turning of the Earth's surface  underneath a horizontally and freely moving object at the equator.

Thus, There is no Coriolis effect because the object's path is straight.

Answer:9.03*10^23

Explanation:

Answer:

44 grams of CO₂ will be formed.

Explanation:

The balanced reaction is:

C + O₂ → CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

Being the molar mass of each compound:

By stoichiometry the following mass quantities participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

If 12 grams of C react, by stoichiometry 32 grams of O₂ react. But you have 40 grams of O₂. Since more mass of O₂ is available than is necessary to react with 12 grams of C, carbon C is the limiting reagent.

Then by stoichiometry of the reaction, you can see that 12 grams of C form 44 grams of CO₂.

44 grams of CO₂ will be formed.
