The partial charges on each fluorine atom are negative. Option B) The central O atom is the correct answer. Option B

The partial charges in a molecule are determined by the electronegativity values of the atoms involved. Electronegativity is the ability of an atom to attract electrons towards itself in a chemical bond. In the case of \(F_2O\), fluorine (F) is more electronegative than oxygen.

Fluorine is the most electronegative element on the periodic table, meaning it has a high ability to attract electrons. Oxygen is also relatively electronegative but less so than fluorine. When fluorine atoms bond with oxygen, the shared electrons will be pulled more towards the fluorine atoms, creating a polar covalent bond.

In \(F_2O\), each fluorine atom will pull the shared electrons towards itself, resulting in a higher electron density around the fluorine atoms. This creates a region of partial negative charge around the fluorine atoms.

Conversely, the oxygen atom will have a region of lower electron density and, therefore, a partial positive charge. This is because the shared electrons spend more time around the fluorine atoms due to their higher electronegativity.

Option B

Nuclear Fission

Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei.

Nuclear fission is a process where the nucleus of an atom is split into two or more smaller nuclei, known as fission products. The fission of heavy elements is an exothermic reaction, and huge amounts of energy are released in the process.

At the end of the reaction, the mass is still expected to be 180g this is because in every chemical reaction, mass must be conserved.

According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".

Answer:

0.333 atm

Explanation:

Step 1: Given data

Step 2: Convert 30.0 °C to Kelvin

We will use the following expression.

K = °C + 273.15 = 30.0 + 273.15 = 303.2 K

Step 3: Calculate the final pressure of the gas

If we assume ideal behavior and constant volume, we can calculate the final pressure od the gas using Gay-Lussac's law.

P₁/T₁ = P₂/T₂

P₂ = P₁ × T₂/T₁

P₂ = 0.370 atm × 273.15 K/303.2 K = 0.333 atm

The second circle has the greatest number of species diversity .

The term genetic diversity has to do with the existence of different species in a habitat. We know that due to natural selection, only the organisms that have traits that enable them to survive longer and reproduce are better adapted in the ecosystem. Thus, other species may begin to dwindle and even disappear in the ecosystem.

Genetic diversity ensures that there are different species in the habitat. In each circle, we see that the colors represent the different species of the organisms in the habitat. The habitat with the most number of different colors is the habitat that has the greatest magnitude of species diversity.

Hence, the second circle has the greatest number of species diversity as indicated in the image attached to this answer.

Because HCl is a stronger acid than acetic acid, the pH of 0.01M acetic acid has greater value than the pH of 0.01M HCl. 2.88 is the  pH of a 0.01 M acetic acid.

Any hydrogen that comprises a material capable of giving a proton (a hydrogen ion) to another chemical is defined as acid. A base is indeed a molecule or ion that can receive a hydronium ion from just an acid.

1)Because HCl is a stronger acid than acetic acid, the pH of 0.01M acetic acid has greater value than the pH of 0.01M HCl. The pH value of stronger acid is lower.

Answer:

the plane will crash, or if it is usable or not.

The car's average speed is 116 kilometers per hour.

The entire distance traveled divided by the total time elapsed is the definition of average speed. It is typically stated in terms of the amount of time or distance per unit, such as meters per second (m/s) or kilometers per hour (km/hr).

Average speed = total distance ÷ total time

In this case, the total distance is 464 km and the total time is 4 hours.

Average speed = 464 km ÷ 4 hours

Average speed = 116 km/hr

Therefore, the car's average speed is 116 kilometers per hour.

The limiting and excess reactant can be obtained as follow:

2Mg + O₂ -> 2MgO

From the balanced equation above,

48 g of Mg reacted with 32 g of O₂

Therefore,

62.1 g of Mg will react with = (62.1 × 32) / 48 = 41.4 g of O₂

We can see from the above that only 41.4 g of O₂ is required to react completely with 62.1 g of Mg.

Thus, the limiting reactant is magnesium, Mg and the excess reactant is oxygen, O₂

The mass of the excess reactant remaining can be obtained as shown below:

Mass of excess reactant remaining = Mass given - mass reacted

Mass of excess reactant remaining = 100 - 41.4

Mass of excess reactant remaining = 58.6 g

The mass of H₂SO₄ produced can be obtained as illustrated below:

Mg + O₂ -> 2MgO

From the balanced equation above,

48 g of Mg reacted to produce 80 g of MgO

Therefore,

62.1 g of Mg will react to produce = (62.1 × 80) / 48 = 103.5 g of MgO

Explanation:

Data obtained from the question include:

Molar mass of NaCl = 58.55 g/mol

Mass of NaCl = 0.800 g

Volume = 54.6 mL

Next, we shall determine the number of mole in 0.800 g of NaCl. This can be obtained as follow:

Molar mass of NaCl = 58.55 g/mol

Mass of NaCl = 0.800 g

Mole of NaCl =?

Mole = mass /Molar mass

Mole of NaCl = 0.8/58.55

Mole of NaCl = 0.0137 mole

Next, we shall convert 54.6 mL to litres (L). This can be obtained as follow:

1000 mL = 1 L

Therefore,

54.6 mL = 54.6 /1000

54.6 mL = 0.0546 L

Finally, we shall determine the molarity of the solution as follow:

Mole of NaCl = 0.0137 mole

Volume = 0.0546 L

Molarity =?

Mol= mole /Volume

Molarity = 0.0137/0.0546

Molarity = 0.25M

Therefore, the molarity of the solution is 0.25 M

Chlorofluorocarbons (CFCs) are man-made chemicals containing chlorine and fluorine that cause ozone molecules to break down. Thus, option B is the answer.

Chlorofluorocarbons are non-toxic, synthetic compounds that contain atoms of Chlorine, Fluorine and Carbon. They are commonly used in the manufacture of aerosol sprays and are also used as solvents and refrigerants. CFCs were first introduced in 1928 by General Motors Company for its refrigerators.

While CFCs are very safe to use in most applications and are stable in the lower atmosphere, these chemicals when released to the upper atmosphere can cause significant reactions. CFCs when released into the upper atmosphere can lead to the destruction of the ozone molecules followed by the release of the UV radiation into the atmosphere.
