Is the reaction of nitrogen gas and hydrogen gas to give ammonia a redox reaction?.

The number of moles of carbon in the sample is 4x.

To find the number of moles of carbon in the sample of nickel tetracarbonyl, we first need to calculate the molar mass of the compound. Nickel tetracarbonyl has a molar mass of 170.73 g/mol. This means that for every mole of nickel tetracarbonyl, there are 4 moles of carbon.

Assuming the chemical engineer has determined the number of moles of nickel in the sample to be x, we can calculate the number of moles of carbon as follows:

4 moles of carbon / 1 mole of nickel tetracarbonyl = 4x moles of carbon / x moles of nickel tetracarbonyl

Therefore, the number of moles of carbon in the sample is 4x. The number of significant digits in the answer will depend on the number of significant digits in the measurement of the number of moles of nickel. If the measurement has, for example, 3 significant digits, then the answer for the number of moles of carbon will also have 3 significant digits.

Explanation:

Hydrogen has one electron in its outermost shell, while fluorine has seven electron in its outermost shell, hence both hydrogen and fluorine needs a single electron to complete its outermost shell. That's why there is a single bond between hydrogen and fluorine.

Both hydrogen and fluorine share one electron with each other for the completion of their outermost shell. So the correct option is C.

In chemistry, the interatomic linkage that can be formed between atoms of the same or different elements and is due to the sharing of an electron pair between two atoms is called a covalent bond.

The kind of bonding is the result of an electrostatic force of attraction of their nuclei for the same electrons so that they can complete their octet. When the bonded atoms have lower total energy than that of widely separated atoms, a covalent bond is formed m

The inorganic substances hydrogen, nitrogen, chlorine, water, and ammonia (H2, N2, Cl2, H2O, NH3) and also all the organic compounds are the molecules that have covalent bonding. In the case of structural representations of molecules, this type of bonding is indicated by solid lines that connect pairs of atoms.

Therefore the correct option is C.

Answer:

mgh is the formula for potential energy

The pressure inside a container of gas increases if more gas is added to the container due to the increase in the number of molecules striking the walls of the container per unit time and the increase in the force of the collisions between the molecules and the walls of the container.

Pressure is defined as force per unit area and is usually measured in atmospheres (atm), millimeters of mercury (mmHg), or kilopascals (kPa).The molecules of gas in a container are in constant motion and collide with the walls of the container. When more gas is added to the container, the molecules have less space to move around and collide with the walls more frequently.

This leads to an increase in the number of collisions per unit time and therefore an increase in the force per unit area exerted on the walls of the container. This increase in force leads to an increase in pressure inside the container.In summary, the pressure inside a container of gas increases if more gas is added to the container due to an increase in the number of collisions and the force of the collisions between the molecules and the walls of the container.

The concentration of the concentrated sulphuric acid is 0.16 mol/L.

a)Calculate the concentration of the solution. The molecular formula of sodium hydroxide is NaOH.

Its molar mass is = 23+16+1 = 40g/mol. We are given the weight of NaOH which is 8.0g. To calculate the concentration we use the formula given below: concentration=(weight of solute)/(molar mass of solute x volume of solution)

Now we plug in the given values to calculate the concentration.concentration = (8.0 g)/(40 g/mol x 250 cm³)=0.08mol/L

b)25cm³ of the same standard solution is neutralized by adding 40cm³ of dilute sulphuric acid solution. The dilute acid solution was prepared by adding 10cm³ of concentrated sulphuric acid to 490cm³ of distilled water. Calculate the concentration of the concentrated acid.We are given the volume of sodium hydroxide which is neutralized by adding 40 cm³ of dilute sulphuric acid solution.We can find the concentration of the acid solution by the following formula.

Moles of NaOH = moles of H₂SO₄

Moles of NaOH = concentration of H₂SO₄  x volume of  H₂SO₄  x 1000

Moles of NaOH = 0.08 mol/L x 40 cm³ x 1000/1000 = 3.2 x 10⁻³ mol

We know that NaOH and H₂SO₄ reacts in 1:2 mole ratio from the balanced chemical equation given below:

NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

The moles of NaOH is 3.2 × 10⁻³.

Therefore, the number of moles of H₂SO₄ is half of it which is = 3.2 × 10⁻³ × ½ = 1.6 × 10⁻³

The volume of the concentrated acid is 10 cm³ which is equal to 0.01 L.

Therefore, the concentration of the concentrated sulphuric acid is given by the formula given below:

Concentration = (moles of H₂SO₄) / (Volume of the concentrated acid in Liters)

Concentration = (1.6 × 10⁻³) / (0.01 L) = 0.16 mol/L

Therefore, the concentration of the concentrated sulphuric acid is 0.16 mol/L.

a. The repeat unit molecular weight of polyethylene is 14.03 g/mol.

b. The number-average molecular weight of a polyethylene for which the degree of polymerization is 25000 is 350,750 g/mol.

Polyethylene is a thermoplastic polymer and has the chemical formula (C₂H₄)ₙ. It's a polymerized form of ethylene repeating unit that consists of only two atoms, carbon, and hydrogen. The molecular weight of polyethylene varies depending on the degree of polymerization. The degree of polymerization is a crucial factor in determining the molecular weight.

a. The repeat unit molecular weight of polyethylene can be calculated using the formula:

Molecular weight of repeat unit = atomic weight of C + atomic weight of H(2)

Molecular weight of repeat unit = 12.01 + 1.008(2)

Molecular weight of repeat unit = 14.03 g/mol

The repeat unit of polyethylene contains two hydrogen atoms and one carbon atom. Therefore, the molecular weight of the repeat unit of polyethylene is 14.03 g/mol.

b. The number-average molecular weight of a polyethylene for which the degree of polymerization is 25000 can be calculated using the following formula:

Number-average molecular weight = degree of polymerization × molecular weight of repeat unit

Number-average molecular weight = 25000 × 14.03

Number-average molecular weight = 350,750 g/mol

Therefore, the number-average molecular weight of polyethylene is 350,750 g/mol for a degree of polymerization of 25,000.

A micelle is a tiny cluster of soap molecules arranged in a spherical shape with the hydrophilic (water-loving) heads pointing outwards and the hydrophobic (water-fearing) tails pointing inwards. When soap is added to water, these micelles form, with the hydrophilic heads being attracted to the water molecules and the hydrophobic tails being repelled by them.

When soap is applied to oily or dirty surfaces, the hydrophobic tails of the micelles attach to the oils and dirt, while the hydrophilic heads remain in contact with the water. This allows the micelles to surround and trap the oils and dirt, effectively suspending them in the water. The micelles can then be easily rinsed away, taking the oils and dirt with them, leaving the surface clean.

Overall, micelles play a crucial role in allowing soap to dissolve oils and dirt in water, making it an effective cleaning agent.
Hi! A micelle is a spherical structure formed by soap molecules when they interact with water. Here's a step-by-step explanation of how micelles enable soap to dissolve oils/dirt in water:

1. Soap molecules consist of a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail.
2. When soap is added to water, the hydrophilic heads are attracted to the water, while the hydrophobic tails try to avoid it.
3. As a result, the soap molecules arrange themselves into a micelle, with the hydrophilic heads pointing outward and the hydrophobic tails pointing inward.
4. When oils/dirt come into contact with the soap solution, the hydrophobic tails of the micelle interact with the oils/dirt, trapping them inside the micelle.
5. The hydrophilic heads remain in contact with the water, allowing the micelle to be easily rinsed away, taking the trapped oils/dirt with it.

This is how micelles allow soap to dissolve oils and dirt in water, effectively cleaning surfaces.
