Answer:
113 km³
Explanation:
Step 1: Given data
Radius of the meteor (r): 3 km
Step 2: Calculate the volume (V) of the meteor
The meteor is spherical. Given the radius (r), we can calculate the volume of a sphere using the following expression.
V = 4/3 × π × r³
V = 4/3 × π × (3 km)³
V = 4/3 × π × 27 km³
V = 113 km³
The volume of the meteor is 113 km³.

Answer:
0.113 M
Explanation:
Since B and D are on opposite sides of the reaction, the concentration of D increases when the concentration of B decreases. The amount by which D increases is determined by the coefficients of B and D in the balanced chemical equation:
[D]=(0.045 M)=0.113 M.

Answer:
0.623 moles of H₂O.
Explanation:
- balanced equation: 2C₂H₆ + 7O₂ -> 4CO₂+ 6H₂O
Given:
- 6.23g of C₂H₆
- C₂H₆ molar mass is 30
solve for moles of C₂H₆
- moles = mass/mr
- moles = 6.23/30
- moles = 0.2077
solve for moles of H₂O using molar ratio
- 2C₂H₆ : 6H₂O
- 2 : 6
- 0.2077 : 0.623
Therefore, found that 0.623 moles of H₂O is produced.

The substance that is used for the industrial preparation of methyl diantilis is called the sodium borohydride (NaBH4).
Industrial preparation of methyl diantilis:
Methyl diantilis is a substance that has an elegant fragrance with a similar olfactive note to Isoeugenol.
It is used as complexing agent for vanilla, tobacco, leather and fruit accords.
It can be prepared industrially by the reduction of 3-ethoxy-4-hydroxybenzaldehyde (ethyl vanillin) to 3-ethoxy-4-hydroxybenzyl alcohol.
To reduce the aldehyde group of 3-ethoxy-4-hydroxybenzaldehyde, sodium borohydride is added in the industrial preparation process.
The sodium borohydride (NaBH4) produces a phenol functional group with other reactants leading to reduction of aldehyde group and increase in the solubility of reactants.
Therefore, the substance that is used for the industrial preparation of methyl diantilis is called the sodium borohydride (NaBH4).

Answer:
Sodium Borohydride (NaBH₄)
Explanation:
Methyl diantilis (2-Ethoxy-4-(methoxymethyl)phenol) is a fragrance compound which smells like Vanilla. This compound is being synthesized from 3-ethoxy-4-hydroxybenzaldehyde also known as Ethyl Vanillin in two steps.
Step 1: Reduction of Aldehydic Group on Ethyl Vanillin:
The benzaldehyde derivative is treated with a mild reducing agent i.e. NaBH₄ (Sodium Borohydride). NaBH₄ is a source of Hydride (H⁻) ion and undergoes nucleophilic substitution reaction yielding 2-ethoxy-4-(hydroxymethyl)phenol.
Step 2: Etherification of 2-ethoxy-4-(hydroxymethyl)phenol:
In the second step 2-ethoxy-4-(hydroxymethyl)phenol is treated with Methanol in the presence of strong acidic polymeric resin known as Amberlyst-15-wet resulting in the formation of Methyl diantilis as shown in attached figure.

pH scale is used to measure the acidity or alkalinity on a scale of 0-14 where 0-6.9 is the acidic region , 7.1-14 is the basic region and 7 is for the neutral substance. We can calculate the concentration of proton from pH.
where is the concentration of proton
As per the question ,the pH of coffee is 5.6 and we need to find the concentration of proton so putting the values in the above equation, we get

The gas particlesmove randomly (a), collide into each other (b) and have high kinetic energy (d).
Which of the following best describe gas particles?
a moving randomly.YES. They move in all directions without a predefined path.
b collide into each other.YES. They collide into each other and against the walls of the container they are in.
c move slow.NO. They move very rapidly.
d high kinetic energy.YES. Their high kinetic energy is a consequence of their fast movement.
e moving orderly.NO. They move in a random fashion.

Hence an aerosol is a colloidal solid or liquid suspended in a gas Smoke or fog, for example.
define aerosol?
Aerosol is a system of equally dispersed, finely divided liquid or solid particles passing through a gas, often air. Dust and other aerosol particles, which serve as the nuclei for condensation and freezing, are crucial to the precipitation process.
Which two forms of aerosols exist?
Secondary aerosols develop when gas is converted into a particle, whereas primary aerosols are made up of particles that are added directly to the gas. Key aerosol categories include sulfates, organic carbon, black carbon, nitrates, mineral dust, and sea salt. These substances typically clump together to create complicated mixtures.
