The volume of the ethanol that has a density of ethanol is 0.789 g/cm³ is 209.13cm³.

The volume of a substance can be calculated by dividing the mass of the substance by its density as follows:

Volume = mass ÷ density

According to this question, the density of ethanol is 0.789 g/cm³. A flask holds 165.0 g of ethanol and the volume can be calculated as follows:

Volume = 165.0g ÷ 0.789g/cm³

Volume = 209.13cm³

Therefore, the volume of the ethanol that has a density of ethanol is 0.789 g/cm³ is 209.13cm³.

The price of gas in Paris is 1.29 euro per liter . the price of gasoline in dollars per gallon is 6.1039 dollar per gallon.

The price of gas in Paris = 1.29 euro per liter.

we have to convert this in dollar per gallon,

it is given that ,

1 euro is equal to = 1.25 dollar

also, in one liter =0.264172 gallons

now, conversion to dollar per gallons are :

1.29 euro per liter =  (1.29 × 1.25 ) / 0.264172 dollars per gallon

                             =  1.6125 / 0.264172 dollars per gallon

                             =  6.1039 dollars per gallon

Thus,The price of gas in Paris is 1.29 euro per liter . the price of gasoline in dollars per gallon is 6.1039 dollar per gallon.

Hydrogen quickly can not pressurized steel cylinders because" The low volumetric energy density of hydrogen makes storage a challenge. Since it would be the lightest and most basic element, it is even lighter that helium it is quickly lost in the environment."

A very minor hydrogen leak could occur if hydrogen interacts with the metal or passes completely through to the outside surface. Metal's mechanical characteristics deteriorate when hydrogen is present in the metal's lattice (e.g., fatigue as well as fracture resistance). Hydrogen embrittlement would be a phenomenon (HE).

Intensifying the density and adding additional gas to the tank are two effects of cooling compressed hydrogen gas. Liquid nitrogen was frequently used to chill the system down to 77 K, which triples its volumetric capacity when compared to uncooled hydrogen.

The mass of ether produced is 111.5 g.

Let us recall that a chemical reaction is said to have occurred when there is an interaction between reactants that leads to the formation of products. Usually, a given percentage of the reactants is always converted into products.

Now;

2[tex]CH_{3} CH_{2} OH[/tex](l) → [tex]CH_{3} CH_{2}OCH_{2}CH_{3}[/tex](l) + [tex]H_{2} O[/tex](l)

Number of moles of ethanol reacted = 207 g /46 g/mol

= 4.5 moles

If 2 mole of ethanol produced 1 mole of diethyl ether

4.5 moles of ethanol produced 4.5 moles *  1 mole/2 mole

= 2.25 moles

Theoretical yield of diethyl ether = 2.25 moles  * 74 g/mol = 166.5 g

We now have to find the actual yield hence;

When studying quantum mechanics, the de Broglie wavelength is a key idea. De Broglie wavelength is the wavelength () that is connected to an item in relation to its momentum and mass.

Typically, a particle's force is inversely proportional to its de Broglie wavelength.

Assuming that the smallest measurable wavelength in an experiment is 0.830 fm , what is the maximum mass of an object traveling at 171 m⋅s−1 for which the de Broglie wavelength is observable?

We know:

According to the following equation, an object's de-Broglie wavelength solely depends on its momentum:

λ = h/p = h/m*v, where,

By rearranging the above equation, the object's mass can be written as:

        m = h/λv

The maximum mass and the minimum de Broglie wavelength of the item are inversely correlated because the two quantities are inversely proportional to one another. When we enter the values provided, we get:

        m = {6.626×10^(−34) J⋅s} / {0.330 fm × 157 m/s}

The [OH] of the given solution is  0.000000000043652 M and the pH of the solution is equal to 3.36.

Given in the question

Concentration of the Hydronium Ion=  [H+] =  0.00043 M

We know that,

pH is a figure that uses a logarithmic scale with 7 as neutral, where lower values are more acidic and higher values are more alkaline, to represent the acidity or alkalinity of a solution. The hydrogen ion concentration (c), expressed in moles per liter, determines the pH, which is equal to -log10(c).

So the pH of the given solution is

pH = -log10[0.00043]

pH = -(-3.36)

pH = 3.36

So the pH of the given solution is 3.36.

We know that at 25 °C, the sum of pH and pOH of the solution is equal to the 14

pH + pOH = 14

Put in the values, we get

3.36 + pOH = 14

pOH = 14 - 3.36

pOH = 10.64

Now, the pOH of the solution is given by  -log10[OH].

Put in the values, we get

-log10[OH] = 10.36

Taking antilog on both sides, we get

[OH] = 0.000000000043652 M

Therefore, the [OH] = 0.000000000043652 M and pH =  3.36.

1. The volume of 44 g of N₂ at STP is 35.2 L

2. The volume of 0.25 mole of NH₃ at STP is 5.6 L

1 mole of gas = 22.4 L

1 mole of N₂ = 22.4 L at STP

But

1 mole of N₂ = 28 g

Thus, we can say that,

28 g of N₂ = 22.4 L at STP

Therefore,

44 g of N₂ = (44 × 22.4 L) / 28 g

44 g of N₂ = 35.2 L

Thus, 44 g of N₂ has a volume of 35.2 L at STP

1 mole of NH₃ = 22.4 L at STP

Therefore,

0.25 mole of NH₃ = (0.25 × 22.4 L) / 1 mole

The law of conservation of mass, also known as the principle of mass conservation, in physics and chemistry states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time because the mass of the system cannot change and therefore quantity cannot be added to or subtracted.

Conservation of Mass.

Antoine Lavoisier discovered in 1789 that mass is neither created nor destroyed in chemical reactions, which led to the formulation of the Law of Conservation of Mass. That is to say, the mass of any one element at the start of a reaction will be equal to that element's mass at the conclusion of the reaction. The overall mass will remain constant over time in any closed system if we take into account all reactants and products in a chemical reaction. Lavoisier's discovery transformed science and served as the cornerstone for contemporary chemistry.

Because naturally occurring elements are extremely stable under the circumstances present on the Earth's surface, the Law of Conservation of Mass is valid. The majority of elements are created in stars and supernovae through fusion processes. Therefore, atoms do not change into other elements during chemical reactions in the ordinary world of Earth, from the top of the tallest mountain to the bottom of the deepest ocean. As a result, each atom that makes up life and nonliving stuff is extremely old and has a past.
