When the Hydrogen sulfide decomposes according , the equilibrium concentration of H₂ is 0.0019 mol/L.

Given that :

Numbers of moles of H₂S = 0.49 moles

The Volume = 3.0 L

The Equilibrium constant = 9.30 × 10⁻⁸

The reaction is given as :

2H₂S    ⇄   2H₂(g)  +  S₂(g)

Initial concentration = 0.49 / 3

                                  = 0.16 mol

                     2H₂S    ⇄             2H₂(g)  +         S₂(g)

Initial         0.9166                           0                           0

Change       -2 x                               +2 x                      + x

Equilibrium   (0.16 - 2x)                   2x                         x

kc  = [H₂]²[S₂]² / [H₂S]²

9.30 × 10⁻⁸ = (2x)²(x²) / ( 0.16 - 2x)²

x = 9.5 × 10⁻⁴

The equilibrium concentration for H₂ = 2x

                                                              = 2 ×  9.5 × 10⁻⁴

                                                              = 0.0019 mol/L

Density of a block of aluminum occupies a volume of 10mL and has a mass of 40 g is 4g/ml.

Define density.

A material's density is determined by how closely it is packed. As the mass per unit volume, it has that definition. The relationship between density and volume and mass is inverse.

The density rises if the volume remains constant while the amount of matter increases. Density drops when volume grows without accompanying increases in mass. When a substance is heated, the molecules move faster and slightly farther apart, taking up more space and causing the density to drop. When something is cooled, the molecules slow down and get a little closer together, taking up less space and becoming denser.

D = M/V

Mass, M is 40 g.

Volume, V of 10mL

Matter has evolved from the four elements to the new understanding of the quantum dimensions of matter.

Our understanding of matter has changed significantly over time. In ancient times, matter was thought to be made up of four elements: earth, air, fire, and water. The Greek philosopher Aristotle proposed a system of matter in which everything was made up of combinations of these four elements.

More recently, scientists have been studying the properties of dark matter and dark energy, which are thought to make up most of the universe, but are not yet well understood.

Overall, our understanding of matter has evolved from the ancient belief in four elements, to the modern understanding that matter is made up of atoms, which are made up of smaller subatomic particles and are affected by particle fields and quantum mechanics.

1.81 moles are in 500 grams of BeCr2O7.

Molar mass of BeCr2O7 = 276.095 g/mol

500 g / 276.095 g/mol = 1.81 moles

What is moles?

Moles is a unit used to measure the amount of a substance. It is defined as the amount of a substance that contains the same number of atoms, molecules, ions, or electrons as the number of atoms in 12 grams of carbon-12 (C-12). This means that one mole of any substance will contain the same number of atoms, molecules, ions, or electrons as one mole of C-12. Moles are used in chemistry to measure the quantity of a substance. For example, when a chemist mixes two solutions together, they can use moles to calculate the amount of each substance that was mixed.

A clear and precise depiction of the reactants and products is required for a comprehensive arrow-pushing mechanism.The reaction between H3C-H and CH3CH2OH occurs under acid-catalyzed .

conditions as follows: The acid catalyst, such as H2SO4, transfers a proton (H+) to the alcohol molecule's oxygen atom.resulting in the formation of a hydroxyl ion (CH3CH2O-). This hydroxyl ion is nucleophilic and attacks the alkane molecule's electrophilic carbon atom, generating a tetrahedral intermediate. As the intermediate forms, a link between the carbon atom and the proton is broken, resulting in the formation of a carbocation (H3C+). The link between the oxygen atom and the hydroxyl ion is also broken, resulting in the formation of a water molecule (H2O) and a new alcohol molecule (CH3CH2OH). The electron-rich oxygen atom stabilizes the carbocation, and the reaction is completed with the production of a new carbon-oxygen bond, yielding the result molecule CH3C-O-CH3. Under acid-catalyzed conditions, the overall arrow-pushing mechanism for this reaction is (Protonated alcohol) -> H3C+ + CH3CH2O- (Carbocation intermediate) -> CH3C-O-CH3 + H2O (Product).

Answer :a chemical reaction in which a more reactive element displaces a less reactive element from its compound

Explanation:

Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.

Answer:

Chemical reactions known as displacement reactions occur when a more reactive element removes a less reactive element from a molecule.

The induced-fit hypothesis of enzyme-substrate interaction illustrates that there is a conformational change in the active site of the enzyme when a substrate binds to it.

According to the induced-fit model, a substrate attaches to an active site, and the two of them slightly alter their shapes to form the perfect fit for catalysis. By bringing substrates together in the best possible orientation, enzymes encourage chemical reactions by establishing the perfect chemistry for the reaction to take place. According to the induced fit hypothesis, an enzyme's active site is not architecturally ideal for substrate binding while it is in the unbound state, or when it is not binding to a substrate. Refer to the image attached for the cartoon illustration.

This induced fit theory extends the lock-and-key idea proposed 100 years ago. In addition to explaining regulatory and cooperative effects, the new theory put out by D. E. Koshland, Jr. in 1958 also provides some new specificity notions. This theory states that an enzyme's unbound active region is not structurally suitable for substrate binding (i.e., not bound to the substrate).

Explanation:

A gas sample consisting of 2.0 moles of hydrogen and 1.0 mole of oxygen is collected over water at 29ºC and 75 kPa. 48 kPa is the partial pressure of the hydrogen in this sample. Therefore, option B is correct.

The term partial pressure is defined as the pressure that a gas, in a mixture of gases, would exert if it alone occupied the whole volume occupied by the mixture.

Total number of mole = 2 + 1

= 3 moles

Temperature = 29ºC

Total pressure = 75 kPa

partial pressure = mole fraction x total pressure

P V = n R T

The underwater mountain range that is shown in the image is the Mid-Atlantic Ridge. This range runs down the center of the Atlantic Ocean, and is a part of the global mid-ocean ridge system.

The Mid-Atlantic Ridge is a divergent plate boundary, which means that it is an area where two tectonic plates are moving away from each other. As the plates move apart, magma from the Earth's mantle rises to the surface and cools, forming new crust. This process of seafloor spreading is what creates the underwater mountain range.

One possible explanation for the location of the Mid-Atlantic Ridge in the middle of the ocean is that it is a response to the convective motion of the Earth's mantle. The mantle is made up of hot, dense rock that is constantly moving around.

Another possible explanation is that the Mid-Atlantic Ridge is the result of past tectonic activity. The Atlantic Ocean was formed by the separation of the supercontinent Pangea into two parts, Laurasia and Gondwana. The ridge is a remnant of the rift that separated these two supercontinents.

In all, the Mid-Atlantic Ridge is a fascinating feature that provides important information about the Earth's geology and tectonic activity. Its location in the middle of the ocean is a reminder of the dynamic nature of our planet, and the ongoing process of seafloor spreading that is constantly shaping the Earth's surface.
