For the reaction H2O(g) + Cl2O(g) → 2HCIO(9), you know S rxn and Sosys and S° of HCIO(g) and of H2O(g). Write an expression that

Liono4ka [1.6K]

The expression that can be used to determine Cl2O(g) is ;

$S_{cl_{2}o(g) } ^{o} = 2S_{HCIO(g)} ^{o} - S_{H_{2}O(g) }^{o} - \beta S_{rxn} ^{o}$

<h3>Determine an expression that can be used to determine Cl2O(g)</h3>

The general expression for ΔS°rxn of a chemical reaction

ΔS°rxn = ∑mS°products - ∑nS°reactants

where ; m and n = stoichiometry coefficients

Considering the given reaction : H₂O(g) + Cl₂O(g) → 2HCIO (g)

$\beta$ S°rxn = $2S_{HCIO(g)} ^{o} - S_{H_{2}O(g) } ^{o} - S_{Cl_{2}O } ^{o}$ ------- ( 2 )

Rearranging the equation above

$S_{cl_{2}o(g) } ^{o} = 2S_{HCIO(g)} ^{o} - S_{H_{2}O(g) }^{o} - \beta S_{rxn} ^{o}$

Hence we can conclude that The expression that can be used to determine Cl2O(g) is ;

$S_{cl_{2}o(g) } ^{o} = 2S_{HCIO(g)} ^{o} - S_{H_{2}O(g) }^{o} - \beta S_{rxn} ^{o}$

Why is there an attraction between the two ions in this chemical bond?

ladessa [460]

<u>Answer:</u>

<u>A metallic bond is a force of attraction between charged metal ions and the electrons that are in the delocalized bond, which covers the assembly of ions. A covalent bond is the force of attraction between the nuclei of atoms, and the electrons shared between them. </u>

<u />

<u>Explanation:</u>

<u> A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond can be generated by electrostatic attraction between charged ions (for example, ionic bonds) or by electron sharing (for example, covalent bonds). </u>

I hope this helps you :)

Volatile organic solvents have been implicated in adverse health effects in industrial workers. Greener methods are phasing thes

Viktor [21]

Volatile organic solvents consists of variety of chemical gases which are emitted in form of solid or liquids.

Everyday household products also emit these compounds which includes wax, paints which are applied on walls of the house.

These compounds are called as volatile substance because they have higher vapour pressure, and lower boiling points than as compared to the other compounds.

Common emissions sources of VOCs include dry cleaners; auto body shops; cars, trucks, and buses etc.

Volatile organic solvents play a vital role in the creation of ground-level ozone. Ground-level ozone can irritate the eyes, nose, and throat, and can aggravate asthma and other lung diseases, including bronchitis.

What is the kinetic energy of a 328 kg object that is moving at s speed of 10 m/s

Advocard [28]

16400 Joules is the kinetic energy of a 328kg object with a velocity of 10m/s.

<h3>What is the kinetic energy of the object?</h3>

Kinetic energy is simply energy possessed by a body in motion.

Kinetic energy is expressed as;

Kinetic energy = 1/2 × m × v²

Where v is velocity and m is mass of the object,

Given the data in the question;

Mass of the object m = 328kg
Velocity of the object = 10m/s
Kinetic energy = ?

To determine the kinetic energy of the object, plug the given values into the formula above.

Kinetic energy = 1/2 × m × v²

Kinetic energy = 1/2 × 328kg × (10m/s)²

Kinetic energy = 1/2 × 328kg × 100m²/s²

Kinetic energy = 328kg × 50m²/s²

Kinetic energy = 16400kgm²/s²

Kinetic energy = 16400J

Therefore, the kinetic energy 16400 Joules.
