the total translational kinetic energy of 1.0 mole of diatomic oxygen at 50 ∘c is:
A mole of diatomic oxygen has a total translational kinetic energy of 4000J at 50 °C.
What is diatomic oxygen?The diatomic molecule known as molecular oxygen is made up of two oxygen atoms that are covalently connected to one another (O2). Molecular oxygen is essential for life because it is required for breathing by such a wide variety of species. Combustion of fossil fuels also requires it. We refer to the elements as diatomic because the atoms are found in pairs. H2, N2, O2, F2, Cl2, Br, and I2 are the chemical formulas for these substances. The periodic chart makes it simple to locate the diatomic elements. Along with O and N, they contain the halogens (F, Cl, Br, and I).
Why are diatomic elements special and what benefits of diatomic oxygen are?A molecule made up of two of the same atom is referred to as a diatomic element. Diatomic is a compound word made up of the letters "di" for two & "atomic" for atom. With only one atom, a monatomic element can remain stable. Because they can adhere to the octet rule in this paired form, these diatomic elements are the most stable in it.
The advantages are:
• eliminating viruses (ozone and hydrogen peroxide)
• enhancing the bloodstream's ability to carry oxygen to the body's tissues.
• quickening petrochemicals' decomposition.
Briefing:If the speed of a diatomic hydrogen molecule is 200m/s
Therefore:
50∘C=200m/s
Then the total translational kinetic energy:
1.0mol=50∘C
So the calculation is:
Transactional kinetic energy =2000/50
=40
1.0mol=100J
=40*100

write the chemical formula for the conjugate acid of the aniline, c6h7n. (enter the elements in the order: c, h, n, o.)
The chemical formula for the conjugate acid of the aniline: Phenylammonium ion (C₆H₅NH₃⁺).
What is conjugate acid?Conjugation, also known as a verbal paradigm, derives from the Latin meaning "link together" and relates to the inflection of verbs for the person, number, tense, and mood.
A conjugate acid has one extra H atom and one more (+) ve charge than the base from which it was created. When an acid contributes a proton to a base, conjugate acid is created. A conjugate base has one fewer H atom and one more (-) ve charge than the acid from which it was produced.

The initial temperature of the water and copper is 22.51°C.
Mass of ice m = 14 g
We know, 1g = 0.001 kg
So, m= (14 x 0.001)kg = 0.014kg
Mass of water ml = 300g = (300 x 0.001)kg = 0.3kg
Mass of copper calorimeter m₂ = 200g = (200 × 0.001) kg = 0.21 kg
Specific heat of water s₁ = 4186 [tex]\frac{J}{kg . C}[/tex]
Specific heat of ice s₂ = 2100 [tex]\frac{J}{kg.C}[/tex]
Specific heat of copper s₃ = 387 [tex]\frac{J}{kg.C}[/tex]
Latent heat of fusion of water L = 3.33 x 10⁵ [tex]\frac{J}{kg}[/tex]
Initial temperature of ice T₁ = - 10°C
Initial temperature of water copper is T₂
Final temperature of the system is T = 18 °C
From equilibrium in heat
Heat gain by ice to become 0°C of ice +0°C of ice become 0 °C of water + 0°C of water become 18°C of water = heat loss by copper and water
ms₂ (0°-(-10°)) + mL + ms₁ (T -0°) = m₁s₁ (T₂-18°) + m₂s₃ (T2 - 18°)
∴ 0.014 × 2100 × 10 + 0.014 × 3.33 × 10⁵+ 0.014 × 4186 × 18 = 0.3 × 4186 × (T₂- 18 ) + 0.2 × 387 × ( T₂ -18 )
∴ 6010.87 = 1333.2(T₂ - 18)
∴ T₂ - 18 = 6010.87 / 1333.2 = 4.51
∴ T₂ = ( 18 + 4.51 )
∴ T₂ = 22.51° C
So, the initial temperature of the water and copper is 22.51°C.

The better the photon's frequency, the better its strength. Equivalently, the longer the photon's wavelength, the decrease its strength.You have to have observed that the because the frequency increases, the wavelength decreases.
The identical dating exists with one-of-a-kind colored mild waves. You have to be aware the identical connection among the frequency and the wavelength. The frequency of a wave is inversely proportional to its wavelength. That method that waves with a excessive frequency have a quick wavelength, whilst waves with a low frequency have an extended wavelength. Light waves have very, very quick wavelengths.

All those statements pertain to 3-butyl-4-pentene.
At room temperature, the chemical benzene is a colorless or pale yellow liquid. It smells pleasant and is quite combustible. Benzene swiftly disappears into the atmosphere. Its vapor can descend into low-lying locations since it is heavier than air. Benzene is classified as "carcinogenic to humans" by the IARC due to substantial proof that it causes acute myeloid leukemia (AML).
What is the purpose of benzene?A common industrial chemical is benzene. Crude oil contains benzene, which is also a main component of gasoline. Plastics, resins, synthetic fibers, rubber lubricants, dyes, detergents, pharmaceuticals, and pesticides are all made with it. Volcanoes and forest fires naturally produce benzoene.
