Answer:
- <em>Option D. temperature</em>
Explanation:
Indeed it is generally established that <em>temperature is a measure of the kinetic energy ot the particles</em>.
The <em>kinetic energy</em> of a particle is proportional to the product of the mass and the square of the speed. Mathematically, the kinetic energy, KE, is:
Where m is the mass and v the speed of the particle.
In a sample of matter, not all the particles have the same speed, hence not all the particles have the same kinetic energy.
The kinetic energy and the temperature are related by the Boltzman equation:
Where K is a constant (Boltzman constant) and T is the absolute temperature.
Therefore, as you can see from the last equation, <em>the temperaure is a measure of the averate kinetic energy of the particles in a sample of matter</em>.
This is, at a certain temperature, every substance has the same average kinetic energy.
Answer:
A. H3O+/OH−
Explanation:
A conjugate acid-base pair are a pair of molecules that differ in 1 H⁺
A. The conjugate pair of H₃O⁺ = H₂O not OH⁻
B. The conjugate pair of NH₄⁺ is NH₃
C. The conjugate pair of C₂H₃O₂⁻ is HC₂H₃O₂
D. The conjugate pair of H₂SO₃ is HSO₃⁻
That means right option, that is not a conjugate acid-base pair, is:
<h3>A. H3O+/OH−
</h3>
Answer:
shorter wavelength = alpha wave
Explanation:
Given that,
The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz.
We need to compare the wavelengths of these two waves.
For alpha wave,
For beta wave,
From the above calculations, we find that the wavelength of the alpha wave is shorter than the wavelength of the beta wave.
The answer is D. This is because liquids take up the shape of the container they are in, so it is never definite. Where as solids stay the same shape.
I think the charge is +2
Hope this helps
