The given question is incomplete. The complete question is:
Which molecule would diffuse faster 
, or 
,? Explain your reasoning.
Answer: will diffuse faster as it has low molecuklar weight.
Explanation:
From Graham's law of diffusion rates, the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.
or 
Molecular mass of is 64 g/mol and Molecular mass of is 80 g/mol
Thus as molecular mass of is less , it will diffuse faster.
In infrared spectroscopy, absorption of electromagnetic radiation results in transitions between <u>Vibrational </u>energy levels.

What does spectroscopy mean?</h3>
Definition of spectroscopy Spectrum analysis is the study and measurement of the spectrum that matter emits when it interacts with electromagnetic (EM) radiation. It is the investigation of how frequency or wavelength affects the relationship between matter and radiation.
The various forms of spectroscopy include the following:
- Acoustic resonance: A type of spectroscopy that primarily uses the ultrasonic and sonic ranges of sound. It is a popular, affordable approach for classifying and valuing materials.
- X-ray photoelectron: This technique makes use of the diffraction patterns that X-rays produce as they travel through crystalline materials. The nature of the crystal structure can be inferred from these patterns.
- You can use circular dichroism, a type of light absorption spectroscopy, to determine how differently a sample absorbs left- and right-circularly polarized light.
- It is appropriate for exploring the electronic structure of molecules and detecting the compounds present. Ultraviolet-Visible (UV/Vis) Spectroscopy. It aids in the recognition of peptide bonds, coenzymes, side chains of amino acids, and prosthetic groups.
- NMR Spectroscopy: This technique uses nuclear magnetic resonance to measure the magnetic fields surrounding the nuclei. Radio waves are used to excite atomic nuclei in a material.
- Spectroscopy of the infrared range of the electromagnetic spectrum is known as infrared spectroscopy. Longer wavelengths and lower frequencies are found in infrared photons, and in infrared spectroscopy, the idea of absorption spectroscopy is used.
- Raman spectroscopy is a method of spectroscopy used to examine low-frequency system modes such as rotational, vibrational, and other modes.

Using pH to determine [H+]
10^-pH= 10^-2.45 = 2.1 x 10^-3
<span>
Now,
Ka=[H=][A-]/[HA] </span>
<span>So,
(2.1 x 10^-3)^2/0.0136 - (2.1 x 10^-3) </span>
<span>Ka=2.5 x 10^4</span>
Explanation:
a) Both A and R are true and R is the correct
explanation of A.
Answer:
A simple microscope is one that uses a single lens for magnification, such as a magnifying glass while a compound microscope uses several lenses to enhance the magnification of an object. It uses a lens to enlarge an object through angular magnification alone, giving the viewer an erect enlarged virtual image.
