Answer:

Label A - Radio waves

Label C - Infrared

Label D - Visible light

Label G- Gamma rays

Explanation:

  • Electromagnetic spectrum is an arrangement of electromagnetic waves in order of their varying frequencies and wavelengths,
  • Radiowaves have the highest wavelength and lowest frequency while the gamma rays have the lowest wavelength and the highest frequency.
  • In order of increasing wavelength and decreasing frequency the electromagnetic waves are; Gamma rays, X-rays, U.V light, Visible light, infrared waves, microwaves, and Radio waves.

if kept at a constant temperature, what is the concentration at 865s if the initial concentration was 0.0225M
Anestetic [448]

Answer:

[SO_2Cl_2]=0.0175M

Explanation:

Hello!

In this case, considering that the decomposition reaction of SO2Cl2 is first-order, we can write the rate law shown below:

r=-k[SO_2Cl_2]

We also consider that the integrated rate law has been already reported as:

[SO_2Cl_2]=[SO_2Cl_2]_0exp(-kt)

Thus, by plugging in the initial concentration, rate constant and elapsed time we obtain:

[SO_2Cl_2]=0.0225Mexp(-2.90x10^{-4}s^{-1}*865s)

[SO_2Cl_2]=0.0175M

Best regards!
