Answer:

- the electromagnetic spectrum is the range of electromagnetic radiation, organized by how much energy the radiation carries. there is an opposite relationship between wavelength, frequency, and energy. as the wavelength of a wave increases, the frequency and energy decrease, and vice versa.

- the order from longest wavelength (lowest energy) to shortest wavelength (highest energy) is as follows: radio waves, microwaves, infrared waves, visible light waves, ultraviolet waves, x-rays and gamma rays.

Explanation:

hope this helps!

What is the poH of a<br> 4.8 x 10-10 M H+ solution?
stiks02 [169]

Answer: pOH = 4.68

Explanation:

pOH = 14 - pH

pH = - Log [H+]

= - Log [4.8 x 10^-10]

= -(-9.32)

pH =+9.32

Therefore, pOH= 14 - 9.32

= 4.68

Which set of coefficients will balance this chemical equation?
Montano1993 [528]

Answer:

Option B is correct = 1,3

Explanation:

Chemical equation:

C₂H₄ + O₂     →    CO₂ + H₂O

Balanced chemical equation:

C₂H₄ + 3O₂     →    2CO₂ + 2H₂O

Step 1:

Left side                      Right side

C = 2                           C = 1

H = 4                           O = 3

O = 2                           H = 2

Step 2:

C₂H₄ + O₂     →    2CO₂ + H₂O

Left side                      Right side

C = 2                           C = 2

H = 4                           O = 5

O = 2                           H = 2

Step 3:

C₂H₄ + O₂     →    2CO₂ + 2H₂O

Left side                      Right side

C = 2                           C = 2

H = 4                           O = 6

O = 2                           H = 4

Step 4:

C₂H₄ + 3O₂     →    2CO₂ + 2H₂O

Left side                      Right side

C = 2                           C = 2

H = 4                           O = 6

O = 6                           H = 4
