Which of the following are found within the electromagnetic spectrum? Check all that apply. sound waves visible light X rays ult
1 answer:
Answer:
Visible light
X rays
ultraviolet radiation
gamma rays
microwave radiation
Explanation:
Electromagnetic waves consist of oscillating electric and magnetic fields which vibrate in a direction perpendicular to the direction of motion of the wave (transverse wave). Electromagnetic waves have all same speed in a vacuum (, known as speed of light) and are classified into 7 different types according to their frequency and wavelength. This classification is called electromagnetic spectrum.
From lowest to highest wavelength, the 7 types are:
Gamma rays
X-rays
Ultraviolet radiation
Visible light
Infrared radiation
Microwaves
Radio waves
Sound waves, on the contrary, do not belong to the electromagnetic spectrum, since they are another type of wave called mechanical waves (which consist of vibrations of the particles in a medium).

Answer:
a) CI^- ⇒ CI2 + 2e^-
b) 4.2 * 10^9 amperes
c) 1.4 * 10^10 watts
Explanation:
Given data:
Annual production of C12 = 45 millions tons per year
Typical plant operational percentage = 90%
Operating voltage of a cell = 3.4 v
A) Half-cell reaction for oxidation chloride to form chlorine
CI^- ⇒ CI2 + 2e^-
B) Calculate the total current worldwide needed to generate the global supply of CI 2
Total current = =
= 4.2 * 10^9 amperes
Q = charge , t = time
C ) Calculate electrical power need to produce global supply of chlorine using electrolysis
P = V*I
= 3.4 * 4.2 * 10^9
= 1.4 * 10^10 watts
