Red lights on a traffic light have a frequency of 4.3 X 10^15 Hz. What is the red light’s wavelength in meters? (Speed of light (c)= 3.00 X 10^8 m/s) A. 1.5 X 10^-49 meters
B. 7.0 X 10^-8 meters
C. 1.4 X 10^7 meters
D. 1.3 X 10^24 meters

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
