Answer:
The correct option is;
A. Corresponding with orange light, is the wavelength that blue solutions absorb the most
Explanation:
The wavelength of 633 nm is the wavelength of red light emitted by the helium-neon laser also known as the He-Ne laser
According to absorption spectroscopy and the color wheel, a solution or drink sample that is efficient at absorbing light having a wavelength of 633 nm will appear blue, because, light at 633 nm is red and very close to orange which is the complementary color blue light.
333,000 Joules is the amount of energy (heat) in joules required to raise the temperature of 5 kg of iron from 50°C to 200°C.
Explanation:
Data given:
mass of iron 5 Kg or 5000
initial temperature = 50 degree centigrade
final temperature = 200 degrees centigrade
change in temperature (Δ T= 200 -50 degrees centigrade)
= 150 °C
cp (specific heat capacity of iron) = 0.444j/gram C
q (heat supplied) = ?
applying the formula,
q=mcΔT
putting the values in the equation:
q = 5000 X 0.444 X150
q = 333,000 Joules of energy.
The heat required 333,000 Joules of energy is required.
It will become an ion and no longer be neutral
