Actually when we burn metal salts, we cannot actually
really see distinct lines to appear because in reality, they are not really
visible to the human eye. There is only a certain range of wavelength of light that
our eyes can see.
To state in other way, some metal salts will give off light which has wavelengths that are outside of the visible region of the electromagnetic spectrum.<span> </span>
Answer: True!
Explanation: As electrons that are excited move between energy levels, they emit lots and lots of energy, in fact way more energy than ground state electrons (electrons that move within the same energy level) do, thus, making them more unstable.
Answer:
#1 is an organism
#2 is cell
#4 - Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go
POH = - log [ OH-]
pOH = - log [ 1 x 10⁻¹²]
