You would get 15 Fe because you can multiply the reactants by eachother to get the fe.
Mark as braliest please.
Hope this helps!
Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances.
Zinc is oxidized because it starts as a metal with an oxidation state of zero and ends up as an atom bound to oxygen. Oxygen has two bonds, so the oxidation state of Zinc would be 2. The Mercury is therefore reduced because it undergoes the opposite process. This is a REDOX reaction, and the two half-reactions are:
Zn -> Zn(+2) + 2e(-)
Hg(+2) + 2e(-) -> Hg
The answer to your question is C. I hope that this is the answer that you were looking for and it has helped you.
Answer:
The purpose or objective of the electromagnetic spectrum experiment the purpose is to figure out what elements are in the planets’ and the moons’ atmospheres by looking at their absorption spectrums
Explanation:
What is electromagnetic spectrum?
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10^25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high frequency (short wavelength) end.
The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications.
The limit for long wavelengths is the size of the universe itself.
Hello.
The result is the formation of ordinary table salt, sodium chloride and an equimolar amount of water. This reaction also gives off significant heat that could conceivably cause the reaction mixture to explosively boil.
This is the reaction:
