Answer:
Mg₃(PO₄)₂
Explanation:
Note: The phosphate ion is PO₄³⁻
3Mg⁺² + 2PO₄³⁻ => Mg₃(PO₄)₂
<span>The reason why it is easiest to assume the first step is slow is because that would be your rate determining step and would give you the rate law given in the problem. So you take the two compounds from the rate law given and put them as your two reactants in your first step:
NO2 + F2 ---> NO2F + F (all gases)
Your next step needs to make sense for your overall reaction. And you also need to have an intermediate which in this case will be F:
F + NO2 ---> NO2F (again all gases) This is the fast step.
Your intermediate cancels out to give you your overall equation:
2NO2 + F2 ---> 2NO2F (all gases)</span>

Yes, 50 pennies plus 50 pennies equals 100 pennies minus 50pennies equals 50 pennies.
Answer:
Gaps are produced in the light spectra that correspond to wavelengths of absorbed photons.
Explanation:
When electrons in atoms absorb energy, they move from a lower energy level to a higher energy level. With time, they revert to the their original energy state emitting a photon of light of appropriate wavelength.
The absorbed photons do not show up in the spectrum. They appear as dark lines in the spectrum. Hence, the absorption spectrum is the exact inverse of the emission spectrum. The dark lines in the spectrum indicates that the colors that ought to occupied those points there have been absorbed.
