Answer:
Explanation:
check the attachment for the propose neutral structure for each compound that is consistent with the data.
This
electronic transition would result in the emission of a photon with the highest
energy:
4p
– 2s
<span>This
can be the same with the emission of 4f to 2s which would emit energy in the
visible region. The energy in the visible region would emit more energy than in
the infrared region which makes this emission to have the highest energy.</span>
Answer: Think of each polar bond in a molecule as a little arrow pointing from positive to negative. So, the geometry of the molecule determines the direction that the bond dipole vectors point. The polarity of the molecule results from adding up all these individual bond dipoles.
Answer:
278 mL x 0.038 M = 10,564 mmol.
Using the molair mass of Fe2(SO4)3 to convert mmol to grams:
10,564 mmol / 1000 x 399,88 g/mol = 4,22 g Fe2(SO4)3.
They are not chemicall combined, in order for something to be an element it has to be chemically combined. salsa and trail mix are mixtures, also mixtures can be easily picked apart, like you can seperate the pretzels and the m&ms
