SOVA2 [1]2 years ago
4 0

Explanation:

The orbital diagram of an electron with eight electron is attached.  Since the 2p orbitals are filled using the maximum space available instead of pairing the electrons, this is in accord with Hund's rule.

When filling orbitals, you should put one electron in each box.  After all of the boxes in the orbital have one electron in each, you can then put the second electron into each of the boxes.

Nataly [62]
E = mc^2
E = 8.90 * 10^12 Joules
c = 3 * 10^8 m/s
m = ????

8.90 * 10^12 = m * (3 * 10^8)^2
8.90 * 10^12 = m * 9 * 10^16

A student analyzed an antacid tablet from a bottle containing 120 tablets purchased for $2.79. The mass of the tablet was 1.247
BaLLatris [955]

The cost of one antacid is 2.325 cents per tablet.

<u>Explanation:</u>

As per the question based on the student analysis we know that,

Total antacid tablets in a bottle = 120

Purchase Price of a bottle = $ 2.79

Cost of 1 antacid tablet =\frac{2.79}{120}  

As we know $1 = 100 cent

The cost of 1 antacid tablet = \frac{2.79}{120} × 100 cents = 2.325 cents/tablet .

Thus we came to know that it costs 2.325 cents/tablet .
