Answer :
The steps involved in the lewis-dot structure of 
are :
- First we have to determine the total number of valence electron in .
Number of valence electrons in S = 6
Number of valence electrons in two F atom = 2(7) = 14
Total number of valence electrons = 6 + 14 = 20 electrons
- Placing a bonding pair of electrons between the atoms to form the chemical bonds.
Electrons used in bonding = 4
- The remaining electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the Lewis dot structure.
Electrons used as a lone pair = 20 - 4 = 16
The image is shown below.
It would be: 1 * 2 + 16 = 2 + 16 = 18
In short, Your Answer would be Option B
Hope this helps!
The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.
Option D
<h3>Chemical Reactions</h3>
Generally,the experiment shows that glass B temperature is higher than glass temperature A and this is given that observation that the solute dissolves faster in glass B than glass A.
Therefore,The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.

Answer: a
Explanation:
scientific notation is about how many places passed the decimial place you are moving. therefor in order to get 1,550,000,000 you would move the decimial from 1.55 over nine times to the right
