Answer:
The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Think of the octet rule. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .
Answer:
I am pretty sure the answer is B. Hope this helps
Explanation:
The answer is A.
We know the formula for molarity :
<u>Molarity = Number of moles ÷ Volume</u>
<u />
Let's assume there are 0.6 moles of NaCl in 1 liter of ocean water.
Then, mass of salt is :
- Mass of one mole salt × 0.6
- 58.5 × 0.6
- 35 grams
