Answer:
Explanation:
Sulfur has valence electron 6 and oxygen has 6*3 = 18 valence electrons. In this drawing, you'll see that sulfur violates the octet rule that is it has more than 8 electrons but it is legal since sulfur is in 3rd period, and elements that fall in 3rd period or more in periodic table can use their d orbitals and others to go beyond the normal "8" electrons in valence shell rule which is octet rule
All the formal charges are minimized...that is everything has formal charge of 0 in this structure which is always encouraged.

Following are the pair of elements that result in an ionic compound
Option A and B
<u>Explanation:</u>
- Ionic compounds are defined as the compound that consists of ions held by two atoms of differently charged ions.
- These compounds have a positive charge of ions called cations and a negatively charged element is anions.
- In the above options, we shall say that the atoms such as Ca and K both result in cations as they release an electron to become a positive ion.
- Also, Cl and S both result in anions as they attract more electron to form negative ions.
- These positive and negative ion together results in an ionic compound.
The initial concentration was 8.45M
Step 1: Given data
Initial concentration (C₁): ?
Initial volume (V₁): 635 mL = 0.845 L
Final concentration (C₂): 6.00 M
Final volume (V₂): 1.19 L
Step 2: Calculate the initial concentration
We have a concentrated NaCl solution and we want to prepare a diluted one. We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
C₁ = C₂ × V₂ / V₁
C₁ = 6.00 M × 1.19 L / 0.845 L
C₁ = 8.45 M
Thus, The initial concentration was 8.45M
