Answer:
polar covalent
Explanation:
The structure has a Sulfur atom in the middle with 6 Fluorine atoms surrounding this structure. Each fluorine atom has 3 unshared pairs to achieve the octet rule. In addition, this bond is polar covalent.
Answer:
it is calcium and bromine
Explanation:
this is because they are both ionic compounds
Answer:
A
Explanation:
the baking soda and vinegar were products of a chemical reaction
Answer:
Explanation:
1. Write the skeleton equation for the half-reaction
NO₃⁻ ⟶ N₂O
2. Balance all atoms other than H and O
2NO₃⁻ ⟶ N₂O
3. Balance O by adding H₂O molecules to the deficient side.
2NO₃⁻ ⟶ N₂O + 5H₂O
4. Balance H by adding H⁺ ions to the deficient side.
2NO₃⁻ + 10H⁺ ⟶ N₂O + 5H₂O
5. Balance charge by adding electrons to the deficient side.
2NO₃⁻ + 10H⁺ + 8e⁻ ⟶ N₂O + 5H₂O
The amount of charge required to reduce 2 mol of NO₃⁻ is 8 F
