Zinc iodide              ZnI₂            H₂O(ℓ),  I⁻(aq), Zn²⁺(aq),  

Nitrogen(I) oxide     N₂O           H₂O(ℓ),  N₂O(aq)

Sodium nitrite         NaNO₂      H₂O(ℓ),  Na⁺(aq), NO₂⁻(aq)

Glucose                   C₆H₁₂O₆    H₂O(ℓ),  C₆H₁₂O₆(aq)

Nickel(II) iodide       NiI₂            H₂O(ℓ),  I⁻(aq), Ni²⁺(aq)

  • Glucose and nitrogen(I) oxide are covalent compounds. They do not dissociate in solution.
  • The compounds containing metals are ionic. They produce ions in solution.
  • ZnI₂ and NiI₂ produce twice as many iodide ions as metal ions.

Balancing Chemical Equation<br> Na+Br2=NaBr
solniwko [45]

Answer:

2Na + Br2 = 2NaBr

Explanation:

In order to balance a chemical equation you make the make sure both sides have the same number of atoms on each side, you do this by multiplying on both sides as if it was a algebraic equation.

Na+ Br2 = NaBr

Na × 2 = Na2

Na × 2 = Na2

Br × 2 = Br2

2Na + Br2 = 2NaBr

Hope this helps.
