1. Write the empirical and graphic formulas of nitric acid and aluminium
Gwar [14]

1. HNO₃ nitric acid

Al(NO₃)₃ aluminium nitrate

You may find the the attached picture the graphical representation of both compounds.

2. You may find bellow the full equations

Explanation:

1.  HNO₃ nitric acid, Al(NO₃)₃ aluminium nitrate

dissociation equation

HNO₃ (l) + H₂O (l) → NO₃⁻ (aq) + H₃O⁺ (aq)

Al(NO₃)₃ (s) + H₂O (l) → Al³⁺ (aq) + 3 NO₃⁻ (aq)

2. molecular equations

Al(OH)₃ (s) + NaOH (aq) →  NaAl(OH)₄ (s)

Ba(OH)₂ (aq) + NiCl₂ (aq) →​ BaCl₂ (aq) + Ni(OH)₂ (s)

ionic equations

Al(OH)₃ (s) + Na⁺ (aq) + OH⁻ (aq) →  NaAl(OH)₄ (s)

Ba²⁺ (aq) + 2 OH⁻ (aq) + Ni²⁺ (aq) + 2 Cl⁻ (aq) →​ Ba²⁺ (aq) + 2 Cl⁻ (aq) + Ni(OH)₂ (s)
