completing, balancing, and stating the physical state of all substances with total and net ionic equations
1)solid barium chloride reacts with sulfuric acid solution
2)neutralizes spilled oven cleaner (sodium hydroxide solution) with vinegar (acetic acid)
3)solid calcium in contact with solution of aluminium chloride
Ans. 1. BaCl2 in sulphur acid solution (aqueous solution)
Ionic: BaCl2(s) + H+(aq) + HSO4-(aq) -----------> BaSO4(s) + 2Cl-(aq) + 2 H+(aq)
Net: BaCl2(s) + H2SO4-(aq) -----------> BaSO4(s) + 2Cl-(aq) + 2 H+(aq)
Ans. 2. Na+(aq) + OH-(aq) + CH3COO-(aq) + H+(aq) -----------> CH3COO-(aq) + Na+(aq) + H2O(l)
NaOH + CH3COOH(aq) -----------> CH3COO-(aq) + Na+(aq) + H2O(l)
Ans. 3. #1. Ca(s) + 2H2O(l) ---------> Ca(OH)2(aq) + H2(g)
#2. Ca(OH)2(aq) + 2 Al(OH)3 ---------> Ca[Al(OH)4)2
Net: (#1+ #2) Ca(s) + 2H2O(l) + 2 Al(OH)3 ---------> Ca[Al(OH)4)2(aq) + H2(g)
