'...The mixture slowly crept up the test tube and over the rim fizzing. It overflowed in a matter of seconds, leaving half of its self behind in firm sticky bubles that clung to the edges and sprouted from the middle of the test tube...'

The balanced equation for the dissociation of water is: 2H2O (liquid) ⇌ 2H+ (aqueous) + O2- (aqueous)
The dissociation equation for potassium chromate (K2CrO4) in water is: K2CrO4(s) -> 2K+(aq) + CrO4^2-(aq).
The dissociation equation for sodium acetate (NaCH3COO) in water would be: NaCH3COO (s) -> Na+ (aq) + CH3COO- (aq)
The dissociation equation for mercury(II) bromide (HgBr2) in water is: HgBr2(s) -> Hg2+(aq) + 2Br-(aq)
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
The equation for the dissociation of water is: H2O ↔ H+ + OH-
The balanced equation for the dissociation of water is: 2H2O (liquid) ⇌ 2H+ (aqueous) + O2- (aqueous)
The dissociation equation for zinc fluoride (ZnF2) in water is: ZnF2 (s) → Zn2+ (aq) + 2F- (aq)
The dissociation equation for CaCl2 in water is: CaCl2 (s) → Ca2+ (aq) + 2Cl- (aq)
The dissociation equation for potassium chromate (K2CrO4) in water is: K2CrO4(s) -> 2K+(aq) + CrO4^2-(aq).
The dissociation equation for sodium acetate (NaCH3COO) in water would be: NaCH3COO (s) -> Na+ (aq) + CH3COO- (aq)
The dissociation equation for mercury(II) bromide (HgBr2) in water is: HgBr2(s) -> Hg2+(aq) + 2Br-(aq)
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
The equation is: NaCl----------Na++ Cl-
You get diluted vinegar. Most vinegar sold today is already diluted with water, so any dissociation of the acetic acid molecules has already occurred before you get it.
The dissociation equation for potassium chloride (KCl) in water is: KCl (s) → K+ (aq) + Cl- (aq) This equation shows that when KCl is dissolved in water, it dissociates into its constituent ions potassium (K+) and chloride (Cl-).
The dissociation equation for Pb(NO3)2 in water is: Pb(NO3)2(s) → Pb2+(aq) + 2NO3-(aq)
