Question

Write a balanced net ionic equation for each of the following solution reactions....Given Equations => Zn(NO3)2(aq) + 2 NaOH(aq) ? Zn(OH)2(s) + 2 NaNO3(aq) & HNO3(aq) + KHCO3(aq) ? KNO3(aq) + H2O(l) + CO2(g)

Explanation / Answer

first molecular 2NaOH(aq) & 1 Zn(NO3)2(aq) --> Zn(OH)2(s) & 2 NaNO3(aq) dissociation equation 2Na+(aq) & 2(OH)-(aq) & 1 Zn+2(aq) & 2(NO3)-(aq) --> Zn(OH)2(s) & 2 Na+(aq) & 2 (NO3)-(aq) net Zn+2(aq) & 2(OH)-(aq) --> Zn(OH)2(s) ------------------------- second molecular 2 NaOH(aq) & Zn(OH)2(s) --> Na2[Zn(OH)4]-2(aq) second dissociation equation 2Na+(aq) & 2(OH)-(aq) & Zn(OH)2(s) --> 2Na+(aq) & [Zn(OH)4]-2(aq) second net 2(OH)-(aq) & Zn(OH)2(s) --> [Zn(OH)4]-2(aq) p.s. the combined overall molecular is 4 NaOH(aq) & Zn(NO3)2(aq) --> Na2[Zn(OH)4]-2(aq) & 2 NaNO3(ag) the combined overall net would be 4(OH)-(aq) & Zn+2(aq) --> [Zn(OH)4]-2 (aq) 2)HNO3 (aq) + KHCO3 (aq) -----> KNO3 (aq) + H2O (l) + CO2 (g) Total ionic equation: H+ (aq) + NO31- (aq) + K+ (aq) + HCO31- (aq) -----> K+ (aq) + NO31- (aq) + H2O (l) + CO2 (g) Net ionic equation: H+ (aq) + HCO31- (aq) -----> H2O (l) + CO2 (g) ------------------------- Molecular: 3H2S (aq) + 2FeBr3 (aq) ------> Fe2S3 (s) + 6HBr (aq) H2S is a very weak acid and doesn't ionize much in water. Total ionic: 3H2S (aq) + 2Fe3+ (aq) + 6Br- (aq) ------> Fe2S3 (s) + 6H+ (aq) + 6Br- (aq) Net ionic: 3H2S (aq) + 2Fe3+ (aq) -----> Fe2S3 (s) + 6H+ (aq)
