Question

a4: (1) Balance the following reaction; (2) Wh bromide are mixed? Or in the other word, derive a net ionic reaction equation from the re at net ionic reaction occurs when aqueous solutions of potassium carbonate and ion from the reaction ???? FeBr3- + Fe2(CO3)3(s) + KBr 05: Two solutions (CaBr2 and Li,CO,) are mixed together to give the following reaction. (1) ls this a neutralization, or precipitation, or oxidation-reduction reaction? (2) balance the reaction; and (3) write a net ionic reaction equation. CaBT2 + Laco, ? Caco, (s) + LiBr balanced net ionic equation for the reaction between aqueous solutions of acetic acid and sodium hydroxide? Q6: What is the CH,CO,H(aq)+OH (aq)CHylaq)+Co, (oa)+Hlg) CH,CO H(aq)+ OH (aq)-> CH (aq)+CO-(g)+ H0 CH3CO2H(aq) + OH"(aq) CH3C02-(aq) + H2O CH,CO,H(aa)+2Na (aa)+20H (oq) CH,CO (a)+2Na (aq)+ HO

Explanation / Answer

Ans 4

K2CO3(aq) + FeBr3(aq) --> KBr(aq) + Fe2(CO3)3(s)

The balanced reaction is

3 K2CO3(aq) + 2 FeBr3(aq) --> 6KBr(aq) + Fe2(CO3)3(s)

Molecular ionic equation

6K+(aq) + 3CO3 2-(aq) + 2 Fe3+(aq) + 6Br-(aq) --> 6K+(aq) + 6Br-(aq) + Fe2(CO3)3(s)

Net ionic equation

3 CO32-(aq) + 2 Fe3+(aq) --> Fe2(CO3)3(s)

Spectator ions = K+ & Br-
