Question

Write the balanced net ionic equation for the reaction that occur in the following case. Cr2(SO4)3(aq)+(NH4)2CO3(aq)→

Answer 1

its double displacement reaction :) now can u write

Answer 2

Molecular Equation: Cr2(SO4)3(aq) + (NH4)2CO3(aq) --- 2Cr(CO3)3(s) + 2NH4SO4 (aq) (It's not balancing yet. So we have to make it balanced!)

Balanced equation: 2Cr2(SO4)3(aq) + 3(NH4)2CO3(aq) --- 4Cr(CO3)3(s) + 6NH4SO4(aq)

Ionic Equation: 4Cr ^3+ (aq) + 6SO4^2- (aq) + 6NH4^1+(aq) + 3CO2^2- (aq) ----
4Cr(CO3)3(s) + 6NH4(aq) + 6SO4(aq)
*(6SO4 (aq) and 6NH4(aq) both sides you cancel it to get Net Ionic Equation)*

Net Ionic Equation: 4Cr^3+(aq) + 6SO4^2+(aq) ------ 4Cr(CO3)3(s)

I hope this is helping you.
Thank you!
*^3+ and ^2- means the power of each element*
