The reaction of aqueous calcium bromide and aqueous lithium oxalate is represented by the balanced net ionic equation.

Ca2+(aq) + C2O42-(aq) → CaC2O4(s)

Give the balanced formula equation for the reaction. Include the states.

What's the problem? The problem tells you to start with CaBr2(aq) and Li2C2O4(aq) ==>

do we have to include the products that it yields, is it CaBr2Li2C2O4

The balanced formula equation for the reaction can be written as:

CaBr2(aq) + Li2C2O4(aq) → CaC2O4(s) + 2LiBr(aq)

To determine the balanced formula equation for the reaction, we need to consider the charges and the states of the reactants and products. Here's how we can approach it:

1. Write the formulas of the reactants:
Reactant 1: Calcium bromide (aqueous) - CaBr2 (aq)
Reactant 2: Lithium oxalate (aqueous) - Li2C2O4 (aq)

2. Determine the products:
Product: Calcium oxalate (solid) - CaC2O4 (s)

3. Write the balanced chemical equation by combining the reactants and products:
CaBr2 (aq) + Li2C2O4 (aq) → CaC2O4 (s)

That's the balanced formula equation for the reaction of aqueous calcium bromide and aqueous lithium oxalate.
