Crbr2(aq)+agno3(aq)→ express your answer as a chemical equation. enter noreaction if no reaction occurs. identify all of the phases in your answer.

First of all, CrBr2(aq) + AgNO3(aq) = AgBr(s) + Cr(NO3)2(aq) and balancing the chemical equation, CrBr2(aq) + 2 AgNO3(aq) = 2 AgBr(s) + Cr(NO3)2(aq)

The reaction between CrBr2 and AgNO is a double-replacement reaction such that the products would be AgBr and Cr(NO)2. If we are to express the reaction in an equation, this would become,

                     CrBr2(aq) + AgNO(aq) --> Cr(NO)2(aq) + AgBr(s)

If we are to balance out the equation,
 
                    CrBr2(aq) + 2AgNO(aq) --> Cr(NO)2(aq) + 2AgBr(s)

Answerthis solution will not form a precipitateexplanationsolubility equilbrium:         pbf₂(s)  ⇄ pb²⁺(aq) + 2 f⁻(aq)the solubility product expression is    (we exclude solids from the equilibrium expression).now suppose we have the trial ion product q, which we can define as    then, we can interpret  q as the product of the concentration of the ions that we have and ksp as the product of the ion concentrations that are needed to form a saturated solution.if q > ksp, then that implies that there will be a surplus of ions that exceed the amount that is required to form a saturated solution. a precipitate will then form (the precipitate continually  forms until the surplus ions are removed and q is decreased to ksp's value).if q = ksp, the saturated solution that forms is barely saturated and the precipitate will be minimal.if q < ksp, then the ion concentration will not be enough to form a saturated solution (so no precipitate).using our information, we calculate the trial ion product:     since q = 2.7  × 10⁻⁸ < ksp =  4  ×  10⁻⁸, a precipitate will not form.
