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)

The answer is -1, 0, 1.

For a given value of principal quantum number (n), the corresponding angular quantum number (l) value is equivalent to (n - 1). From this, you can get the set of values for mangetic quantum number m is:

m = -l, ..., 0, ..., l

So for n=2, l = 1, and m = -1, 0, 1
