Question

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.

Alycia Zemlak · Accepted 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)

Alycia Zemlak · Answer

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 grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)     calculation mass = moles   of ba   x molar   mass of ba   molar mass of ba from periodic table=   137.3 g/mol   use the   avogadro's law   constant   to   calculate the moles of barium   that   is     1 mole =   6.02   x 10^23 atoms                     ? moles = 2.3 x 10^23   atoms by cross   multiplication=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   molesmass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)explanation:
