Which products would form if chlorine gas was bubbled through a solution of sodium bromide? Na and BrCl

Na(Cl)2 and Br2

Particle exchange energy though elastic collision , hope this .

A) the enthralling of formation for pure element in its standard state is always positivehope this : )

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
