2Al + 3Cl2 → 2AICI
Chemical reaction

Correction: You’re reaction balancing is correct but there should be AlCl3 at the end of your equation.

Hope this can help.

Yes it would be a physical change.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
