Question

Answer 1

looks right to me

Answer 2

i observed the fume inside test tube when i added HCl into the solution... i mean after adding NaOH to Ammonium acetate why is that?

Answer 3

not sure without doing the reaction, but you might be generating more ammonia, which fumes out. you might be generating hydrogen gas, which now that I think about it seems more likely
