Solution
I am solving the first question as per Chegg guidelines, post multiple question to get the
remaining answers
Q1)
a) NaCl(aq) + AgNO3(aq) ----------- NaNO3(aq) + AgCl(s)
The AgCl is the milky white precipitate
b) 2Al(s) + 6HCl(aq) ---------- 2AlCl3(aq) + 3H2(g)
Bubble formation is due to the formation of H2 gas
