What will come in place of p and q, respectively, in the given double displacement reaction? Ag-p + NaCl → Ag-q + NaNO3

In the given double displacement reaction, Ag and Na ions exchange partners. Initially, Cl is with Na, so after the reaction, it pairs with Ag. Similarly, NO3 is initially with Ag, so after the reaction, it pairs with Na. The correct balanced equation is: AgNO3 + NaCl → AgCl + NaNO3. Thus, p is NO3 and q is Cl.
