Explanation / Answer

1) A reaction between metal and dilute acid forming metal salt and hydrogen is called Acid- metal type reaction. Ni(s)+2HNO3-> Ni(NO3)2+ H2(g). 2KCl + Pb(NO3)2-> 2KNO3+ PbCl2. This reaction is called double replacement reaction. Double replacement reaction is the chemical reaction where two reactant ionic compound exchange ions to form two new product compounds with the same ions.
