Pb(s) + KNO3(aq) ----> No reaction
HNO3(aq) + Sr(OH)2(aq) ----> H2O + Sr(NO3)2
NO3 being Nitrate, and (OH)2 meaning 2 Oxygen and 2 Hydrogen atoms in the second problem. The second two in the products of the second problem is a subscript for NO3.
Are these correct? Thank you!
First one is correct.
Second one is correct for the products and the reaction but it isn't balanced.
