Predict the prdeucts of the following acid/base and precipitation reactions and balance the equations.

Question

Remeber to indicate (s), (l) or (aq

Q1. HCI(aq) + Mg(OH)2(aq)---->

Q2. Pb(NO3)2(aq)+ Na2S (aq)--->

Q3. write the ionic equation for question 2.

Answer 1

1. acid + base = salt + water
2HCl + Mg(OH)2 ==> 2H2O + MgCl2
You add the phases.

2.
Pb(NO3)2 + Na2S ==> PbS(s) + 2NaNO3(aq)
You add the other phases.
3.
Pb^2+(aq) + S^2-(aq) ==> PbS(s)
