Question

1) Write an equation for the reaction HCl(aq) + Na2CO3 (s)-------->? (Note: In this reaction the products ust have H, Cl, Na, and O atoms in some new combinations, but no other elements can be present.)

2) Write an equation for the following reaction (note the similarity to the equation aboe): HCl(aq) + Na2SO3(s)---->?

3) Write an equation for the reaction: HCl(aq)+ ZnS(s)----->

4)Write an equation for the reaction Pb(NO3)2(aq)+ HCl(aq)------->?

5)Write an equation for the reaction BaCl2(aq)+ K2CrO4 (aq)----->?

6)Write an equation for the reacation (NH4)2CO3(aq)+ BaCl2(aq)----->?

Explanation / Answer

Na2CO3(s) + HCl(aq) = NaCl(aq) + H2O(l) + CO2(g)

2.)2HCl(aq) + Na2SO3(aq) -> 2NaCl(aq) + H2O(l) + SO2(g)

3.)ZnS(aq) + 2HCl(aq) --> ZnCl2(aq) + 2H2S(g)

4.)Pb(NO3)2(aq) + 2HCl(aq) --> PbCl2(s) + 2HNO3(aq)

5,)BaCl2(aq) + K2CrO4(aq) -> BaCrO4(s) + 2KCl(aq)

6.)(NH4)2CO3(aq) + BaCl2(aq) -> BaCO3(s) + 2NH4Cl(aq)
