Write net ionic equations for the following molecular equations. HBr is a strong electrolyte. (Include states-of-matter under SATP conditions in your answer. Use the lowest possible coefficients.)
(a) HBr(aq) + NH3(aq) → NH4Br(aq)
(b) 2 HBr(aq) + Ba(OH)2(aq) → 2 H2O(l) + BaBr2(aq)
(c) Pb(NO3)2(aq) + 2 NaBr(aq) → PbBr2(s) + 2 NaNO3(aq)
(d) MgCO3(s) + H2SO4(aq) → MgSO4(aq) + H2O(l) + CO2(g)
