1. Balance the following reactions:
a. \(BaCl_2\) + \(H_2SO_4\) → \(BaSO_4\) + \(HCl\)
b. \(Ca(OH)_2\) + \(HNO_3\) → \(Ca(NO_3)_2\) + \(H_2O\)
c. \(Pb(NO_3)_2\) → \(PbO\) + \(NO_2\) + \(O_2\)
d. \(MnO_2\) + \(HCl\) → \(MnCl_2\) + \(Cl_2\) + \(H_2O\)
a. \(BaCl_2\) + \(H_2SO_4\) → \(BaSO_4\) + \(HCl\)
b. \(Ca(OH)_2\) + \(HNO_3\) → \(Ca(NO_3)_2\) + \(H_2O\)
c. \(Pb(NO_3)_2\) → \(PbO\) + \(NO_2\) + \(O_2\)
d. \(MnO_2\) + \(HCl\) → \(MnCl_2\) + \(Cl_2\) + \(H_2O\)
