Balancing Chemical Equations

To balance the chemical equations provided, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here are the balanced equations for the reactions you provided:

1) Zn(OH)2 + 2HNO3 → Zn(NO3)2 + 2H2O 2) Ba(NO3)2 + K2SO4 → BaSO4 + 2KNO3 3) 2Na2SiO3 + 3CaCl2 → 6NaCl + Ca3SiO5 4) CaO + 2HNO3 → Ca(NO3)2 + H2O 5) 3Zn(OH)2 + 2H3PO4 → Zn3(PO4)2 + 6H2O 6) 2Al + 3H2SO4 → Al2(SO4)3 + 3H2 7) FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl 8) 3Ca3(PO4)2 + 2H2SO4 → 3CaSO4 + 2H3PO4 9) 2Fe(OH)3 → Fe2O3 + 3H2O

Please note that the coefficients in front of each compound represent the number of molecules or formula units needed to balance the equation.
