The fourth equation is correct:
Ca(OH)2 + 2 HNO3 → 2 H2O + Ca(NO3)2
Check atoms: Ca 1, H 4 (2 from Ca(OH)2 + 2 from 2 HNO3 → 4 in 2 H2O), N 2, O 8 on both sides.
Net ionic (acid–base) form: Ca(OH)2 + 2 H+ → Ca2+ + 2 H2O (or 2 OH− + 2 H+ → 2 H2O).
Ca(OH)2 + 2 HNO3 → 2 H2O + Ca(NO3)2
Check atoms: Ca 1, H 4 (2 from Ca(OH)2 + 2 from 2 HNO3 → 4 in 2 H2O), N 2, O 8 on both sides.
Net ionic (acid–base) form: Ca(OH)2 + 2 H+ → Ca2+ + 2 H2O (or 2 OH− + 2 H+ → 2 H2O).
