Ok, so here we go.
Ca(OH)2 + HNO3 --> Ca(NO3)2 + H2O
Start by examing Ca(OH)2:
1 Ca and 2 OH 1 Ca on left and 1 Ca on right side - Ca balanced
2 OH2 on left and 1 on right side - put a 2 in front of H2O
Ca(OH)2 + HNO3 --> Ca(NO3)2 + 2H2O
Now examine H: 1 H on left and 2 H on right side - H unbalanced
Place a 2 in front of HNO3
Ca(OH)2 + 2HNO3 --> Ca(NO3)2 + 2H2O
Now examine NO3:
2 NO3 on left and 2 on right side - NO3 is balanced
1 Ca(OH)2 + 2 HNO3 --> 1 Ca(NO3)2 + 2 H2O
