    Instead of just giving you the answer, I'll explain to you how to do it. Trust me after this you're gonna be like "Oh, that's easy!"

    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

    In order to balance this, you have to count each element where the elements in the reactants side and the product side should have equal number of molecules. The balanced reaction is as follows:

    2HNO3 + Ca (OH) 2 = Ca (NO3) 2 + 2H2O
