Question

A beaker of nitric acid is neutralized with calcium hydroxide. Write a balanced molecular equation for this reaction

Answer 1

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

hope this will help ya!!!
