What's the balanced equation for nitric acid + aluminium oxide = aluminium nitrate + water

Al₂O₃ + 6HNO₃ → 2Al(NO₃)₃ + 3H₂O

Explanation:

      left side of arrow      right side of arrow

Al               2                             1

O               3                             1

H                1                             2

NO₃           1                              3

Al₂O₃ + 6HNO₃ → 2Al(NO₃)₃ + 3H₂O

now there are,

      left side of arrow      right side of arrow

Al               2                             2

O                3                             3

H                6                            6

NO₃            6                            6

you have to try and multiply different numbers and stop when you have equal molecule  on both sides of the arrow.
