Complete and balance the following molecular equation.
Al(OH)3(s)+HNO3(aq)→
And write the net ionic equation for it.
To complete and balance the molecular equation, we need to make sure that the number of atoms on each side of the equation is equal and that the charges are balanced.
The chemical formula for aluminum hydroxide is Al(OH)3, and for nitric acid is HNO3.
First, let's write the initial unbalanced equation:
Al(OH)3(s) + HNO3(aq) →
Now, let's balance the equation by following these steps:
1. Write the balanced chemical formula for each reactant and product:
Al(OH)3(s) + HNO3(aq) → Al(NO3)3(aq) + H2O(l)
2. Identify the number of atoms for each element on both sides of the equation:
Al: 1 on the left, 1 on the right
O: 3 on the left, 3 on the right
H: 3 on the left, 2 on the right
N: 1 on the left, 3 on the right
3. Balance the equation by adjusting the coefficients in front of each compound:
2Al(OH)3(s) + 6HNO3(aq) → 2Al(NO3)3(aq) + 6H2O(l)
Now, the equation is balanced.
Next, let's write the net ionic equation by removing the spectator ions (ions that appear on both sides and do not participate in the reaction):
The net ionic equation is:
2Al(OH)3(s) + 6H+(aq) + 6NO3-(aq) → 2Al3+(aq) + 6NO3-(aq) + 6H2O(l)
Simplifying it further, we get:
2Al(OH)3(s) + 6H+(aq) → 2Al3+(aq) + 6H2O(l)
The net ionic equation shows only the species that are actively involved in the reaction.
