Aluminum hydroxide + nitric acid ➡ aluminum nitrate + water

m_a_m_a [10]

Answer:

Chemical equation:

HNO₃ + Al(OH)₃ → Al(NO₃)₃ + H₂O

Explanation:

Chemical equation:

HNO₃ + Al(OH)₃ → Al(NO₃)₃ + H₂O

Balanced chemical equation:

3HNO₃ + Al(OH)₃ → Al(NO₃)₃ + 3H₂O

Ionic equation:

3H⁺ + 3NO⁻₃(aq) + Al(OH)₃(s) → Al³⁺(aq) + 3NO₃⁻¹(aq) + 3H₂O(l)

Net ionic equation:

Al(OH)₃(s) + 3H⁺(aq) → Al³⁺(aq) + 3H₂O(l)

The NO⁻₃ are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.

Hydrogen bonding between polyamide chains plays an important role in determining the properties of a nylon such as nylon 6,6. Dr

Eduardwww [97]

Answer:

See figure 1

Explanation:

In the structure of nylon 6,6 we have amide groups. In this functional group, We have a nitrogen bond to hydrogen, so in this bond, we will have a dipole, due to the electronegativity difference. Nitrogen has more electronegativity than hydrogen, therefore a positive dipole would be generated in the hydrogen atom. Additionally, in the carbonyl group (C=O) due to the oxygen, we will have also a dipole, in this case, a negative dipole because the oxygen atom has more electronegativity (compare with carbon).

When we put two strings of nylon 6,6 the positive dipole will interact with the negative dipole and vice-versa and we will obtain the "hydrogen bonds".

See figure 1

I hope it helps!
