Answer: The molecules are $NH_3$ and $H_2SO_4$ .

Explanation:

Hydrogen bonding is defined as weak electrostatic force present between the hydrogen atom on one molecule with neighboring electro-negative atom of an other molecule. Usually oxygen nitrogen and fluorine atoms forms hydrogen bonding when present in a molecule of a compound.

From the given compounds , compound with any atom out of oxygen nitrogen and fluorine will form hydrogen bonding with the hydrogen atom present in a molecule adjacent to them.

The molecules are $NH_3$ and $H_2SO_4$ .

For the following reaction in aqueous solution, identify all those species that will be spectator ions. Select all that apply.

FromTheMoon [43]

The reaction is incorrect. The correct reaction is: Na₂SO₄ + Hg(NO₃)₂ → HgSO₄ + 2NaNO₃. The options are:

A. Hg₂SO₄

B. Na₂SO₄

C. Na⁺

D. NO₃⁻

E. SO₄⁻²

F. Hg₂(NO₃)₂

G. NaNO₃

H. Hg⁺²

Answer:

C, D, E, H

Explanation:

The ions are formed after dissociation of the compound in the solution. When they're negatively charged, they're called anions, when they're negatively charged, they're called cations. If the ion is presented on both sides of the reaction, it is called a spectator ion.

Thus, the reaction given:

Na₂SO₄ + Hg(NO₃)₂ → HgSO₄ + 2NaNO₃

So, let's do the dissociation.

Na₂SO₄ is formed by the ions Na⁺ and SO₄⁻²;

Hg(NO₃)₂ is formed by the ions Hg⁺² and NO₃⁻;

HgSO₄ is formed by the ions Hg⁺² and SO₄⁻²;

NaNO₃ is formed by the ions Na⁺ and NO₃⁻.

Thus, the spectator ions are Na⁺, SO₄⁻², Hg⁺², and NO₃⁻.

What are weak bonds that allow flexibility in an enzyme

34kurt

Enzymes are characterized to have weak bonds because their tertiary structure could easily bend and break because it will have to adjust to the shape of the substrate. It could be done via induced fitting or lock-and-key theory. These weak bonds are intermolecular forces like the London forces, electrostatic interactions and hydrogen bonding.
