finlep [7]

Answer:

hypochlorite ion

Explanation:

The hypochlorous acid, HClO, is a weak acid with Ka = 1.36x10⁻³, when this acid is in solution with its conjugate base, ClO⁻ (From sodium hypochlorite, NaClO) a buffer is produced. When a strong acid as HCl is added, the reaction that occurs is:

HCl + ClO⁻ → HClO + Cl⁻.

Where more hypochlorous acid is produced.

That means, the HCl reacts with the hypochlorite ion present in solution

arsen [322]

The recipe for an omelet are:

<u>Ingredients</u>

  • 1 Egg
  • Salt and pepper ( 1 tablespoon )
  • Butter ( 1 tablespoon )

<u>Recipe:</u>

  • Turn on the heat and place a pan on it.
  • Add butter to the pan.
  • Crack the egg and whisk it properly.
  • Add the whisked omelet onto the pan and stir.
  • Add salt and pepper.

<h3>How to illustrate the information?</h3>

When we turn on the heat and place the pan, a heat transfer takes place and heat transfers from one body to another.

When we add butter to the pan, then the temperature of the pan was more than that of the butter.

Since the melting point of butter was less than the temperature of the pan, the the melting of butter takes place.

When we add the egg, the evaporation of the liquid present in the egg yolk and the egg white takes place.

These are the chemical reactions depicted.
