How do properties of waves affect light and sound
Iteru [2.4K]

Answer:

Explanation:

Both light and sound can be described in terms of wave forms with physical characteristics like amplitude, wavelength, and timbre. Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies.

Write out the recipe and list all the ingredients (including the measures) of your favorite dish.
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.

Oxalic acid is a polyprotic acid. Write balanced chemical equations for the sequence of reactions that oxalic acid can undergo w
tiny-mole [99]

The chemical formula of oxalic is H_{2}C_{2}O_{4}

When oxalic acid reacts with water, first, oxalic acid removes one proton and results in the formation of mono acids.

After that, in second step, oxalic acid in aqueous solution removes another proton which shows it is a polyprotic acid.

The chemical equations are: (the reactions occurs in two steps due to presence to hydrogen atoms).

When one proton is removed:

H_{2}C_{2}O_{4} (aq)+H_{2}O (l)\rightarrow HC_{2}O_{4}^{-}(aq)+H_{3}O^{+}(aq)

When another proton is removed:

HC_{2}O_{4}^{-} (aq)+H_{2}O (l)\rightarrow C_{2}O_{4}^{2-}(aq)+H_{3}O^{+}(aq)

The dissociation of oxalic acid in water in shown in the image.
