Merits of modern periodic table?​

Chemistry
1 answer:
ANEK [815]3 years ago
6 0

Answer:

<h3>Merits of modern periodic table:</h3>
  • The wrong position of some elements like argon, potassium, cobalt and nickel due to atomic weights have been solved by arranging the elements in the order of increasing atomic number without changing their own places.
  • The isotopes of some element have the same atomic numbers. Therefore, they find the same position in periodic table.
  • It separates metals from non-metals.
  • The groups of the table are divided into sub groups A and B due to their dissimilar properties which make the study of elements specific and easier.
  • The representative and transition elements have been separated.

Hope this helps...

A photon has 8.0 × 10–15 J of energy. Planck’s constant is 6.63 × 10–34 J•s. What is the frequency of the photon
german
The formula is:
frequency * h (Planck's constant) = Energy
So, to find frequency you need just divide energy by the constant:
frequency = (8 * 10^-15 J) / (6.63 * 10^-34 J*s) = 1.2 * 10^19 1/s or 1.2 * 10^19 Hz

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.
