Which group or groups of atoms are the only atoms with f orbitals A. All atoms heavier than barium B. All atoms heavier than kry
Mashcka [7]

Answer:

All atoms heavier than barium

Explanation:

In the periodic table, elements are divided into blocks. We have the;

s- block elements

p- block elements

d- block elements

f- block elements

However, immediately after Barium, we now encounter elements that have f-orbitals. Barium possesses a fully filled d-orbital. Hence after it, we see elements with 4f and 5f orbitals called the Lanthanides and actinides. The elements following the lanthanide and actinide series possess completely filled f-orbitals as inner orbitals.

Hence elements heavier than barium all possess f-orbitals.

The whole cloves are broken up to help release the eugenol during distillation.
GREYUIT [131]

The statement is False.

No, whole cloves are not broken up to help release the eugenol during distillation.

Steam distillation:

  • Live steam is used in the co-distillation technique of steam distillation to separate mixture components.
  • It works well to extract essential oil constituents with high boiling points, such as those with boiling points of 200°C. However, the oil vapors themselves are warmer—around 100°C—helping to maintain the compounds' structural integrity.
  • It enables distillation to be carried out at lower temperatures than the boiling points of the constituent parts.
  • The high-boiling essential oils are vaporized by steam, and after passing through a cooling system, the hot vapors that were formed from them condense back into a liquid along with water.
  • A two-phase distillate, consisting of a water layer and an oil layer, is created because the oils are immiscible in water.

Given 16.2 grams of substance Y, if the substance absorbs 2722 joules of energy and the specific heat of the substance is 9.22 J
snow_tiger [21]
Since the substance absorbs heat, it is expected that the temperature will rise. The formula for the internal energy of a substance is given by the equation:

ΔU = mCpΔT

where:

ΔU = internal energy
m = mass of substance
Cp = specific heat capacity of substance
ΔT = change in temperature

ΔU = 2722 Joules = 16.2 grams (9.22 J/g-°C) (Tf - 26°C)

This gives a final temperature of Tf = 44.22 °C

Mass in grams of 6.023×1023 atom of Ca​
Mademuasel [1]

Answer:

\boxed {\boxed {\sf 40.08 \ grams}}

Explanation:

First, find the molar mass of calcium (Ca). This can be found on the Periodic Table.

  • 40.08 g/mol

Next, find the number of moles.

Avogadro's Number tells us the number of atoms in one mole.

  • It is 6.023*10²³

Therefore, there are 6.023*10²³ atoms in 1 mole.

We have 6.023*10²³ atoms of calcium, so it must also be 1 mole of calcium.

Finally, find the mass. Set up a proportion using the molar mass of calcium.

1 \ mol \ Ca * \frac{40.09 \ g}{1 \ mol \ Ca}

Multiply. The moles (mol Ca) will cancel.

1 * 40.08 \ g

40.08 \ g

There are <u>40.08 grams </u>in 6.023*10²³ atoms of calcium.
