Answer:
5.5 moles of given substance.
Explanation:
The given problem can be solved by using the Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
Solution:
3.311 ×10²⁵ / 6.022 × 10²³ = moles
5.5 moles of given substance.
Answer: The correct answer is absorbed.
Explanation:
Bond formation is a type of exothermic process. In these reactions when two atoms come close to each other, energy is released in this process.
On the other hand, in the breaking of bond, energy is required because the atoms are to be separated from each other. This is a type of endothermic process. So, the energy must be absorbed.
Hence, the correct answer is absorbed.
