Answer:
electrons on the the outer most shell of an element
Answer:
4.8× 10²³ atoms
Explanation:
Given data:
Number of moles of San element = 0.796 mol
Number of atoms present = ?
Solution:
Avogadro number:
The given problem will solve by using 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.
1 mole = 6.022 × 10²³ atoms
0.796 mol × 6.022 × 10²³ atoms / 1mol
4.8× 10²³ atoms
Answer:
decreases a bit then stays constant
Explanation:
Answer:
Explanation:
Hello,
In this case, considering that A's initial concentration is 4.0mol/dm³, considering the equilibrium conversion, one obtains for the equilibrium:
Thus, the equilibrium constant turns out:
