It should have 10 electrons
Explanation:
The similarities between chemical and physical changes include change in state of matter and both process involve change in energy.
Chemical changes of a substance results in the formation of entirely new substances. These changes are not reversible.
Physical changes results in the change of the state of the substance which can be reversed.
However, both chemical and physical changes results in change of state of matter and both process results in change in energy.
Thus, we can conclude that the similarities between chemical and physical changes include change in state of matter and both process involve change in energy.
(it's alre answered but here it again 'NOTE: not my answer')
Yes..... I think.........
Answer:
2.11 ×10²⁴ atoms
Explanation:
Given data:
Number of moles of NaCl = 3.5 mol
Number of atoms = ?
Solution:
It is known that 1 mole contain 6.022×10²³ atoms. The number 6.022×10²³ is called Avogadro number.
3.5 mol ×6.022×10²³ atoms / 1 mol
21.1 ×10²³ atoms
2.11 ×10²⁴ atoms
