The charge on one mole of electrons = 96485 C = 1 Faraday
so if charge is 96485 C the moles of electrons are 1 = 6.023 X 10^23 electrons
if charge is 1 C the number of electrons = 6.023 X 10^23 / 96485
If charge is 50 micro C the number of electrons
= 6.023 X 10^23 X 50 X 10^-6 / 96485
= 3.12 X 10^14 electrons
Answer:
Los metaloides o semimetales son un tipo de elementos químicos que muestran un comportamiento intermedio entre los metales y los no metales, en cuanto a asuntos de ionización y propiedades de enlace. ... La lista de los metaloides abarca los siguientes elementos: Boro (B). Silicio (Si).
Explanation:
Answer:
The difference in electronegativity between fluorine (4.0) and hydrogen (2.1) is quite high, so the shared electrons spend much more time in the vicinity of the fluorine atom. As a result, fluorine carries a partial negative charge in this molecule, whereas hydrogen carries a partial positive charge
Explanation:
Answer:
a. True
Explanation:
Hello there!
In this case, as Grignard reagents are widely used in organic-synthesis procedures, since they are compelling nucleophiles able to react with electrophiles such as carbonyl compounds (aldehydes, ketones, esters, carbon dioxide, etc) and epoxides; they are involved in the addition of new C-C bonds to an starting carbon chain; therefore, this statement is a. True.
Best regards!
