Answer:
Option C. 0.34 moles
Explanation:
Data obtained from the question include:
Molarity = 0.15M
Volume = 2.25L
Mole =
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 0.15 x 2.25
Mole = 0.34mole
The number of mole of AlCl3 present in the solution is 0.34mole.
Valence Electron is the outermost electrons, family(Alkali) 1 has 1 valence electrons and family(Alkaline) 2 has 2 valence electrons.
Hope this helps
Answer:
The correct answer is electrons.
Explanation:
The electrons refer to the negatively charged constituents, which are arranged in the orbits around the nucleus of an atom. It determines all the chemical and physical characteristics of an atom except the radioactivity and mass. It is a stable subatomic particle witnessed in all the atoms and functioning as the chief carrier of electricity in solids.
