Answer:
There are 4,46x10e-4 moles of CaCl2 (0,000446 mol)
Explanation:
A molar solution indicates the amount of moles of solute (in this case CaCl2) in 1 liter of solution (1000ml).
1000ml -----0,105 mol CaCl2
4, 25 ml----x=(4,25 ml x0,105 mol CaCl2)/1000ml= 4,46x10e-4 mol CaCl2
The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges.
The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds.
Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas
The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.
Answer:
one factor is the speed at which crystals are formed
<h3> explanation: </h3>
crystals that are formed near or on the surface tend to crystalize faster and therefore are usually smaller crystals deeper in the crust tend to crystalize slower and therefore are larger
