Br₂ is a completely non-polar molecule as it has two bromine atoms of equal electronegativities, which results in no dipole moment. CCl₄ is also a completely non-polar molecule. Although, there is a dipole moment for every C-Cl bond in the molecule. But since the structure of CCl₄ is tetrahedral, this results in every dipole cancelling out which provides an overall molecule with no dipole moment.
Since both molecules are non-polar with no net dipole moments, and there are no hydrogens capable of hydrogen-bonding, the only intermolecular forces between the two species are van der waals forces, more specifically London dispersion forces.
The London dispersion forces are instantaneous dipole moments created when the two molecules interact which causes a very weak attraction.
Answer:
This question needs more detail. it dosnt really make sense.
Explanation:
<span>Its concentration is half that of the cl? ion. CaCl2 has one Ca^2+ ion
and 2 Cl^- ions.It dissociates as follows
CaCl2 -> Ca^2+ + 2Cl^-
So we can see that when 1 CaCl2 dissolves we get 1 Ca2+ and 2Cl-
Therefore, the concentration of Ca^+2 will be 1/2 that of Cl^- since there are 2 Cl for every Ca.</span>
A chemical reaction is when two different types of chemicals combine and make a reaction
"The chemical reaction between yeast and sugar produces ethanol and carbon dioxide. The balanced chemical equation for this reaction is glucose/sugar (C6H12O6) in the presence of the yeast enzyme zymase reacts to produce 2C2H5OH (ethanol) +2CO2 (carbon dioxide). This is the ethanol fermentation process used to make beer, wine and bread. "
