(H+)(OH-) = Kw
kw= 1 x10^-14
OH-= 1 x10 ^-11
(H+)= KW / OH-
concentration of H+ = (1x10^-14) /.(1 x 10 ^-11) = 1 x10 ^-3
Ph= -log (H+)
PH=-log ( 1 x 10 ^-3) = 3 therefore the solution is acidic since the PH less than 7
Answer:
Viscosity increases with stronger intermolecular forces
Step-by-step explanation:
<em>Viscosity</em> is the resistance of a liquid to flow.
A liquid can flow easily only if the molecules can move past each other with little resistance.
If there are strong intermolecular attractive forces among molecules, it is more difficult for them to move past each other.
For example, the molecules in molasses have strong attractive forces, so it is quite viscous.
Answer:
An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms. ... Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals.

<span>The number of lone electron pairs on the central atom of molecule having a linear molecular geometry such as CIF2- is three (3). In studying chemistry, linear molecular geometry describes the geometry around a central atom bind to two other atoms or ligands placed to a bond-angle of 180 degrees.</span>
