b. all six of the carbon–carbon bonds have the same length.
c. the carbon–carbon bond lengths are intermediate between those for single and double bonds.
d. the entire benzene molecule is planar.
e. the valence bond description involves sp2 hybridization at each carbon atom.

trigonal pyramidal

tetrahedral

trigonal planar

bent

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
