What is the hybridization of the positively charged carbon in (ch3)3c+?

Answer : The hybridization of the positively charged carbon is .

Explanation :  Formula used for Hybridization

Z=1/2{number of valence electrons of central atom + number of monovalent atom attached to it + negative charge - positive charge}

where, Z = Hybridization

Now for the compound

Number of valence electrons of central atom (C) = 4

Number of monovalent atom attached = 3

Number of negative charge = 0

Number of positive charge = 1

Now putting all the values in Z,

             Z =

                =  3

The corresponding Hybridization is i.e Trigonal planar .

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
