Answer:

The metal atoms that plate your object come from out of the electrolyte, so if you want to copper plate something you need an electrolyte made from a solution of a copper salt, while for gold plating you need a gold-based electrolyte—and so on

This chemical reaction can also be written as

2C2H6+7O2-->4CO2+6H2O

This is a chemical reaction because reactants are converted into products. This is the combustion of ethane where ethane and oxygen have been converted into carbon dioxide and water

Predict the geometry around the central atom in SO2- A) trigonal pyramidal B) tetrahedral C) octahedral D) trigonal planar E) tr

liubo4ka [24]

<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

To calculate the hybridization of $SO_2$ , we use the equation:

$\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]$

where,

V = number of valence electrons present in central atom (S) = 6

N = number of monovalent atoms bonded to central atom = 0

C = charge of cation = 0

A = charge of anion = 0

Putting values in above equation, we get:

$\text{Number of electron pair}=\frac{1}{2}[6]=3$

The number of electron pair around the central metal atom are 3. This means that the hybridization will be $sp^2$ and the electronic geometry of the molecule will be trigonal planar.
