A coordination complex consists of a central atom or Jon, which usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligand or complexing agents

How many hybrid orbitals are found in CCl4?

Answers

CCl4

For central atom C

The formula to calculate hybridization is:

n= 1/2 [group no. central atom +no. of monovalent atoms attached to central metal atom (except oxygen) + magnitude of negative charge - magnitude of positive charge]

n= 1/2 [4 +4 + 0-0]

n= 1/2 [8)

The hybridization is sp3 and the electron geometry is tetrahedral

the answer is FOUR 4
hope this helps ;)

Calculate the number of moles 3.16 g of KMnO4 32.33 g of K2CrO4 100 g of KHCO3

Answers

The number of moles:
3.16g of $KMnO_(4)$
1 mole of $KMnO_(4)$ - 158g.
x moles of $KMnO_(4)$ - 3.16g.
$x=(1\ mole*3.16g)/(158g)=(3.16)/(158)=0.02\ mole$

The number of moles:
32.33g of $K_(2)CrO_(4)$
1 mole of $K_(2)CrO_(4)$ - 194g.
x moles of $K_(2)CrO_(4)$ - 32.33g.
$x=(1\ mole*32.33g)/(194g)=(32.33)/(194)=0.17\ mole$

The number of moles:
100g of $KHCO_(3)$
1 mole of $KHCO_(3)$ - 100.1g.
x moles of $KHCO_(3)$ - 100g.
$x=(1\ mole*100g)/(100.1g)=(100)/(100.1)=0.999\ mole$

Lewis acid is:

A. a substance that accepts electrons to form a covalent bond

What is a Lewis acid?

A Lewis acid is accordingly any substance, for example, the H+ particle, that can acknowledge a couple of nonbonding electrons. At the end of the day, a Lewis acid is an electron-pair acceptor.

Thus, option A is correct.
