Answer:
a) 21 bonds , and 4 bonds
b) bond angles , a < 109.5° , b ≈ 120° c < 109.5° d,e < 120° f ≈ 120° g ≈ 109.5°
c) 6 carbon atom are sp² hybridized
d) two carbon atoms are sp³ hybridized,
two oxygen atoms are sp³ hybridized
Nitrogen is not sp³ hybridized , it has sp² hybridization
e) vitamin B6 exhibit delocalized bonding, because the three double bond in ring are delocalized over 5 carbon atoms and one nitrogen atom , they are formed due to 6 p orbitals of 5 carbons and 1 Nitrogen atom. The bonding in vitamin B6 is similar to the Benzene.

Answer:
15.24 × 10²³ atoms
Explanation:
Given data:
Number of atoms of Na = ?
Number of moles of Na = 2.53 mol
Solution:
1 mole contain 6.022× 10²³ atoms.
2.53 mol × 6.022× 10²³ atoms / 1mol
15.24 × 10²³ atoms
The number 6.022 × 10²³ is called Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
I'd say that his comb has a static electricity charge. It can either be negative, or positive. Let's just say it's positive, and the water is negatively charged. This means that it will affect the water flow when the two charges meet. I hope this helps! ~Mia
Answer:
ide
in binary ionic compounds, you change the suffix of the nonmetal to ide. example: sodium chlorIDE
