We have to know which do not violet octet rule.
The central atom in SF₄ does not violate the octet rule. the central atom in CF₄ does not violate the octet rule.
As per octet rule, atoms can combine either by transfer of valence electrons from one atom to another or by sharing of valence electrons in order to have an octet in their valence shell.
The central atom S of SF₄ contains 8 electrons in the valence shell. Also, C atom of CF₄ contains 8 electrons in the valence shell.
ICl₄⁻ contains 9 electrons in the outermost shell.
Answer:
0.1
Explanation:
Using Henderson-Hasselbalch equation
pH = pKa + log ( base / acid )
pH= 9.0 , pKa = 10.0
9.0 = 10 + log ( base / acid )
9 - 10 = log ( base / acid )
10⁻¹ = ( base / acid )
( base / acid ) = 0.1
A simple epithelium has cells that form a single layer that are attached to the basement membrane. A stratified epithelium, on the other hand, consists of multiple layers of cells where only the basal layers are attached to the basement membrane.
Answer:
Plants take carbon dioxide out of the atmosphere, but they also have other effects, such as changing the amount of evaporation from the land surface. ... The plants absorb carbon dioxide for photosynthesis through the same pores (called stomata). But when carbon dioxide levels are high, the leaf pores shrink.
