Answer:
plzz can you explain in detail this Q
Answer:
Mitochondria brings food and water to your cells
Formal Charge is calculated as, Lewis structure is attached below,
Formal Charge = [# of valence electrons] - [electrons in lone pairs + 1/2 the number of bonding electrons]
# of valence electrons of Cl = 7
electrons in lone pairs = 4
number of bonding electrons = 6
Formal Charge = [7] - [4 + 6/2]
Formal Charge = [7] - [4 + 3]
Formal Charge = [7] - [7]
Formal Charge = 0
Result: Formal charge on Cl in ClF₃ is
zero.
I believe it would be the last one because you can use the molar mass of HCl to find the number of moles, then use Avogadro’s number to find the number of atoms
Hope this helps!

e) .00001503 significant figure-4
f) 60751.0 significant figure- 6.
zero after decimal are all significant . zero before decimal is significant only when it is preceded by a digit.All digits are significant.
