Due to electronegativity difference between H and F atom.
<h3>
What is the reason for the difference ?</h3>
- The bond length of HF is 92 pm. It is 16% shorter than the sum of the covalent radii of H (37 pm) and F (72 pm).
- The shorter of the bond length is due to the difference in electronegativity between H and F atom. The electronegativity of F is 4.0, whereas the electronegativity of H is 2.1.
- Greater the difference of electronegativity between the bonded atoms, shorter will be the bond length.
- As becomes smaller i.e. as we proceed from HF to HI, this effect becomes lessens and bond length will be more predictable.
Thus from the above conclusion we can say the difference in electronegativity between H and F atom this is the reason for shorter bond length of HF.

It has many different uses like being used to make the tube of a vacuum cleaner and also can be used to make oil in space crafts.
Answer:
Carbon Hydrogen
Explanation:
I believe it means carbon (C) to one atom of hydrogen (H).
Answer: True
Explanation: The answer is true because A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. … There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds.
Answer:
percentage of red skittles = 22%
percentage of skittles that are not green = 74%
Explanation:
total skittles = 50
yellow = 12
orange = 9
red = 11
green = 13
purple = 50-12-9-11-13
= 5
1) percentage of red skittles
2) percentage of skittles that are not green
