Answer:

0.355 N of HF

Explanation:

The titration reaction of HF with KOH is:

HF + KOH → H₂O + KF

<em>Where 1 mole of HF reacts per mole of KOH</em>

<em />

Moles of KOH are:

0.0296L × (0.120 equivalents / L) = 3.552x10⁻³ equivalents of KOH = equivalents of HF.

As volume of the titrated solution was 10.0mL, normality of HF solution is:

3.552x10⁻³ equivalents of HF / 0.010L =<em> 0.355 N of HF</em>

What causes atoms to form covalent bonds?
tino4ka555 [31]

Sharing of valence electrons.

Explanation:

In a covalent bonds, there is sharing of the valence electrons used in bonding between the two combining species.

The atoms taking part do not have a wide electronegativity difference between them and so they share the valence electrons to complete their octet and ensure their stability.

  • For the formation of this bond type, each of the atom requires a odd or unpaired electrons.
  • Covalent bonds are formed between atoms having zero or very small electronegativity difference.
