Shorter because the I-I bond in the I2 molecule is covalent whereas the bond between adjacent molecules is due to dispersion.
<h3>What is bond length?</h3>
Bond length typically falls between 0.1 and 0.2 nm. Covalent radius is the term used to describe the length of a connection formed between two comparable atoms. The order of the bond or the quantity of linked electrons between two atoms determines the bond length.
<h3>
What connection exists between the length and the strength of a bond?</h3>
The C-C bond in alkanes must be the longest since it is the weakest, and the C-C bond in alkynes must be the shortest because it appears to be the strongest, according to the data. We determined in the preceding section that the bond strength is inversely correlated to the bond length.
<h3>How can bond length be calculated in chemistry?</h3>
- The bond gets shorter as the atoms get smaller.
- The length of the bond decreases as bond multiplicity increases.
- The shorter the bond, the higher the effective nuclear charges of the bound atoms.

Answer:
4.97 X 10^13 ATOMS OF Zn
Explanation:
how many atoms of zinc are required to weigh 5.4 ng
a nano gram is 10^-9 grams
Zinc has an atomic mass of 65.39 gm/moles
there is an Avogadros number of atoms in a mole
65.39 GRAMS PER MOLE
65.39 g/(6.022 X 10^23)how many atoms of zinc are required to weigh 5.4 ng
GRAMS PER ATOM
1.086 GRAMS PER 1O^22 ATOMS
1 atom of Zn weighs 1.086 X 10^9 X 1O^-22 n grm=
1,086 X 10^-13 n gm
Y tines 1.086 X 10^-13 = 5.4 n gm
Y = 5.4/ (1.086 X 10^-13) =
4.97 X 10^13 ATOMS OF Zn
CHECK
(4.97 X 10^13 ) X 65.39 gm/(6.022 X 10^23) =
5.397 X 10^-9 =
5.4 n g
The standard temperature is 0c.
the standard pressure is 1atm.

Answer:
The balanced equations for those dissociations are:
Ba(OH)₂(aq) → Ba²⁺(aq) + 2OH⁻ (aq)
H₂SO₄ (aq) → 2H⁺(aq) + SO₄⁻²(aq)
Explanation:
As a strong base, the barium hidroxide gives OH⁻ to the solution
As a strong acid, the sulfuric acid gives H⁺ to the solution
Ba(OH)₂, is a strong base so the dissociation is complete.
H₂SO₄ is considerd a strong acid, but only the first deprotonation is strong.
The second proton that is released, has a weak dissociation.
H₂SO₄ (aq) → H⁺(aq) + HSO₄⁻(aq)
HSO₄⁻(aq) ⇄ H⁺ (aq) + SO₄⁻² (aq) Ka
