Question: What does it mean if an element is isoelectronic?
Answer: Isoelectronic is a term to describe a group of atoms or ions having the same number of electrons
Explanation: they are both the same because they bot have the same number of protons in each atom and they both will have the same always not diffrent its gonna have the same number

Answer:
HgSO₄
Explanation:
% => g => moles => ratio => reduce => empirical ratio
%Hg = 67.6% => 67.6g/201g/mol = 0.34mol
%S = 10.8% => 10.8g/32g/mol = 0.34mol
%O = 21.6% => 21.6g/16g/mol = 1.35mol
Hg:S:O => 0.34:0.34:1.35
Reduce to whole number ratio by dividing by the smaller mole value...
Hg:S:O => 0.34/.34:0.34/.34:1.35/.34 => Empirical Ratio = 1:1:4
∴ Empirical Formula is HgSO₄
Answer:
- The condensation reaction that forms nucleic acid polymers occurs between a <u><em>Phosphate</em></u> group on one nucleotide and a <u><em>hydroxyl group of sugar</em></u> on a second nucleotide.
Explanation:
- When nucleotides polymerize to form nucleic acids, the hydroxyl group attached to the 3′ carbon of a sugar of one nucleotide forms an ester bond to the phosphate of another nucleotide, eliminating a molecule of water.
Summary:
So the phosphate group of one nucleotide form bond with the hydroxyl group of an other nucleotide with the elimination of water molecules.
Answer:
AuCl
Explanation:
The solubility product constant, ksp, is defined as:
MₓYₙ(s) ⇄ xMⁿ⁺(aq) + nYˣ⁻(aq)
ksp = [Mⁿ⁺]ˣ + [Yˣ⁻]ⁿ
Thus, the higher ksp, the more soluble the compound is. Thus, the lower ksp the less soluble the compound is precipitating first. As the lower ksp is for Au, the first compound in precipitate is <em>AuCl</em>

The answer is a conductor. Metals are good conductors of heat. ... the close packing of the metal ions in the lattice. the delocalised electrons can carry kinetic energy through the lattice.
