Answer:
A They are attracted to a magnet
Noble Gas Cores have following electronic configuration
He = 1s²
Ne = [He] 2s², 2p⁶
Ar = [Ne] 3s², 3p⁶
Kr = [Ar] 4s², 4p⁶
Xe = [Kr] 5s², 5p⁶
Now solving for question elements,
Germanium = Ge = [Ar] 3d¹⁰, 4s², 4p²
Nickle = Ni = [Ar] 3d¹⁰, 4s²
Tunsten = W = [Xe] 4f¹⁴, 5d⁴, 6s²
Titanium = Ti = [Ar] 3d², 4s²
Iron = Fe = [Ar] 3d⁶, 4s²
Zinc = Zn = [Ar] 3d¹⁰, 4s²
The number of moles of CO₂ that is produced when burning 6.0 mol of ethanol is 12 mol.
<h3>What is Balanced Chemical Equation ?</h3>
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
Now we have to write the balanced equation
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
We can see that every 1 mole of ethanol we will get 2 mole of CO₂.
So 6.0 mol of ethanol we will get = 6.0 × 2.0
= 12 mol of CO₂
Thus from the above conclusion we can say that The number of moles of CO₂ that is produced when burning 6.0 mol of ethanol is 12 mol.

Written Answer: Covalent bonds hold atoms together in molecules and polyatomic ions where as intermolecular forces hold molecules together in a liquid or solid. Intermolecular forces are generally much weaker than covalent bonds.
Explanation/Evidence: "In contrast to intramolecular forces, such as the <u>covalent bonds that hold atoms together in molecules and polyatomic ions</u>, <u>intermolecular forces hold molecules together in a liquid or solid.</u> <u>Intermolecular forces are generally much weaker than covalent bonds."</u>
