Explanation:
Metallic bonds involve attraction between electrons and positively charged metal ions. The metals are ionized and electrons form a sea of valence electrons. These loosely bound electrons surround the nuclei of the metals.
The presence of this sea of electrons explains the fact that metals conduct electricity and heat due to the free valence electrons.
Due to the nature of the bonding between metal atoms,metals are malleable and ductile.
Due to the strong electrostatic interaction between metal ions and electrons, the metallic bond is very strong and is very difficult to break thereby accounting for the greater strength of metals as the size of the metallic ion decreases.

Explanation:
Homogeneous catalysis refers to catalytic reactions where the catalyst is in the same phase as the reactants.
Heterogeneous catalysis is the type of catalysis where the phase of the catalyst differs from the phase of the reactants or products.
Platinum is used to catalyze the hydrogenation of ethylene:
H2(g)+CH2CH2(g)− ⟶ Pt(s) CH3CH3(g)
In this reaction, the platinum is in the solid state. While the other species (reactants and products) are in their gaseous state.
This reaction is Heterogenous catalysis.
Chlorofluorocarbons (CFCs) catalyze the conversion of ozone (O3O3) to oxygen gas (O2O2):
2O3(g)− ⟶ CFC(g) 3O2(g)
The catalyst is in the same gaseous state as the reactant and product.
This reaction is Homogenous catalysis.
Magnesium catalyzes the disproportionation of hydrogen peroxide to produce water and oxygen:
2H2O2(aq)− ⟶ Mg(s) 2H2O(l) + O2(g)
In this reaction, the Magnesium is in the solid state. While the other species (reactants and products) are in their gaseous state.
This reaction is Heterogenous catalysis.
Answer:
The solute that is most likely soluble in hexane is S₈
Explanation:
S₈ is a non-polar solute that exhibits the same characteristics and properties as hexane. Following the common principle "like dissolves like"; polar compounds will be soluble in polar solvents while non-polar compounds will be soluble in non-polar solvents. As such, since S₈ is non-polar, then it will be soluble in hexane.
