Decomposition reaction results in the formation of the products by splitting the reactants. Moles of mercury(ii) oxide needed are 15.63 moles.
<h3>What are moles?</h3>
Moles are the ratio of mass and the molar mass of the compound or the molecule.
Moles of oxygen are calculated as:

The balanced chemical reaction can be shown as,

From the reaction, it can be said that 1 mole of oxygen requires 2 moles of mercury oxide.
Moles of mercury oxide are calculated as:

Therefore, option C. 15.63 moles of mercury (II) oxide is needed.

Answer:
(1) I shifts toward product and II shifts toward reactant.
Explanation:
Increasing the temperature of an endothermic reaction (∆H is positive) shifts the equilibrium position to the right thus favoring product formation.
Increasing the temperature of an exothermic reaction (∆H is negative) shifts the equilibrium position to the left thus favoring the backward reaction.
Answer:
water, host
Explanation:
Clathrate hydrates are the crystalline water-based solids which physically resembles with the ice, in which the small non-polar molecules or smaller polar molecules with the large hydrophobic moieties are usually trapped inside the "cages" of the hydrogen bonded as well as frozen water molecules.
<u>Clathrate hydrates are the clathrate compounds in which water creates the cage and the water behaves as a host molecule and guest molecule is typically a gas or liquid.</u>
