Yes! You're correct! Hope this helps! :D
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:

The answer would be A. You cannot decrease mass because of increasing temp so it can't be C and adding neutrons or protons would be changing the atom and therefore the element, and that is not possible through just an increase of temperature, so it can't be B or D. Hope this was helpful! ;)
