Answer:

1. The Big Bang theory is considered as the most accepted theory on the origin of the universe.  

2. Steady state theory focuses on the fact that all is the same and will always remain the same.  

3. The oscillating universe theory agrees with the Big Bang theory, however, considers that the universe stretched much more rapidly.  

4. Inflation theory is a theory that is like a deflating and inflating balloon, which never ceases.

Mercury(ii) oxide (hgo) decomposes to form mercury (hg) and oxygen (o2). the balanced chemical equation is shown below. 2hgo rig
Verizon [17]

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:

\begin{aligned}\rm n &= \rm \dfrac {mass}{molar\; mass}\\\\&= \dfrac{250}{32}\\\\&= 7.8125 \;\rm moles\end{aligned}

The balanced chemical reaction can be shown as,

\rm 2HgO \rightarrow 2Hg + O_{2}

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:

\begin{aligned}  \rm n HgO& = (7.8125 \;\rm moles \; O_{2}) \times (\dfrac{2 \;\rm moles\;  HgO}{1 \;\rm mole \; O_{2}})\\\\\rm n HgO &= 15.625 \;\rm moles \end{aligned}

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