Answer:
The heat energy stored within them changes
Explanation:
Heat energy is a function of the mass of a body, its specific heat capacity, and its temperature.
In this case, the bodies have the same specific heat capacity since they are made from the same material and the same temperature.
To get the quantity of heat stored in a body, we need to multiply all three parameters as shown below
![Q = mC \Delta T](https://tex.z-dn.net/?f=Q%20%3D%20mC%20%5CDelta%20T)
An increase in mass, through an increase in the amount of substance of a material present, will cause a corresponding increase in the heat energy stored within the material
The units for measuring ions, molecules or atoms are called moles. Water decomposes to form hydrogen and oxygen as follows:
![\rm 2 \;H_{2}O \rightarrow 2 \;H_{2} + O_{2}](https://tex.z-dn.net/?f=%5Crm%202%20%5C%3BH_%7B2%7DO%20%5Crightarrow%20%202%20%5C%3BH_%7B2%7D%20%2B%20O_%7B2%7D)
Moles of hydrogen produced will be:
Option C. 12.6 mol
The moles can be estimated as:
- The molar ratios can be written as:
2 mol
: 2 mol
: 1 mol ![\rm O_{2}](https://tex.z-dn.net/?f=%5Crm%20O_%7B2%7D)
- The proportions and theoretical values are written as:
Let the moles of
= X
Then,
![[\dfrac {2 \text{mol H}_{2} }{1 \text{mol O}_{2}} ] = \dfrac {\text{X mol H}_{2}}{ 6.28\; \rm mol \;\rm O_{2}}]](https://tex.z-dn.net/?f=%5B%5Cdfrac%20%7B2%20%5Ctext%7Bmol%20H%7D_%7B2%7D%20%7D%7B1%20%5Ctext%7Bmol%20O%7D_%7B2%7D%7D%20%5D%20%3D%20%5Cdfrac%20%7B%5Ctext%7BX%20mol%20H%7D_%7B2%7D%7D%7B%206.28%5C%3B%20%5Crm%20mol%20%5C%3B%5Crm%20O_%7B2%7D%7D%5D)
From this it can be depicted that hydrogen produced is double compared to oxygen produced.
Solving further for X:
![\begin{aligned}\rm X &= \dfrac {6.28 \text{mol O}_{2} \times \text{2 mol H}_{2} }{ 1 \text{mol O}_{2}} \\\\&= 12.56 \;\text{mol O}_{2}\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Crm%20X%20%26%3D%20%5Cdfrac%20%7B6.28%20%5Ctext%7Bmol%20O%7D_%7B2%7D%20%5Ctimes%20%20%5Ctext%7B2%20mol%20H%7D_%7B2%7D%20%7D%7B%201%20%5Ctext%7Bmol%20O%7D_%7B2%7D%7D%20%5C%5C%5C%5C%26%3D%2012.56%20%5C%3B%5Ctext%7Bmol%20O%7D_%7B2%7D%5Cend%7Baligned%7D)
Therefore, 12.56 moles are produced of hydrogen.

Reactants and products contain the same atoms, but they are rearranged during the reaction, so they are different substances
