<u>Answer:</u> The amount of heat released is 56 MJ.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of
= 12 kg = 12000 g (Conversion factor: 1 kg = 1000 g)
Molar mass of
= 30 g/mol
Putting values in above equation, we get:
![\text{Moles of }C_2H_6=\frac{12000g}{30g/mol}=400mol](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DC_2H_6%3D%5Cfrac%7B12000g%7D%7B30g%2Fmol%7D%3D400mol)
The chemical reaction for hydrogenation of ethene follows the equation:
![C_2H_4+H_2\rightarrow C_2H_6](https://tex.z-dn.net/?f=C_2H_4%2BH_2%5Crightarrow%20C_2H_6)
By Stoichiometry of the reaction:
When 1 mole of ethane releases 140 kJ of heat.
So, 400 moles of ethane will release =
of heat.
Converting this into Mega joules, using the conversion factor:
1 MJ = 1000 kJ
So, ![\Rightarrow 56000kJ\times (\frac{1MJ}{1000kJ})=56MJ](https://tex.z-dn.net/?f=%5CRightarrow%2056000kJ%5Ctimes%20%28%5Cfrac%7B1MJ%7D%7B1000kJ%7D%29%3D56MJ)
Hence, the amount of heat released is 56 MJ.
Neutrons released during a fission reaction trigger other fission reactions.

Answer:
Below
Explanation:
The balanced equation for h202 = h20 + 02 is:
2H2O2 = 2H20 + O2
The coefficients would be 2
The balanced equation for Na + I2 = NaI is:
2Na + I2 = 2NAI
The coefficients would be 2
