Answer:
c. 2.16 × 10^8 kJ
Explanation:
In the given question, 2 C-12 nuclei were used for the reaction and the mass of C-12 is 12.0000 amu. Therefore, for 2 C-12 nuclei, the mass is 2*12.0000 = 24.0000 amu.
In addition, a Na-23 and a H-1 were formed in the process. The combined mass of the products is 22.989767+1.007825 = 23.997592 amu
The mass of the reactant is different from the mass of the products. The difference = 24.0000 amu - 23.997592 amu = 0.002408 amu.
Theoretically, 1 amu = 1.66054*10^-27 kg
Thus, 0.002408 amu = 0.002408*1.66054*10^-27 kg = 3.99858*10^-30 kg
This mass difference is converted to energy and its value can be calculated using:
E = mc^2 = 3.99858*10^-30 *(299792458)^2 = 3.59374*10^-13 J
Furthermore, 1 mole of hydrogen nuclei contains 6.022*10^23 particles. Thus, we have:
E = 3.59374*10^-13 * 6.022*10^23 = 2.164*10^11 J = 2.164*10^8 kJ
Fossil fuels are an important natural resource used by society and they are organic fuels derived from ancient plants and animals.
<h3>What are fossil fuels?</h3>
Fossil fuels are the natural resources means they are derived from the ancient resdue of plants and animale due to theor decomposition under high temperature and pressure.
- Fossil fuel may be present in solid, liquid as well as in gaseous form so the given option (a) is incorrect.
- This is the wrong assumption that in the fossil fuel we get the fossils of dinosaur, so option (c) is incorrect.
- They are not inorganic fuels infact they are organic fuels.
So, fossil fuels are organic fuels derived from ancient plants and animals.
the kinetic energy is the same as the canoes weight times its speed times the force of gravity.
Answer:
acid turns blue litmus red and base turns red litmus blue
Would love to answer but "descibe by the minerals" makes no sense
