A) Al4C3 moles in 100g=100g/144gmol¹-
Molar mass of Al4C3=144gmol¹-
one mole of Al4C3 reacts with 12 moles of water
required H2O moles=100/144*12=8.33mol

Explanation:
One gram of U-235 produces approximately 2,000,000 times more energy than one gram of coal.
The energy in 1g of U-235 is a nuclear energy whereas energy obtained from coal is chemical energy by combustion. During combustion chemical bonds are broken between the carbon atoms.
- Uranium decays the radioactive fission.
- When it is bombarded with particles, an artificial disintegration is induced.
- Most nuclear reactions are chain reactions in which one step leads to another until stability is produced.
- Each step produces energy for the next process.
