Answer:
Large molecules tend to have greater boiling points because the London dispersion forces are stronger within.

The nature of reactants, temperature, concentration, surface area and catalysts.
        
             
        
        
        
One mole of NaOH (Sodium hydroxide) is equal to 39.997 grams of NaOH. 
        
             
        
        
        
from an external source of power
Explanation:
The energy needed for nuclear fusion comes from an external source of power. 
Nuclear fusion is the combination of small sized atomic nuclei to form larger ones. 
The reaction releases a huge amount of energy but also requires a large activation energy to start up. 
- The energy input require to drive two nuclei into fusion comes from an external source. 
- Nuclear fusion has a high activation energy which serves as the energy barrier for this reaction to take place. 
- The energy comes from the surrounding and once initiated, spontaneous chain reactions are set up.
