Answer : Nuclear fusion plays an important role in making elements that are heavier than helium.
Explanation : In the given attachment it is clearly observed that nuclear fusion reactions are playing a vital role in making the small elements fuse together to form a higher element as a product. This is observed in those elements which are heavier than helium. The atoms of the elements fuse together and make a larger atomic molecule which is the sum of both the elemental masses.
Sodium Carbonate(NaCO3) gives off heat hence the reactions involving Na2CO3 are exothermic.
Hope this helps!
24.5 / 14 = 1.75
70 / 16 = 4.375
4.375 / 1.75 = 2.5
empirical formula = N2O5
“Chemical reaction” is the answer
The two molecular characteristics of substances that typically form liquid cyrstals and there phases are long, cylindrical shape and between molecules & strong intermolecular forces exist
All these enables different application of liquid crystals
