Answer : The correct option is (c) 
Explanation :
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 3 moles of 
react to give 2 mole of 
So, 1 mole of react to give moles of
Thus, the conversion factor needed to convert the number of moles of to the number of moles of produced is
Hence, the correct option is (c)
Larger elements are able to form in a supernova explosion because the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron to be produced.
<h3>What is Supernova?</h3>
This is referred to the explosion of a star and it resulting in larger elements being formed through a process known as nucleosynthesis and is usually accompanied by an increase in the brightness of the star.
The elements produced are usually larger than elements such as iron and examples include uranium, gold etc.
This is therefore the reason why it was chosen as the most appropriate choice.

The electron sea model for metals suggest that the valence electrons drift freely around the metal cations.
Answer: B
Explanation
The sea model of electron is used for describing the mechanism of metallic bonding.
The metallic bonding generally occurs between 2 or more metals leading to the formation of alloys.
According to electron sea model, the electrons which contributes to the metallic bond are mostly the valence electrons of the atoms, these valence electrons get de-localized and can move freely around the nuclei of other atoms.
Overall, it seems like nuclei of positive charge is surrounded by sea of negative electrons.
