Answer:
30moles of SiO₂
Explanation:
Given parameters:
Number of moles of O₂ = 30moles
Unknown:
Number of moles of SiO₂ = ?
Solution:
To solve this problem, we need to write the reaction expression:
Si + O₂ → SiO₂
The reaction is balanced;
1 mole of O₂ will produce 1 mole of SiO₂
30mole of O₂ will produce 30moles of SiO₂
The difference between an exergonic reaction and an endergonic reaction
is that an exergonic reaction
involves release of energy, while an endergonic reaction involves absorption of
energy.
<span>In an </span>exergonic reaction, energy is released to the surroundings. The
bonds being formed are stronger than the bonds being broken. In an endergonic reaction, energy is absorbed from the surroundings.
The correct answer between all the choices given is the
third choice or letter C. I am hoping that this answer has satisfied your query
and it will be able to help you in your endeavor, and if you would like, feel
