27 km = 27000m. Time = distance/speed = 27000/3x10^8 = 9x10^-5 s.
Answer : The total mass of carbon dioxide and water produced will be, 65.7 grams.
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of 
= Total mass of 
As we are given :
Total mass of = 65.7 grams
So,
65.7 grams = Total mass of
Therefore, the total mass of carbon dioxide and water produced will be, 65.7 grams.

Answer:
A red giant is a luminous giant star of low or intermediate mass in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K or lower.
