The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.
I think the answer is ZnS
An old star dies out, causing a supernova, causing hot gases to accumulate, creating the Sun.
Answer:
A). 2.1 ×
Explanation:
Given reaction,
2 (g) ⇄ (g) + (g)
The concentrations are as following;
= 5.82 × M
= 8.4 × M
= 8.4 × M
So,
= [( ) × ()] ÷ []^2
Now,
We can determine the value of by substituting the values in above formula:
= [ (8.4 × M) × (8.4 × M)] ÷ [(5.82 × )^2
= 2.08 *
= 2.1 ×
∵ = 2.1 ×
Thus, <u>option A</u> is the correct answer.
