Answer:
It could take several thousands of years.
Explanation:
To be specific, the exact number of stars in the galaxy is unknown, it's estimated to have around 100 to 400 billion stars.
But for the sake of this test, let's take as valid a recent study of the European space agency, that believes that we have 100 billion stars orbiting our galaxy.
If you could count 1 every second it would mean you'll need at least 100 billion seconds to do it. How many days is that?
We have:
100 billion seconds = 1.666 billion minutes
1.666 billion minutes = 27.777 million hours
27.777 million hours = 1,157 million days = 3,170 years.
You would need at least, 3170 years of spare time, considering that you will do no other thing than counting stars for the next 3 millennia.
Answer:
The radioactive isotope content of a rock can be used to identify the rocks age.
<span>Answer:
The carbons on the closures are sp² hybridized, with a p-orbital for the 'second' bond in the twofold bond with their neighboring carbons.
They have those sp² orbitals covering with the s from the hydrogen, and they have a p covering in the pi bond with the neighboring carbon. They likewise have a sigma bond with the neighboring carbon I'll get to.
The center carbons each have two pi bonds with their neighbors, leaving sp hybridiaztion for the rest. So they have sp/sp² with the end carbons, and sp/sp with each other. (What's more, they likewise have p/p in the pi bonds).
So the total list is:
s/sp²
p/p
sp/sp²
sp/sp</span>
