Since no choices are given, I will describe the reactivity of the element chlorine. A halogen is example of
nonmetal. When compounds containing halogens they are
called salts thus the name “salt – former”. Halogen consists of Fluorine,
Chlorine, Bromine, Iodine, Astatine. An example of is reactivity is the monochlorination of
an alkane, which involves substituting one of the hydrogen atom in the alkane and
exchange it with a chlorine atom.
CH₄ + Cl₂ → CH₃Cl + HCl
The H in methane is substituted with the
Cl in chloride.
It's very dangerous to go that deep into the ocean due to the water pressure and the coldness, no human can physically comprehend it, so if you do end up diving that deep into the ocean, you will suffocate, crush to death, or freeze very quickly.
We see that in 1 rock, there are 31 atoms of Argon and 1
atom of Potassium so the relative concentration of Potassium is:
1 / 32
or can be written as:
1 / 2^5
So this means that 5 half-lives have passed.
So the years are:
<span>years passed = 5 * 1.25 billion years = 6.25 billion years</span>
Answer:
More than 50% of the 100 billion stars in the Milky Way galaxy have at least one planet orbiting.
