unless you are an ant then yes
Explanation:
Answer:
16.7 days
Explanation:
We are given;
A radioactive isotope Iodine-131`
The decay rate is 0.138 d⁻¹
The percent decayed is 90%
We are suppose to calculate the number of days for the decay.
![In(\frac{[A_{0}]}{[A]})=kt](https://tex.z-dn.net/?f=In%28%5Cfrac%7B%5BA_%7B0%7D%5D%7D%7B%5BA%5D%7D%29%3Dkt)
Where, ![[A_{0}]](https://tex.z-dn.net/?f=%5BA_%7B0%7D%5D)
is the initial concentration and ![[A]](https://tex.z-dn.net/?f=%5BA%5D)
is the new concentration.
![t=In(\frac{[A_{0}]}{[A]})/k](https://tex.z-dn.net/?f=t%3DIn%28%5Cfrac%7B%5BA_%7B0%7D%5D%7D%7B%5BA%5D%7D%29%2Fk)
Assuming the initial concentration is x, then the final concentration after 90% decay will be 0.10x
Therefore;
![t=In(\frac{[x]}{[0.10x]})(\frac{1}{0.138})](https://tex.z-dn.net/?f=t%3DIn%28%5Cfrac%7B%5Bx%5D%7D%7B%5B0.10x%5D%7D%29%28%5Cfrac%7B1%7D%7B0.138%7D%29)
![t=In(\frac{[1]}{[0.10]})(\frac{1}{0.138})](https://tex.z-dn.net/?f=t%3DIn%28%5Cfrac%7B%5B1%5D%7D%7B%5B0.10%5D%7D%29%28%5Cfrac%7B1%7D%7B0.138%7D%29)
Time = 16.7 days
Therefore, it will take 16.7 days for 90% of I-131 to decay to Xe-131
Answer:
The solid layer of fat on top protects the broth from freezer burn. When I take the broth out of the freezer I use a butter knife to pop the fat cap off before defrosting. I do save chicken fat from soup and use it instead of butter or olive oil when I cook onions.

Answer:
HCI
Explanation:
The solution with the lowest pH is HCI with a pH value of 1. It is understood that it is more acidic because it is a strong acid.
The generic reaction a + b = c, represents a synthesis or combination reaction, which is a kind of chemical reaction.
<h3>What is a synthesis reaction?</h3>
A synthesis, or combination reaction, is a kind of reaction in which two substances combine to form a bigger molecule.
The generic reaction is:
a + b = c
Some common synthesis reactions are:
- Two elements combine to form a compound.
Fe + S = FeS
- One element and one compound combine to form a compound.
O₂ + 2 SO₂ = 2 SO₃
- Two compounds combine to form another compound.
CaO + CO₂ = CaCO₃
In all the examples above, we can verify that the substances (elements or compounds) combine with each other to form another substance (product).
