Mg is what you measure them in
Answer:
4g of the radioactive element present
Explanation:
Radioactive elements are atoms that are unstable in normal conditions and are converted in another different atoms.
1 half life express the time that is need to decay the half of the initial amount of the radioactive element.
If initially we have 8g of the radioactive element, after 1 life we will have 8g/2 =
4g of the radioactive element present

Explanation:
Quart is a unit of measurement for liquids and is equivalent to 2 pints.
Some people weren't convinced with the theory. Also many people tried to prove that the atom didn't exist, or at least prove the theory wrong.
Explanation:
Your chemical equation should look like this:
Li3PO4 + AlF3 --> 3LiF + AlPO4
This is the balanced equation for a double-displacement reaction
