Answer:
2.15 mg of uranium-238 decays
Explanation:
For decay of radioactive nuclide-

where N is amount of radioactive nuclide after t time,
is initial amount of radioactive nuclide and
is half life of radioactive nuclide
Here
,
and 
So,
so, N = 2.446 mg
mass of uranium-238 decays = (4.60-2.446) mg = 2.15 mg

i used an online converter lol it is much faster. if you'd like a step by step guide comment and ill give you one :)
The water reaches its boiling point and turns into water vapor. This process is a physical change. The change is substance status. And the physical change will not destroy the molecular structure. So the molecular structure will not change.
A Plate Boundaries and Movement Lab Report is a report that shows the records of all the data relating to the movement of Plate Boundaries and their movements.
<h3>What are Plates in this context?</h3>
A tectonic plate is also described or referred to as a Lithosperic Plate. In Geography, it is described as a slab of rock that is not shaped regularly.
In most cases, it comprises continental and oceanic lithosphere.
<h3>Why is it crucial to record the movement of plates and their boundaries?</h3>
Plate Boundaries and their movement are largely linked to volcanic activities and earthquakes. This means that they can be used to predict when any of the above-mentioned events may happen.
