Answer:
The pressure inside the container is 34.97 atm
Explanation:
Given:
V=50L R= 0.0821LatmK^-1mol^-1
n= 45mol T= 473k
PV=nRT
P= nRT/V
= 45mol*0.0821Latmmol^-1K^-1*473K/ 50L
=34.95atm
your answer will be March 3
The amount left after 20 years = 154.15 mg
<h3>Further explanation
</h3>
The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.
Usually radioactive elements have an unstable atomic nucleus.
The main particles are emitted by radioactive elements so that they generally decay are alpha (α), beta (β) and gamma (γ) particles
The decay formula for isotope :

Then for t=20 years, the amount left :

Answer:
kinetic energy than the potential energy it carries
