Answer:
1. The Dean's theory is an untested idea that he will investigate; scientific theories have already been investigated.
Explanation:
Scientific theory by definition is something that can be tested. However, in science, a scientific theory generally is something that has already been tested (hence the scientific definition). Remember from math, Theorem is something that can be tested, Postulate is something you can't. By prescribing theorem on it, it means that you can test whether it is true or not.
As for the Dean, he has a "theory" of why phones are being stolen from student backpacks. However, it seems that he did not test for it (i.e., install security cameras, etc.). This means that, without testing, he cannot say it is a scientific theory.
Since the chemical definition of "stable" means close to having a full valence shell, the answer is 3d^10.

Answer:
4560 Torr
Explanation:
<u>Boyle's Law</u>
where:
- = initial volume
- = final volume
- = initial pressure
- = final pressure
Given:
Substituting the given values into the formula:
To convert atm to Torr, multiply atm by 760:
