Answer: I have no idea what kind of question this is, but I'm assuming it's a true or false question, and this is true. Although the north-bound pole is south-seeking, a compass would eventually draw you to the North Pole.
Explanation:
Answer: 22 neutrons
Explanation: 40 is the mass number = atomic mass = total number of protons and neutrons in atomic nucleus
18 is the number of protons in the nucleus of this atom
Then 40 - 18 = 22 neutrons
and this is Argon
Hi there!
Rutherford's experiment showed that the atom's nucleus <em>did </em>have a positive charge. The α particles' trajectory was altered when it went through the gold foil, which, in turn resulted in the discovery of the atom's positive charge.
I hope this helps!

Answer:
<h3>The answer is 0.622 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
![volume = \frac{mass}{density} \\](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7Bmass%7D%7Bdensity%7D%20%20%5C%5C%20)
From the question
mass = 12 g
density = 19.30 g/mL
We have
![volume = \frac{12}{19.30} \\ = 0.62176165...](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B12%7D%7B19.30%7D%20%20%5C%5C%20%20%3D%200.62176165...)
We have the final answer as
<h3>0.622 mL</h3>
Hope this helps you
