.help!!! due today!!! what is happening and how it is demonstrating Newton’s 1st law. make sure you describe inertia and how it
relates to your demonstration.
okayyy so ive got to make a video and im planning on making this but then i have to explain how is it demonstrating Newton's 1st law and then I have to describe how Inertia relates to this demonstration, please help a girl out!!!

Answer:
The radius of tantalum (Ta) atom is
Explanation:
From the Body-centered cubic (BBC) crystal structure we know that a unit cell length <em>a </em>and atomic radius <em>R </em>are related through
So the volume of the unit cell is
We can compute the theoretical density ρ through the following relationship
where
n = number of atoms associated with each unit cell
A = atomic weight
= volume of the unit cell
= Avogadro’s number (
atoms/mol)
From the information given:
A = 180.9 g/mol
ρ = 16.6 g/cm^3
Since the crystal structure is BCC, n, the number of atoms per unit cell, is 2.
We can use the theoretical density ρ to find the radio <em>R</em> as follows:
Solving for <em>R</em>
Substitution for the various parameters into above equation yields
The reaction is balanced
The equilibrium constant is defined as the concentration ratio of the products and reactants. They are not considered pure solids and liquids.
So the answer is option B.
