The Answer is D: Reactor products charge huge batteries.
Answer:
The mean free path is 
Explanation:
The formula for mean free path is :
λ = 
<em>where,</em>
<em>λ - is the mean free path distance</em>
<em>V - volume of the gas</em>
<em>d - the diameter of the molecule</em>
<em>N - number of molecules.</em>
now ,
<em>density
=
=
;</em>
<em>mass of the gas = (number of molecules)
(mass of one molecule) ;</em>
<em>as it's atomic hydrogen </em>

∴
= 
∴

⇒ λ = 
⇒ λ = 
⇒ λ = 
Its A 3181.1 j and now im just typing random stuff cause for some reason i cant answer the question without extra
To calculate for the volume of a substance, simply get the
ratio of the mass and density. That is:
Volume = mass / density
Therefore by substitution:
Volume = 2.50 g / (0.992 g / mL)
<span>Volume = 2.52 mL</span>
Answer:
<h3>The answer is 7.21 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of metal = 86.5 g
volume = 12 mL
The density is

We have the final answer as
<h3>7.21 g/mL</h3>
Hope this helps you
