Answer:

2.2508\times 10^{19} m meter the mean free path of hydrogen atoms in interstellar space.Explanation:

The mean free path equation is given as:

\lambda =\frac{1}{\sqrt{2}\pi d^2 n}

Where"

d = diameter of hydrogen atom in meters

n =  number of molecules per unit volume

We are given: d = 100 pm = 100\times 10^{-12}= 10^{-10} m

n = 1 m^{-3}

\lambda =\frac{1}{\sqrt{2}\pi (10^{-10} m)^2\times 1 m^{-3}}

\lambda =2.2508\times 10^{19} m

2.2508\times 10^{19} m meter the mean free path of hydrogen atoms in interstellar space.

Which is the most accurate description of compounds?
baherus [9]

Answer: c.They have a unique set of properties that can be used as identifiers.

Explanation:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.

Compounds can be decomposed into simpler constituents using chemical reactions.

Example: Water (H_2O)

2H_2O\rightarrow 2H_2+O_2

Compounds have different properties than the elements it is made up of.

Thus the most accurate description of compounds is that they have a unique set of properties that can be used as identifiers.
