Answer with Explanation:
1. An "x-ray image" shows the difference between the bones and soft tissues because the <em>bones appear white in color </em>while the <em>soft tissues appear gray in color. </em>
2. The reason behind the difference in the appearance of bones and soft tissues on the x-ray film is their<em> density.</em> <u><em>Bones are denser than soft tissues</em></u>, which means that<em> its atoms are closely-knitted when compared to the soft tissues that are far apart from each other. </em>This allows the<em> </em><em>x-ray radiation to be absorbed by the bone </em>while <em>it passes through most of the soft tissues.</em>
This is the reason why pregnant women are advised not to undergo an x-ray examination because<u><em> the fetus is denser and it will surely absorb the x-ray radiation.</em></u>
The volume of the gas is 180.26 L, if there are 63.5 mol of an ideal gas at 9.11 atm at 42.80 °C.
Applying the ideal gas law PV= nRT
After rearranging the aforementioned expression, the volume might then be found as: V= n R T/ P.
Consequently, V= 63.5 mol, 0.0821, 315 K, and 9.11 atm equal 180.26 L.
<h3>How is the ideal gas equation defined?</h3>
The ideal gas equation is PV = nRT. In this equation, P denotes the ideal gas's pressure, V its volume, n its total amount, expressed in moles, and R its resistance for the universal gas constant, and T for temperature.

<h3>Further explanation

A buffer solution is a solution that can maintain a good pH value due to the addition of a little acid or a little base or dilution.
The buffer solution can be acidic or basic
Acid buffer solutions consist of weak acids and their salts.
A buffer solution of NaC2H202 and HC2H2O2 (acetic acid) is included in the acid buffer
So :
a slight addition of acid (H⁺) will be balanced by the conjugate base
the addition of a small base (OH⁻) will be balanced by the weak acid
With the addition of acid (H +), the equilibrium will shift to the left, in the formation of CH3COOH. The added acid will be neutralized by the conjugate base component (CH3COO−).
