Answer:
2.04 mol

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>
Incomplete combustion<span> occurs when the supply of air or oxygen is poor. Water is still </span>produced<span>, but </span>carbon<span> monoxide and </span>carbon<span> are </span>produced<span> instead of </span>carbon dioxide<span>. The </span>carbon<span> is released as soot. </span>Carbon<span> monoxide is a poisonous gas, which is one reason why </span>complete combustion<span> is preferred to </span>incomplete combustion<span>.</span>
