The log will float on the water because his density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
<span>Archimedes' principle is a physical law that describes the upward force (the vertical thrust) experienced by any body immersed in a fluid (liquid or gas). This force is strongly related to the density of both the fluid and the body.

You can try the experience at home, by using an object that has a lower density than the water like the sunflower oil, you will see that it will stay at the top of the water too.

Answer</h2>
The monosaccharides is formed by just bounding of C, H and O.
<h2>
Explanation</h2>
Monosaccharides are simplest molecule or unit in the carbohydrates group which united with each other to form di, tri or polysaccharide structure. As these are the simplest unit in carbohydrates, they are only formed by numbers of carbon, oxygen and hydrogen atoms. The number of atoms in the chain of monosaccharides varies with changing required compound. for example in deoxyribose, one of hydrogen is not present in its structure but present in ribose.
