Long polymers made of monosaccharides that have been linked through dehydration reactions are called polysaccharides.
<h3>What are long polymers made of monosaccharides that have been linked through dehydration reactions called?</h3>
Monosaccharides are known as simple sugars
Monosaccharides can be linked together by dehydration reactions to form long polymeric chains.
The long polymers are known as polysaccharides.
Therefore, long polymers made of monosaccharides that have been linked through dehydration reactions are called polysaccharides.

In the reaction, fluorine and chlorine are present as reactants. Fluorine is a stronger oxidizing agent than chlorine, as fluorine has the tendency to be reduced. Keep in mind that oxidation is when there is an increase in the oxidation number of a substance and reduction is when there is a decrease in the oxidation number. Therefore, the correct statement becomes:
Cl- oxidizes to Cl and F reduces to F-.
