Answer:
- Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. or
- Starch is a long-chain polymer of glucose molecules joined together. or
- A starch is a complex polysaccharide made up of a large number of glucose units joined together by glycosidic bonds.
Explanation:
starch, a white, granular, organic chemical that is produced by all green plants. Starch is a soft, white, tasteless powder that is insoluble in cold water, alcohol, or other solvents.
Starch is amongst the most abundant plant products and is a mixture of two polymers, amylose and amylopectin. During food processing starch is transformed by hydrothermal treatments. ... The structure of starch is also influenced by specific and non-specific interactions with other food constituents and ingredients.
Answer:
C. Atom
The formula weight is calculated by the sum( adding) of the atomic masses for every atom in the formula
Addition reaction between water molecules and alkene molecules produces alcohol.
<h3>What is addition reaction?</h3>
Addition reaction generally takes place across the unsaturated carbon compounds.
When water molecule (H₂O) is added to the alkene which may be ethene (C₂H₄) molecule then formation of product i.e. ethanol (CH₃CH₂OH) takes place through the addition of hydrogen and hydroxyl group across the double bond. And reaction is shown in the attached image.
Hence formation of alcohol product takes place.

Resonance or mesomerism is applicable to structures that cannot be formed with a single bond alone. Thus, for the structure of HCO2, there can be 2 resonance structures. In each structure, the formal charges are
C=0;
C=0
Oxygen=0
C-O=-1
H=0
HCO2-'s structure is a mixture of the two resonance structures. Hope this helps.
