Question

1. Place the molecules in the list in order with the smallest molecules at the top and the largest molecules at the bottom.

= glucose molecule

= starch molecule

= protein molecule

= carbon dioxide molecule

= water molecule

= amino acid molecule

= oxygen molecule

Answer 1

Answer:

Explanation:

In creating this list, one will have to start from the atom (which is the smallest in the list) to the giant polymer (which is the largest in the group). The arrangement below will also be based on there molecular weight.

oxygen molecule (this is the first because it is an atom)

water molecule (this is lighter in weight than carbon dioxide)

carbon dioxide

amino acid molecule (most amino acids have a lesser molecular weight than glucose)

glucose (has a molecular weight of 180.156 g/mol)

protein molecule (several proteins have a lesser molecular weight than starch)

starch molecule (has a molecular weight of 359.33 g/mol)

Answer 2

The arrangement of molecules in the ascending order is: oxygen, water, carbon dioxide, amino acid, glucose, starch, and protein.  

• The size of the molecules can be determined by knowing their molecular weights.  

• The sum of the atomic weights of the atoms in the molecule is known as the molecular weight of the molecule.  

• The molecular weight of water is 18 gram per mole, glucose 180.2 g/mol, starch 360 g/mol, carbon dioxide 44 g/mol, protein 20000 g/mol, amino acid for example glycine 75 g/mol, and oxygen 16 g/mol.  

Thus, the molecules can be arranged with the smallest to the largest as oxygen, water, carbon dioxide, amino acid, glucose, starch, and protein.
