Question

1. consider the following reaction: c₆h₁₂o₆ + c₆h₁₂o₆ → c₁₂h₂₂o₁₁ a. the equation is not balanced; it is missing a molecule of water. write it in on the correct side of the equation. c₆h₁₂o₆ + c₆h₁₂o₆ → c₁₂h₂₂o₁₁ + h₂o b. polymers are assembled and broken down in two types of reactions: dehydration synthesis and hydrolysis. which kind of reaction is this? c. is c₆h₁₂o₆ (glucose) a monomer or a polymer? d. to summarize, when two monomers are joined, a molecule of is always removed.

Explanation:

Step1: Balance the equation

In a dehydration - synthesis reaction, when two monosaccharides combine to form a disaccharide, a water molecule is produced. The balanced equation for the combination of two glucose ($C_6H_{12}O_6$) molecules to form sucrose ($C_{12}H_{22}O_{11}$) is $C_6H_{12}O_6 + C_6H_{12}O_6
ightarrow C_{12}H_{22}O_{11}+H_2O$.

Step2: Identify the reaction type

Dehydration synthesis is a reaction where two molecules are joined together with the loss of a water molecule. Hydrolysis is the reverse, where a molecule is broken down using water. Since water is produced in the given reaction, it is a dehydration - synthesis reaction.

Step3: Determine if glucose is a monomer or polymer

A monomer is a single unit that can join with other monomers to form a polymer. Glucose ($C_6H_{12}O_6$) is a monosaccharide and can combine with other monosaccharides to form polysaccharides. So, glucose is a monomer.

Step4: Summarize the general rule

When two monomers are joined in a dehydration - synthesis reaction, a molecule of water is removed.

Answer:

a. $C_6H_{12}O_6 + C_6H_{12}O_6
ightarrow C_{12}H_{22}O_{11}+H_2O$
b. Dehydration synthesis
c. Monomer
d. Water
