I believe a chloride salt of the benzocaine is the product as the HCl acid attacks the amine functional group. however ethanol may also be formed from the hydrolysis of the ester and create a carboxyl group attached to the benzene ring. This will leave two products at the end of the reaction. I myself need some clarification on the resulting products whether it be a mixture of 2 products or one product.

Benzocaine can be synthesized by reacting p-aminobenzoic acid with ethanol and sulfuric acid, followed by neutralization with sodium hydroxide. This reaction forms benzocaine, which is a local anesthetic commonly used for relieving pain and itching.

Why do you use NaHCO3 in the synthesis of benzocaine?
NaHCO3 is used in the synthesis of benzocaine to neutralize the excess acid used in the reaction. This helps in maintaining the desired pH required for the reaction to proceed efficiently. Additionally, NaHCO3 helps in the separation of the benzocaine product from the reaction mixture by forming a separate aqueous layer.
Another name for a composition reaction is?
Formation reaction.
What is the balanced equation for the production of benzocaine from PABA aka para-aminobenzoic acid and ethanol?
The balanced equation for the production of benzocaine from PABA (para-aminobenzoic acid) and ethanol involves the esterification reaction. It can be represented as PABA + Ethanol → Benzocaine + Water. This reaction is catalyzed by an acid catalyst, such as sulfuric acid, and the water produced is removed by azeotropic distillation to drive the equilibrium towards the formation of benzocaine.
What kind of reaction is represented by 2K I2 -2KI?
The given reaction is an example of "synthesis" reaction, in particular one in which two elements react to form a chemical compound.
What is another term for synthesis reaction?
DNA synthesis is also known as DNA replication.
The reaction in which two or more substances react to form a single substance?
A synthesis reaction or dehydration synthesis, also called a condensation reaction.
Another name for a composition reaction is?
Formation reaction.
Why is ethanol used in excess in the preparation of benzocaine?
to shift the reaction toward the products (Benzocaine) to counteract the imposed change excess reactants so that will lead to a higher percentage of Benzocaine. according to Le Chatelier's principle

A chemical reaction in which two elements combine to form a compound is called a?
synthesis reaction
In which type of reaction does one reactant form two or more products?
A decomposition reaction is when one reactant breaks down into two or more products. It is the opposite of a synthesis reaction.

What reaction is synthesis?
When from two substances is obtained a new substance the reaction is called synthesis.
Is digestion a synthesis reaction?
Is this reaction an illustration of synthesis or digestion
Is frying an egg a synthesis reaction?
Frying an egg is a synthesis reaction. The combination of heat which causes a reaction in the egg whites creates a chemical reaction. When you take these simple components and create a complex reaction this is a prime example of a synthesis reaction.
What is it when 2 simple substances combine to form a new more complex substance?
This process is called a chemical reaction, where two simple substances (reactants) combine to form a new, more complex substance (product). Chemical bonds are broken and new bonds are formed during this process.
Why does benzocaine precipitate during neutralization?
Benzocaine is a weak acid that is only slightly soluble in water. During neutralization, the pH of the solution changes, which can cause benzocaine to become even less soluble and precipitate out of solution. This occurs because the neutralization disrupts the balance of ions and the solubility of benzocaine, leading to its precipitation.
