Write the chemical formula for the following acids using the common convention for acids (acidic hydrogens first).**Diagram 1:**- Structure: The diagram shows a molecule with two oxygen atoms double-bonded to a central carbon atom, each oxygen having two lone pairs of electrons. Two hydrogen atoms are single-bonded to the carbon on opposite sides.- Explanation: This is a linear arrangement with the carboxylic acid group (-COOH).- Molecular Formula: H₂CO₃**Diagram 2:**- Structure: The diagram shows a three-carbon chain. The first carbon is single-bonded to an oxygen, which is double-bonded to another oxygen (forming a carboxylic acid group). This carbon is also bonded to a second carbon, which is bonded to two hydrogen atoms. The second carbon is bonded to a third carbon, which is also bonded to two additional hydrogen atoms.- Explanation: This is a short carbon chain with one carboxylic acid group.- Molecular Formula: C₃H₆O₂**Diagram 3:**- Structure: The diagram displays a four-carbon chain. The first carbon is single-bonded to an oxygen, which is double-bonded to another oxygen (forming a carboxylic acid group), and to a second carbon. The second carbon is bonded to two hydrogen atoms and a third carbon, which is bonded to two more hydrogen atoms and a fourth carbon. The fourth carbon is bonded to two additional hydrogen atoms and a single-bonded oxygen with two lone pairs of electrons.- Explanation: This is a longer carbon chain with one carboxylic acid group and an additional oxygen group at the end.- Molecular Formula: C₄H₈O₃

Given molecules:The species which donates proton are termed as acids. The representation of a compound using atomic symbol with numerical subscripts to denote the number of atoms present in the compound or molecule is termed as chemical formula or molecular formula.Molecule 1 has 2 acidic hydrogen, molecule 2 has one acidic hydrogen due to presence of one carboxylic acid, and molecule 3 has 2 acidic hydrogen due to the presence of two -COOH group. Thus, the chemical formula for given molecules is represented as follows:Answer:
