select the model of a molecule composed of one carbon atom, two hydrogen atoms, and two oxygen atoms.\nwhat is the chemical formula for the substance composed of these molecules?

select the model of a molecule composed of one carbon atom, two hydrogen atoms, and two oxygen atoms.\nwhat is the chemical formula for the substance composed of these molecules?

Answer

Explanation:

Step1: Analyze atom - counts in each molecule

Formic acid has 1 carbon (C), 2 hydrogen (H), and 2 oxygen (O) atoms. Methanol has 1 carbon, 4 hydrogen, and 1 oxygen atom. Ethenol has 2 carbons, 4 hydrogens, and 1 oxygen atom.

Step2: Determine the correct molecule

The molecule with 1 C, 2 H, and 2 O atoms is formic acid.

Step3: Write the chemical formula

The chemical formula for a molecule with 1 carbon, 2 hydrogen, and 2 oxygen atoms is $CH_{2}O_{2}$.

Answer:

First question: formic acid Second question: $CH_{2}O_{2}$
