FranFormaldehyde absorbs light most strongly at a wavelength of around 412 nm due to its electronic structure. By using 412 nm in UV-Vis analysis, we can employ the maximum absorbance of formaldehyde to accurately quantify its concentration in a sample. This wavelength is chosen based on the specific molecular properties of formaldehyde that enable it to interact with light most effectively.

How do calculate the energy needed to break all the bonds in 1 mol of methane?
To calculate the energy needed to break all the bonds in 1 mol of methane, you would need to determine the total bond energy of all the bonds present in methane (CH4). Methane has 4 C-H bonds. The average bond energy for a C-H bond is approximately 413 kJ/mol. Thus, the total energy needed would be 4 * 413 kJ/mol = 1652 kJ/mol.
