For the answer to the question above, t<span>he energy that is required to break all the carbon-hydrogen bonds in methane is 891 kJ/mol. In 0.1 mol of methane, you would need 89.1 kJ.
I hope my answer helped you. Have a nice day</span>
Answer:
It represents the <em>number of atoms</em> of that particular element present in the compound. In C₂H₄O₂ there are 2 Carbon atoms, 4 Hydrogen atoms and 2 Oxygen atoms.
The error in the student's reasoning happened as they get confused between the beta minus decay and beta plus decay.
<h3>What is beta minus decay?</h3>
A neutron is converted into a proton in beta minus, increasing the atomic number of the atom.
- The proton is positive, while the neutron is neutral.
- The nucleus also produces an electron and an antineutrino in order to ensure charge conservation.
In the given question beta minus decay is not occur as atomic number of the daughter nuclei does not increases. Rather than this in the given decay atomic mass of the daughter nuclei is less than the parent nuclei means plus beta decay is happened there.
Hence the error is in predicting the correct particle with charge.
