I dont know sorry but good luck i know u can past
The electron configuration for a neutral atom of oxygen would be the final option:
O : 1s^2 2s^2 2p^4.
Knowing that this is a neutral atom of oxygen, and that it posses the same number of electrons and protons, the total number of electrons would be 8. Which can be found out by adding the exponents for each subshell.
Answer: Stochiometric coefficients
Explanation: The chemical equations must be balanced to follow the law of conservation of mass which says that the mass of products must be same as the mass of reactants.
![CH_4+O_2\rightarrow CO_2+H_2O](https://tex.z-dn.net/?f=CH_4%2BO_2%5Crightarrow%20CO_2%2BH_2O)
This is a skeletal equation and needs to be balanced by adjusting the stochiometric coefficients. In order to keep the mass same, the number of atoms must be same on both sides.
![CH_4+2O_2\rightarrow CO_2+2H_2O](https://tex.z-dn.net/?f=CH_4%2B2O_2%5Crightarrow%20CO_2%2B2H_2O)
The individual is most likely sifting through the debris which is found at the crime scene.
<h3>What is Debris?</h3>
This is defined as the scattered remains of something which has been broken down as a result of incidents such as an explosion.
The wire mesh is used as it helps to remove long fibers present at the crime scene which is taken for investigation.
