Answer: <span>Chlorine is losing electrons and being oxidized.
Justification:
1) Chlorine is losing electrons
As you se the side of the products shwo two electrons, that means that those electons were lost by the reactants. Given that the only reactant is chlorine, it is releasing or losing those electrons.
2) Chlorine is being oxidized.
The substance that loses electrons and, hence, increases its oxidation number, is the substance being oxidized.
In this case Cl (-) in the side of the reactants has oxidation state (1-), while Cl2 in the side of the products has oxidation state 0. This shows that the oxidation state of chlorine increased, meaning that it is being oxidized.

The answer for the following problem is explained below.
- <u><em>Therefore 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.</em></u>
Explanation:
Given:
mass of methane = 6.00 × 10^-3 grams
+ → +
Firstly balance the following equation:
Before balancing the equation:
→
After balancing the equation:
→
where;
represents methane molecule
represents oxygen molecule
represents carbon dioxide molecule
represents water molecule
+2 → + 2
16 grams of methane → 44 grams of carbon dioxide
6 × 10^-3 grams of methane → ?
=
= 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.
<u><em>Therefore 16.5 × 10^-3 grams of carbon dioxide is produced from the complete combustion.</em></u>
Your answer would be b )

Fe is the element Iron, the 2+ is how many electrons is lost to make the ion, so 2 electrons are lost from the valence shell (to make a full outermost shell)
Carbon, hydrogen should be the answer
