Answer:
Option 1, Cl is reduced and gains electrons
Explanation:
HClO₃ → HClO₂
In HClO₃, chlorine acts with +5 in the oxidation state
In HClO₂,, chlorine acts with +3 in the oxidation state.
The state has been reducted, so the Cl has been reduced. As it was reduced, it means that has won e⁻, in this case 2
Cl⁻⁵ → Cl⁻³ + 2e⁻
Hi there! Let's tackle this together.
The answer to the question is option A.

The answer is option A.
Answer:
a.draw 2,3 dicholoro octane
Explanation:
mag isip ka kung paano hehe
<span>Solving for the formula mass of calcium nitrate:
Atom | Atomic Mass
Ca | 1 x 40.08 = 40.08
N | 2 x 14.01 = 28.02
O | 6 x 16 = 96
FM = 164.10 amu
Solving for the percent:
%O2 = mass of oxygen / mass of compound x 100%
%O2 = 96 amu / 164.10 amu x 100%
%O2 = 58.50% or 59%</span>
