Answer: I2 is the Oxidant; while the 2S2O3(-2) is the reductant.
Explanation:
An Oxidant is any substance that oxidizes, or receives electrons from, another; in so doing, it becomes reduced in oxidation number.
A Reductant thus exactly the opposite.
Note that the equation provided shows that Iodine (I2) received an electron to become NEGATIVELY CHARGED:
I2 --> 2I-.
The oxidation number reduced from 0 to -1.
In contrast, the oxidation number of 2S2O3(-2) increases from -4 to -2.
Thus, I2 is the Oxidant; while the 2S2O3(-2) is the reductant.
A kilogram is a measure of mass; 1,000 grams
Answer:
it is called an ion
Explanation:
if it gains electrons then it is an anion
if it gains protons it is a cation
typically non metals are anions and metals are cations
Answer:
The second ring in an atom can only hold up to 8 electrons.
