The answer is A because it cannot be B because that is ethylene and not D because it needs a subscript of 2 since it is a diatomic and it is no C because it is not carbon dioxide its oxygen
Protons and neutrons i think , sorry if i’m wrong.
Answer:
Animal? Bacteria? Plant? Fungi? What do these figures represent?
2
None of the above! These organisms may be single-celled like bacteria, and they may look like a fungus. They also may hunt for food like an animal or photosynthesize like a plant. And, yet, they do not fit into any of these groups. These organisms are protists!
What are Protists?
3
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.

Although Ernst Haeckel set up the Kingdom Protista in 1866, this kingdom was not accepted by the scientific world until the 1960s. These unique organisms can be so different from each other that sometimes Protista is called the “junk drawer" kingdom. Just like a junk drawer, which contains items that don't fit into any other category, this kingdom contains the eukaryotes that cannot be put into any other kingdom. Therefore, protists can seem very different from one another.

Hope it helps, some how.
For 1 mole of S₂O₃²⁻ 0.5 mole of S₂O₈²⁻ will be used.
<h3>What is a balanced Reaction ?</h3>
A reaction in which the number of atoms in reactants is equal to the number of atoms in the products is called a balanced reaction.
The reaction given in the question is
S₂O₈²⁻ + 2I⁻ ⇄ 2SO₄²⁻ + I₂
I₂ + 2S₂O₃²⁻ ⇄ 2I⁻ + S₄O₆²⁻
Adding the equation will give balance equation
S₂O₈²⁻ + 2I⁻ + 2S₂O₃²⁻ ⇄ 2SO₄²⁻ + 2I⁻ + S₄O₆²⁻
So x moles of S₂O₈²⁻ require 2x of S₂O₃²⁻
for 1 mole of S₂O₃²⁻ 0.5 mole of S₂O₈²⁻ will be used.
