A species whose oxidation number increases in a reaction is oxidized (reducing reagents or reactant).
For example, balanced chemical
reaction: 2KClO₃ → 2KCl + 3O₂<span>.
</span><span>Oxygen in the
reactant state has oxidation number -2 (+1 + 5 + 3 · x = 0) and it is
oxidized to 0 (in molecule of oxygen) in the product state.</span>
Wheres the diagram
We have to see the diagram to answer your question
Energy from a light source is known as radiation.
Answer:
1 200 000 000 000 000 000 000 000 H⁺ ions
Step-by-step explanation:
Assume that the concentration of H⁺ ions in stomach ions is <em>2.0 mol·L⁻¹.</em>
Then, we have 2.0 mol of H⁺ ions
There are 6.02 × 10²³ H⁺ ions in 1 mol.
2.0 mol = 2.0 × 6.022 × 10²³/1
= 1.2 × 10²⁴ H⁺ ions
= 1 200 000 000 000 000 000 000 000 H⁺ ions
