There are lots of variables.
1. relative humidity
2. dew point temperature
3. air temperature
4. wind speeds
5. vapor pressure
6. latitude and longitude
7. orrographic lift (surface type)
there are probably more, but hope this helped! :)
Answer:

Explanation:
Hello,
In this case, since 11 mg per kilogram of body weight has the given lethality, the mg that turn out lethal for a chicken weighting 3 kg is computed by using a rule of three:

Thus, we obtain:

That in grams is:

Answer:
I₂ + H₂O --------→ HI + HIO
Explanation:
Iodine is not fully dissolve in water but only dissolve up to some extent.
When iodine was mixed with water it give mixture of two products.
- Hydrogen iodide or hydroiodic acid (HI)
- Hypoiodous acid (HIO)
So the balance reaction is as under
I₂ + H₂O --------→ HI + HIO
All the reactant are one mole and one one mole of each product produced in the shown reaction.
This is a reversible reaction and only 0.05% of Iodine molecule react with water and the other Iodine molecule remain in water unreacted.
