1) in periodic acid (HIO₄), iodine has oxidation number +7, hydrogen has oxidation number +1, oxygen has -2, compound has neutral charge:
+1 + x + 4 · (-2) = 0.
x = +7.
2) in molecule of iodine (I₂), iodine has oxidation number 0, because iodine is nonpolar molecule.
3) in sodium iodide (NaI), iodine has oxidation number -1, sodium has oxidation number +1:
+1 + x = 0.
x = -1.
4) in iodic acid (HIO₃), iodine has oxidation number +5, hydrogen has oxidation number +1, oxygen has -2, compound has neutral charge:
+1 + x + 3 · (-2) = 0.
x = +5.

Answer:
<h2>36.09 L</h2>
Explanation:
The initial volume can be found by using the formula for Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume.
Since we're finding the initial volume

We have

We have the final answer as
<h3>36.09 L</h3>
Hope this helps you
Scientists make hypothesis in order to make an educated guess on the outcome of the experiment.
Answer:
1,081.1 units of heparin should be given to 298 lb person.
Explanation:
We are given:
Weight of the person = 298 lb = 135.143 kg
Conversion factor used:
1 lb = 0.4535 kg
Number of unit of heparin to be given in an hour = 8.0 units/kg
Number of units given to the patient weighing 135.143 kg :

1,081.1 units of heparin should be given to 298 lb person.
