### strong oxidizing agent:

Iodic acid
* is acid
  - chemical compounds
  - the only stable oxidizing halogen acid
  - used to make other iodates by reacting bases with iodic acid
* strong oxidizing agent.
* white solid that can dissolve in water to make an acidic solution.
+ Iodic acid, Properties: Iodine compounds :: Acids
  * Iodic acid is a white solid that can dissolve in water to make an acidic solution. Chloric acid and bromic acid only exist in solution and break down when crystallized. Iodic acid is a strong oxidizing agent. It can be converted to iodine pentoxide when it is heated gently. If it is heated strongly, it decomposes into iodine, oxygen, and other iodine oxides
  - Uses
  * Iodic acid is used to make other iodates by reacting bases with iodic acid. It is also used as a strong acid
+ Iodine, Properties, Chemical compounds: Halogens :: Chemical elements :: Nonmetals
  * Iodides are normally colorless but turn yellow after being in air because the iodide is oxidized to iodine. Iodides react with acidified manganese dioxide or chlorine to make iodine. Iodine monochloride is a red or brown liquid. Iodine trichloride, as well as iodine trifluoride, are yellow solids. Iodates like potassium iodate are colorless solids similar to chlorates. Iodic acid is the only stable oxidizing halogen acid. Chloric acid, by comparison, is very unstable and dangerous. Iodine pentoxide is a white solid, and iodine pentafluoride is a yellowish liquid. Periodates, like sodium periodate, are colorless solids similar to perchlorates, although weaker oxidizing agents. They decompose to iodates when they are heated. Periodic acid is not as stable as iodic acid.

### strong reducing agent:

Anhydrous hydrazine
* is available in monopropellant and standard grades.
* strong reducing agent.

### strong swimmers:

Mountain tapir
* Most mountain tapirs live in areas
  - mountain areas
* Some mountain tapirs have mountains.
* are strong swimmers
  - the smallest of the four species of tapir
* eat a variety of tough, fibrous leaves of shrubs.
* have the longest hair, about one inch.

### strong wood:

American elm
* Most american elms have distinctive shapes
* Some american elms grow in zones
  - have ciliate margins
* Some american elms have extensive natural ranges
* are elms
  - native to Saskatchewan and therefore ideally suited to our cold, harsh climate
* grow on the island in the middle of the lake.
* grows in full sun or part shade.
* has an extensive natural range
  - one of the most easily recognized tree silhouettes
* is found throughout South Dakota
  - highly vulnerable to Dutch elm disease
  - intermediate in tolerance to competition
  - native to the entire state of Iowa
* strong wood.

### stronger:

Sigma bond
* are strong and the electron sharing is maximum.
* can involve s, p, d or f orbitals.
  * It is the strongest one of the covalent type. In a sigma bond, the atomic orbitals from two atoms which are nearby go one on top of each other. This is different from a pi bond where they touch sideways. This is why a sigma bond is stronger. Sigma bonds can involve s, p, d or f orbitals. They must however be of the right symmetry to be able to form the bond.

### structurally similar:

Vertebrate eye
* All vertebrate eyes are structurally similar.
* Most vertebrate eyes have blind spots
