Nitrite and Nitrate are compounds of the element Nitrogen, which makes up about 80 percent of the air we breathe. As an essential component of life, nitrogen is recycled continually by plants and animals, and is found in the cells of all living things. Organic nitrogen (nitrogen combined with carbon) is found in proteins and other compounds. Inorganic nitrogen may exist in the free state as a gas, as ammonia (when combined with hydrogen), or as nitrite or nitrate (when combined with oxygen). Nitrites and nitrates are produced naturally as part of the nitrogen cycle, when a bacteria 'production line' breaks down toxic ammonia wastes first into nitrite, and then into nitrate. Sources of nitrites and nitrates
Nitrites are relatively short-lived because they're quickly converted to nitrates by bacteria. Nitrites produce a serious illness (brown blood disease) in fish, even though they don't exist for very long in the environment. Nitrites also react directly with hemoglobin in human blood to produce methemoglobin, which destroys the ability of blood cells to transport oxygen. This condition is especially serious in babies under three months of age as it causes a condition known as methemoglobinemia or "blue baby" disease. Water with nitrite levels exceeding 1.0 mg/L should not be given to babies. Nitrite concentrations in drinking water seldom exceed 0.1 mg/L.
Nitrates stimulate the growth of plankton and water weeds that provide food for fish. This may increase the fish population. However, if algae grow too wildly, oxygen levels will be reduced and fish will die.
Furthermore, Even though ammonium nitrate cools water, the amount require to have any notable effect on a hurricane would be enormous, probably on the order of millions of tons. Such a large amount of the salt even if it could be deployed would probably do more damage than the hurricane.
it may kill many sea animals and it poisons the water.

No. It is a chemical change (chemical reaction) in which the products are different from the reactants. The balanced chemical equation is Cu(NO3)2+2NH4OH-->Cu(OH)2+2NH4NO3, which means one mole of copper(II) nitrate plus two moles of ammonium hydroxide produce one mole of copper(II) hydroxide plus two moles of ammonium nitrate.
When ammonium nitrate (NH4NO3) is mixed with water, the dissolution of ammonium nitrate occurs - that is, it is broken up into its ions. This is endothermic, and is the driving reaction behind instant cold packs.
No, it is a chemical change. Rearrangement of atoms to make different compounds is one way to define a chemical reaction.
No. A hurricane will not change its direction of rotation.
It is a chemical change because the ammonium dichromate changes color, explodes, and probably creates a gas during the change.
To my knowledge, a penny is not a chemical change. No, I think it is instead a coin; a unit of currency, mostly made from zinc and plated with copper. Nothing I'm describing has anything to do with chemical changes.
Unlike salt, potassium nitrate's chemical solubility is most affected by a change in temperature. Potassium nitrate is a chemical compound.
The appearance of chromium will not change if added to the sodium nitrate since it cannot displace nitrate from the sodium.
You cannot do that. You can only make sodium nitrate using a different process (search Youtube) or buy it.
No. The ammonium chloride is diluted by the water, so it's not as concentrated as before. The only time that it will be a chemical change will be when the ammonium chloride reacts with water, that is, IF it reacts with water.
