Q: Explain the difference between iron(II) nitrate and iron (III) nitrate. What is the significance of the Roman numerals?: Iron exists in 2 forms called Ferrous and Ferric. The numeral 2 represents the valency of Ferrous iron and 3 represents the valency of Ferric iron. Valency is the ability to react. Ferrous nitrate has 2 nitrate radicals while Ferric nitrate has 3 nitrate radicals to a single atom of iron.

Q: Conair Spiraling Iron: It sounds like you have watter hammer. Probably the best way to cure this is to drain your home's plumbing system and when it is fully drained, re-open the main valve. What happened was probably the air chambers in your home's plumbing system have become watter logged, rendering them useless. This simple procedure should fix the problem. If this does not work, it's best to contact a plumber. Some homes were built without air chambers, and the plumber can install pressure arrestors which should control the problem. Chances are, this should not cost too much money. Hope this helps.

Q: Who would win and why?I say Iron Man!: Iron man has better gadgets than Batman. Iron Man got plenty of Full Body armors to go around.

Q: and why do some people have normal hemoglobin levels but iron deficiency?: no, i hope you are kidding. Actually if you bring helium to the pressure of 30-40psi you couldn't even tell. And just so you can say you learned something today, i fill my tires with nitrogen, the larger molecules leak out slower.

Q: just wondering this but where in the hell does iron from space come from??? i watched some show on the histroy channel about iron asteriods on how they could destroy earth but i did not hear on where the iron comes from. where in space?????: If the meteorite came from a large body, such as a shattered small planet, the body could have been large enough to have an iron-nickel core, like the earth (some of the very large meteors between Jupiter and Mars have iron cores). The body could have been shattered by colliding with another large body, when the solar system was still in the process of forming. If the meteorite came from the outer, rocky layer of the shattered body, it would be a stony meteorite. There is another, rarer type of meteorite called a carbonaceous chondrite; and these are believed to have formed early in the history of the solar system, and not to have formed later on.

Q: Like mostly every town in Upstate New York, we get well water.This means that some people have iron in their water, and some people have sulfur, which I‘m glad I don‘t have, because it smells like rotten eggs.Well, anyway, I have iron in my water. It doesn‘t smell or anything, you can‘t even notice you have it, really. So, what does iron do to your hair and your skin? I‘m very curious.: Iron usually occurs with manganese in water. Some iron and manganese is fine. Excessive amounts typically cause staining of clothes and encourage the growth of iron bacteria, which impart a foul taste and odor to the water. Typically, iron should not exceed 0.3 mg/L and manganese 0.05 mg/L in drinking water.

Q: doing a lab report and i need to know something common but BIG made out of iron: Well anything steel has iron in it

Q: What are some plant processes that involve iron? or how do plant cells use iron?: Plants use inorganic minerals for nutrition, whether grown in the field or in a container. Iron is one of the micro nutrients required by the plants. Iron is necessary for many enzyme functions and as a catalyst for the synthesis of chlorophyll. It is essential for the young growing parts of plants. Deficiencies are pale leaf color of young leaves followed by yellowing of leaves and large veins. Iron is lost by leaching and is held in the lower portions of the soil structure. Under conditions of high pH (alkaline) iron is rendered unavailable to plants. When soils are alkaline, iron may be abundant but unavailable. Applications of an acid nutrient formula containing iron chelates, held in soluble form, should correct the problem.
