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: iron i believe come from meteor that enter our system.: Iron is an abundant element on earth. Some Iron meteors land on earth, Iron is abundant in the universe. All Iron on earth is not from meteors. Yours: Grumpy

Q: So I am trying to increase my iron levels as I have to give blood soon. Well I picked up an iron supplement and I took one. Well I just realized that it has 65 mg of iron in one pill. Why would they sell these if toxicity is over 50mg. Am I gonna be okay?: It is great that you are giving blood. However, unless you are suffering from iron deficiency anemia, no amount of iron is going to increase your hemoglobin count. You could take iron after the event, to speed up recovery, but most people do not have a problem in getting back to a normal level. 65mg of elemental iron ( usually in salt of iron about 300mg ) is the treatment dose for simple anemia. Toxic levels for an adult male start at about 700mg of elemental iron daily. If your hemoglobin level is normal, you need no more than 20mg daily for good health. Plenty of foods contain iron including green vegetables and liver

Q: The iron in harvest blend honey frosted corn wheat flakes with rolled oats granola clusters?: Iron is used in many processes in the body but usually the one you hear most about is that it is needed to build red blood cells which are used to carry oxygen.

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?????: Depends on your view on the state of the enviouroment

Q: What does the existence of iron-rich rocks during the Precambrian indicate about the evolution of Earth‘s atmosphere?: the precambrian represents a VERY VERY large chunk of time. it is everything before about 540 million years ago. if earth is 4.6 billion years old, thats means the pC lasted about 4.1 billion years. there was not always abundant oxygen on earth. in fact, earth was very anoxic, and oxygen was a nasty, poisonous byproduct to the earliest entities of life. about 2 billion years ago, halfway through the pC, the first photosynthetic bacteria start pumping the O2 out into the ocean. iron in the seawater quickly reacted with any new oxygen to form that characteristic rust-colored iron oxide, Fe2O3. the iron minerals quickly fell out of suspension, causing the notorious banded iron formations (BIFS) however, since there was a limited amount of iron and an exponentially increasing amount of free oxygen, eventually that chemical sink was used up and O2 was able to accumulate. organisms at the time either had to adapt to being tolerant of oxygen, die off, or take refuge (e.g. the organisms that now live by deep ocean thermal vents). so, for your answer, we really only see iron-rich rocks during the later half of the precambrian. it documents a time where the oxygen produced was being locked up into iron-oxide minerals instead of accumulating in the ocean (and thus the atmosphere because of mixing). it was only once all the iron was oxidized that the O2 crisis set in and free oxygen began to accumulate.

Q: if you only eat oatmeal ,bacon,and eggs for morning and nothing else with iron in it the rest of the day is this enough iron in the bacon,eggs,and oatmeal for the day?: You need to be careful about eating to much bacon and eggs because of cholesterol.
