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: The following have all been scratched to expose the iron.1. An iron strip coated in plastic2.An iron strip coated in zinc3. An iron strip coated in tin4. An iron strip coated in paintAll are in a salt solution - which would rust quickly?: thomas is wrong. iron + tin will rust quickly. it is due to the reason that iron is more reactive than tin and when tin react with salt,it also gets displaced by iron as iron is more reactive. and plastic is a stable compound,so it will not react.same is for paint.and zinc is more reactive than iron.so zinc will displace iron form its compound made by reaction of salt and ironso it will not rust, thus,,,,most reactive is iron +tin any other problem dude?

Q: why do we need alloys of iron?is it linked to the properties of iron metal?: iron is a very strong metal.very desirable in industrial application,sa main part of steel.also one of the only metal,s that can be magnetizedpermanently.

Q: My mum has just been to the doctor and they said she has extremely low iron levels.She doesnt smoke, drink alcohol, do drugs or eat unhealthily.What are some of the things that would cause such low levels of iron?Thanks! :): Not consuming enough Iron would cause Anemia (low Iron levels). Try to include more red meat in her diet. She needs to compensate for all the iron and blood she loses during her Menstrual Cycle, which is why Women are susceptible to having low Iron.

Q: Like, how did it affect the Mycenaean‘s and other kingdoms, besides that their tools were made out of iron. Thankss!: Those with iron weaponry could defeat their enemies more readily than those without. This civilization existed at the beginning of the iron age. Those who had bronze weapons could not compete on the battlefield. Those with iron weapons had two things going for them: a source of iron and (likely secret) knowledge as to how to smelt the ore to produce iron weapons and other utensils.

Q: what are the symptoms of a dog overdosing on iron?: Iron toxicity can cause stomach irritation or possibly perforation. Iron can also cause liver or kidney failure. Signs would be blood diarrhea, or dark/bloody urine.

Q: food that contains iron: Kids should eat two or three iron-rich foods a day, adults at least one * liver * lean red meats, including beef, pork, lamb * seafood, such as oysters, clams, tuna, salmon, and shrimp, etc. * beans, including kidney, lima, navy, black, pinto, soy beans, and lentils * iron fortified whole grains, including cereals, breads, rice, and pasta * greens, including collard greens, kale, mustard greens, spinach, and turnip greens * tofu * vegetables, including broccoli, swiss chard, asparagus, parsley, watercress, brussel sprouts * chicken and turkey * blackstrap molasses * nuts * egg yolks * dried fruits, such as raisins, prunes, dates and apricots

Q: Alright I'm doing a project on electrolysis and as much as I try i just don't understand it.My anode cathode are both IronMy solution is Fe(No3)2 which is Iron (II) NitrateI need to talk about what happens and why the mass of the anode decreases but the mass of the cathode increases.I've got some crazy theory but i don't know if its correct or not so if anyone could clarfiy that would be great.Thankyou so much! :): Anode: Oxidation Iron becomes Iron(II) it dissolves in water, so the Anode loses mass. Cathode: Reduction Iron(II) becomes Iron and accumulates itself at the Cathode which gains mass. Oxidation means to dispense electrons, this electrons are transported through a wire to the Cathode. At the Cathode electrons are given to Iron(II) that were dissolved in water. If it is is still unclear i can try to explain it better
