A method used ti release iron metal from its ore involves----A.Heating the ore and carbon togetherB.Cooling the ore in an ice bathC. Breaking the ore into small piecesD.PanningHELP AND WHO EVER GIVES THE BEST AND MOST INFO WINS! and gets best answer of course
I would say 100 Miles of mixed riding. Just 100 miles of highway will only scrub the center of the tires and send you lowsiding with the first good lean. So mix it up, taking corners slow at first, then increasing in speed untill you are back where you were before.
I agree with Firestormer--it's not the miles, it's the lean angle. You want to rough up the surface you are apt to use. If you don't want to ride in circles, I suggest you take it easy in your daily riding then gradually and smoothly add more and more lean angle till you have leaned over about as far as you ever would in normal riding. Look at your tires and you'll see a lighter gray dullness in the center where you usually ride. That shiny blackness on the edges is still a bit slick. Add and take away lean angle SMOOTHLY. Ease that bike down to the apex. Don't throw it around like a toy--well, at least not until your tires are scuffed in and warmed up!
The answer is 'A'. You also need to 'ventilate' the heated ore to allow oxidation. Iron is produced in a Blast Furnace. Its released in molten form. Its not something you can do in the kitchen.
A C. The ore has Iron oxide in it. By heating the ore with carbon. The carbon is burned, but the only source for oxygen is the oxygen attached to the Iron oxide. The product of the reaction CO2 is a gas, you are left with pure iron. Breaking up the ore helps to speed the reaction. Exposing more surface area. Interesting side note. You start with a big pile of ore, and end up with a tiny amount of metal. This is where the term “reducing” came from. It is the way I remember redox type questions. The half reaction making the free metal is the “reduction” reaction.
A:Crushing the ore, then smelting using 2000* heat and separating the metal from the ore by sulphuric acid.then drying solution and collecting the metal in filters in the drying vatthen, collecting the metal, re-melting it and pouring into ingots.
