How Iron and Steel Work
The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface. Impurities, including carbon, are oxidized and float out of the iron into the slag. When the carbon content is right, you have carbon steel.

What happens when acid reacts with limestone? | Science …
— Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more …
Why does burning coal generate more CO2 than oil or gas?
— Coal contains more carbon than oil or gas. When we burn these fuels, the higher amount of carbon in coal reacts to form CO 2, while a higher proportion of hydrogen in oil and gas causes them to form H 2 O along with CO 2.. December 16, 2022. All living things are made mostly of carbon-based molecules—so fossil fuels, which are made of …
