What are the Fairly reactive metals found as ores compounds often oxides and carbonates and can be extracted using carbon to reduce the metal compound to the pure metal?
Fairly reactive metals such as iron, lead, and zinc are commonly found as ores in the form of oxides and carbonates. These metals can be extracted using carbon as a reducing agent to convert the metal oxides or carbonates into pure metals through a process called smelting. This method involves heating the ore with carbon in a furnace to produce the desired metal.
What metals can be extracted from their oxides using carbon?
Metals that are less reactive than carbon in the reactivity series, such as iron, lead, and copper, can be extracted from their oxides using carbon. The carbon reduces the metal oxide to the metal in a process known as reduction.
Are sulfur carbon and oxygen oxides?
Yes, sulfur, carbon, and oxygen can form oxides. Sulfur oxides (such as sulfur dioxide and sulfur trioxide), carbon oxides (such as carbon monoxide and carbon dioxide), and oxygen oxides (such as ozone) are all compounds formed by the combination of these elements with oxygen.
How are metals that are less reactive than carbon extracted from their oxides?
Metals less reactive than carbon, such as copper and silver, are extracted by reduction using carbon as a reducing agent. The metal oxide is heated with carbon (in the form of coke) to form carbon monoxide, which then reduces the metal oxide to the pure metal and carbon dioxide.
Why cant carbon be used to extract aluminium from its ore?
Aluminium cannot be extracted by reduction with carbon as aluminium is more reactive than the carbon. Instead electolysis must be used, which is a much more expensive method of extracting a metal from it's ore.

What are the types of oxides?
Examples: uranium oxides, sodium oxides, lead oxides, aluminium oxide, plutonium oxides etc.
What are neutral oxides of carbon?
The oxides of carbon are CO and CO2.

Which metal oxides will not react with carbon?
Noble metal oxides such as gold oxide (Au2O3) and platinum oxide (PtO2) typically do not react with carbon, as they are relatively inert under standard conditions. Other examples include silver oxide (Ag2O) and copper(I) oxide (Cu2O).
Ruby and sapphire are oxides of?
Ruby and sapphire are oxides of aluminum. They are both forms of the mineral corundum, with ruby being red in color due to the presence of chromium and sapphire coming in various colors, with blue being the most common, due to the presence of iron and titanium.
How can you separate aluminium hydroxide and iron oxide?
If the iron oxide is Fe3O4 you can use a magnet.This is possible because magnetite has strong magnetic properties.For the separation from other iron oxides aluminium hydroxide can be dissolved in alkalis; iron oxides are not soluble in alkalis.
What are the names and chemical formulas of the two most common forms of carbon found in the atmosphere?
The most common state of oxygen is probably oxygen combined with metals and silicon such as molecules of silica which is sand and molecules of metal oxides like iron oxide. Aluminium oxides and Iron oxides and many other metal oxides make up most of the rocks and heavy material in the earth's crust. The sea contains a lot of oxygen as H2O which is water and the air is 20% oxygen, but the earth's crust weighs a lot more than the oceans and the air put together. Therefore it is very likely that the rocky oxides hold most of the Earth's oxygen.
The process in which compounds are converted to oxides by heating them in the air is called?
roasting
