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.
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.
Why oxides of high reactive metals cannot be reduced by carbon?
Except through electrolysis a metal in an oxide can only be replaced by a more reactive metal. If fact that is one of the measure of reactivity. Highly reactive metals such as magnesium are actually stronger reducing agents than carbon, so rather than carbon reducing their oxide, they will reduce oxides of carbon.
Are alkaline-earth metals reactive?
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
Can you burn metals to make metal oxides?
Yes, many of the more reactive metals can be burnt to produce their oxides. Magnesium is a good example of this which burns with a white light to produce MgO. Not all metals need to be burnt. Iron is oxidised by oxygenated water to form Iron oxide (rust) and aluminum is oxidised in air. Less reactive metals however, will need different conditions to be oxidised. The least reactive metals such as platinum and rhodium are very difficult to oxidise.

Fairly reactive metals found as ores?
Sodium, magnesium, and aluminum are examples of fairly reactive metals that are commonly found as ores in the Earth's crust. These metals can be extracted from their ores through processes such as electrolysis or chemical reactions.

Highly reactive metals such as magnesium are actually stronger reducing agents than carbon, so rather than carbon reducing their oxide, they will reduce oxides of carbon.
Why is carbon reduction process not applicable for reduction of oxides of metals like Mn and Cr?
The carbon reduction process is not applicable for reducing oxides of metals like Mn and Cr because these metals have a higher affinity for oxygen than carbon. As a result, they are not easily reduced by carbon at typical temperatures. Alternative methods, such as using more reactive reducing agents or employing higher temperatures, are often required to reduce oxides of metals like Mn and Cr.
Are alkaline-earth metals reactive?
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
Where do you put aluminum in the reactivity series?
Aluminum is placed above carbon in the reactivity series, meaning it is more reactive than carbon. It reacts with acids to release hydrogen gas and with metal oxides to produce metals. However, it is less reactive than metals like sodium and potassium.
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).

Yes, many of the more reactive metals can be burnt to produce their oxides. Magnesium is a good example of this which burns with a white light to produce MgO. Not all metals need to be burnt.

The least reactive metals such as platinum and rhodium are very difficult to oxidise.
What metal oxides can be converted to the metal by carbon reduction but not by hydrogen reduction?
any metals below carbon in the reactivity series. :)
What type of oxides are formed when non metals combine with oxygen?
Non-metals typically form acidic oxides when they combine with oxygen. These acidic oxides can react with water to form acids. Examples include carbon dioxide (CO2) and sulfur dioxide (SO2).
Is carbon dioxide an acidic gas?
Yes it is. All the oxides of non-metals are acidic and oxides of metals are basic
