How are metals less reactive than carbon extracted?
Metals are less reactive than carbon, so they are commonly extracted using reduction reactions. This involves using a more reactive substance, like carbon or a metal, to remove oxygen from the metal ore, leaving behind the pure metal. The reduction process helps to separate the metal from its ore efficiently.
What method is used to extract metals that are above carbon in the reactivity series?
Metals that are above carbon in the reactivity series are often extracted through electrolysis, a process that uses electricity to break down the metal compound into its pure form. This method is necessary because these metals are too reactive to be extracted using carbon reduction methods like smelting.
How are the very reactive metals high up in the reactivity series extracted from their ores?
Very reactive metals high up in the reactivity series, like sodium and potassium, are extracted from their ores through electrolysis. The metal ions in the ore are reduced at the cathode, while oxidation occurs at the anode. This process is energy-intensive due to the high reactivity of these metals.
What two processes are used to extract metals?
Two processes used to extract metals are pyrometallurgy, which involves high-temperature processes such as smelting, and hydrometallurgy, which involves using aqueous solutions to extract metals from ores.
Which elements is most reactive alkali metals or alkali earth metal or carbon family or inert gases?
alkali metals

The reduction process helps to separate the metal from its ore efficiently.
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.
Which elements cannot be extracted by heating with carbon?
Elements that cannot be extracted by heating with carbon include those that are more reactive than carbon, such as the alkali metals and alkaline earth metals. These elements require more powerful reducing agents for extraction, such as electrolysis.
Which metal is less reactive than sodium but cannot be extracted heating with carbon in a furnace?
Copper is less reactive than sodium but cannot be extracted by heating with carbon in a furnace due to its position in the reactivity series. Instead, copper is typically extracted using electrolysis or by reduction with more reactive metals such as iron.
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.
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.
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.
How are minerals extracted from their ores?
metals are extracted from their ores according to their reactivity series.firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.secondly, metals that are less reactive than carbon are extracted by reduction in which carbon is added to the metal ore, carbon react with oxygen and the metal remain by itself pure.example: Zinc oxide + Carbon ----> Zinc + Carbon dioxideGold and Platinum are found in nature by themselves.
