Why is electrolysis needed to extract aluminum from its oxide?
The bond between the aluminum and its oxide is very strong. Aluminium is also high up in the reactivity series; using the displacement method requires highly reactive elements at high temperatures to extract the aluminum (not practical). You have to use electrolysis to extract aluminum because... Aluminium is higher than carbon in the reatvity series where carbon reduces the oxide from zinc iron tin etc.... so you need to use electrolysis to remove the oxygen from the aluminum ore. Hoped this help :)
How is iron made from iron oxide?
Using a blast furnace. Iron ore is poured into a blast furnace which is heated to several thousand degrees Celsius, carbon is added to react with the oxygen and form carbon dioxide, other elements such as magnesium are added to react with impurities such as sulphur. Once the purification is complete a layer of all the impurities forms on top which is called slag. Remember, the slag always goes on top.
What is the net ionic equation for carbon dioxide gas when it is passed over hot solid sodium oxide?
The net ionic equation for this reaction is: CO2(g) + 2Na2O(s) -> 2Na2CO3(s)
Does titanium react with hydrocloric acid?
No, not at room temperature. It does react with hot hydrochloric acid to form a complex ion with the titanium in the +3 oxidation state but this is not the standard Metal + Acid -> Salt + Hydrogen reaction of more reactive metals
How are sulfur dioxide carbon monoxide and nitrogen oxide produced in combustion?
Sulfur and carbon are oxidized during the combustion process. Sulfur normally forms two compounds when it burns, Sulfur dioxide and to a lesser extent sulfur trioxide. This is normal. Carbon when it burns produces carbon dioxide, if there is not enough air provided to the combustion it will produce carbon monoxide, which is an incomplete reaction. Carbon monoxide is combustible gas and can be burned further into carbon dioxide, with the proper application of air. Nitrogen oxides, nitrous and nitric oxide, are a separate process. These chemical bonds require a heat input to form, and rob heat from a fuel. Typically they are not formed at temperatures under 1500F (816C). These compounds are formed from nitrogen in either the fuel or the air, a very hot flame is required to produce them.
How do you extract aluminium from Aluminium Oxide?
By Electrolysis. Aluminium is too reactive a metal and too high in the reactivity series to be reduced by carbon reduction. The method is to dissolve aluminium oxide in cryolite(a temperature reducing catalyst). An electrical charge is put across the mixture Whereupon the aluminium oxide forms the cation Al^(3+) and the oxygen forms the oxide anion (O^(2-) The aluminium cation moves to the cathode and received electrons from the electrical charge at the cathode to form aluminium metal. Correspondingly thre oxide anion moves to the anode and forms oxygen. However, because of the high electrical amperage , the anions if very hot , and made of carbon, so the oxygen reacts with the anode nnd forms carbon dioxide, which the released gas. Have a look and the Royal Society of Chemistry's video on this industrial process.
What is the word equation for the production of tin by smelting tin oxide with hot carbon?
google it mc 4=asfsd + go on google and type it in mcsquared
Does calcuim oxide react with cold water?
Yes it does react. It forms Calcium hydroxide and makes the water hot. It is because the reaction between CaO and water is an exothermic reaction
Why aluminum does not react with cold water?
Aluminum forms a protective oxide layer on its surface when exposed to air or water, which prevents further reaction with water. This oxide layer acts as a barrier, preventing the aluminum underneath from reacting with water. Additionally, aluminum is relatively low on the reactivity series, so it does not readily react with water, especially at cold temperatures.
How can the carbon dioxide produced when these fuels are burned influence climate?
put ur penis on hot burner then it will produce carbon di oxide
Does oxygen react with hot copper?
Yes, it rapidly forms a layer of blue green copper oxide on the copper surface.

What conditions favor rust?
amazingy the answer is hot humid cimates where the oxide can react with the outside pluatrian of the metal which will start the rust to form.
What is the reaction of carbon with hot nitric acid?
Carbon does not react with hot nitric acid due to its inert nature. The oxidation state of carbon in hydrocarbons is generally lower than its highest oxidation state (+4), which is needed for reaction with nitric acid. Thus, carbon remains unreactive towards hot nitric acid.
What is the colour of lead oxide when hot and cold?
Lead oxide is yellow when hot and reddish-brown when cold.
What is the formula for dry ice?
The dry ice is the solid form of the Carbon Dioxide (CO2) so you can name it: Carbonic anhydride, Carbonic acid gas, Carbon oxide, Carbonic oxide, Carbon(IV) oxide, and also as you called it, Dry ice (solid phase).
Why is it when a piece of copper is folded squashed and heated in air only the outside of the copper is black?
The black coating you see is a coating of copper oxide, which forms when the hot metal reacts with air. no air can reach the inside, so it does not react to form black copper oxide.
