What is the metal that can be used to reduce aluminium ore to a metal why is this reaction not done in practice?
There are a number of metals which can reduce aluminum (I am using the word reduce in the chemical sense, meaning to donate electrons to another element) which include lithium or sodium. This is not done in practice because it is not an economical way of making aluminum. You can make it much more cheaply by using electricity to drive the reaction.
Can you use an aluminium wire instead of copper for a simple electrical circuit?
Yes, you can use an aluminum wire. Aluminum does conduct electricity. However, there is a well-known problem with aluminum wire. When exposed to air, the outer layer of aluminum forms a non-conductive oxide. There is resistance to the flow of electricity as it attempts to get through the aluminum oxide coating to the conductive aluminum below. When aluminum wire is used to reduce weight, it is usually welded to another metal that makes a better contact, such as copper. The contact metal is then what is connected.
Why is hydrogen able to reduce copper oxide but unable to reduce magnesium oxide?
because copper is located below hydrogen in reactivity series, thus hydrogen can reduce copper oxide which mean it undergo reduction reaction (loss of oxygen) CuO + H2 → Cu + H2O while, hydogen can't reduce magnesium because magnesium is located higher than hydrogen in reactvity series. it must be added with oxygen which mean it undergo oxidation reaction (gain oxygen) 2Mg + O2 → 2MgO i hope this will help u a lot ^_^
What happens when a silver piece of zinc is placed in a blue solution of copper ii nitrate?
The silver piece of zinc dissolves forming zinc ions. Copper(ii) reduce into copper(i) ions. The blue color of the solution decreases.
How Benedict's solution react with sugar?
Sugar donates electrons that reduce blue copper (II) sulfate to orange copper (I) oxide.
What scientific conclusion can be made about combining Copper Chloride and Aluminum Foil?
The two are highly reactive when mixed in water. If you add aluminum to a water solution of copper chloride, the aluminum will be combined as aluminum chloride gas, releasing the copper into the water. The mixture will turn very hot, bubble up, and start to smoke, and the color will change from blue to dark red. ========================= The first sentence is correct, the two are highly reactive, but from there on, there are problems... There's no such thing as aluminum chloride gas. There is a gas given off, but it is hydrogen gas. The "smoke" is actually tiny droplets of water condensed from water vapor. It gets that hot. The red color is due to the formation of copper metal a Cu2+ ions are reduced to the metal as aluminum metal is oxidized. Aluminum metal has a thin coating of aluminum oxide, Al2O3, covering the surface. Even freshly scraped aluminum metal will quickly reform the passivating layer of aluminum oxide. So in many solutions, the layer of Al2O3 prevents any aluminum metal from reacting. If aluminum metal is placed in a solution of copper(II) sulfate, you will not get a reaction. No copper metal will form on the aluminum. But when placed in copper(II) chloride, aluminum will give a vigorous reaction with a lot of heat and hydrogen gas being given off. The reason is the chloride ion. In the presence of chloride ion, the Al2O3 layer dissolves forming the AlCl4^- in solution and exposing a fresh layer of aluminum metal. The aluminum metal will reduce copper(II) ions to copper metal, AND the aluminum metal will react with water very much like an alkali metal reacts with water, vigorously, with a lot of heat given off, and with the formation of hydrogen gas. Al2O3 + 8Cl- + 3H2O --> 2AlCl4^- + 6OH- Al(s) + OH- + 2H2O --> Al(OH)3(s) + H2(g) 2Al(s) + 3Cu2+ --> 2Al3+ + 3Cu(s)
What is the name of AlCl3?
AlCl3 is used in paint,detergent manufacturing and petroleum refining..
How is copper losses reduced in transformers?
how to reduce copper losses in a transformer Copper losses are due to the resistance of the copper (or aluminum) windings. To reduce copper losses the transformer would have to be rewound with heavier gage wire.
What change is expected in the reaction mixture if a copper wire is kept immersed in AN Iron sulphate solution?
No reaction, because iron is a more active metal than copper. This means that copper cannot reduce iron from its salt.

Does copper chloride produce hydrogen?
Copper Chloride (CuCl2) would have to react with another compound in order for it to produce hydrogen.Added:Cu2+ will never produce hydrogen because it can not REDUCE at all, only oxidize another substance.To 'make' hydrogen it is necessary to extract electrons from a reductant (= electron donor). Copper metal (Cu) would be able to do to H+ ions (from strong acids).
