What is formed when copper oxide is heated in a test tube with carbon?
When copper oxide is heated in a test tube with carbon, carbon acts as a reducing agent and reacts with copper oxide to form copper metal and carbon dioxide. This is a type of redox reaction where copper gains electrons from carbon, resulting in the reduction of copper oxide to copper.
Why is copper wire better conductor of electricity than a rubber tube is?
In rubber electrons cannot freely move among atoms as in copper.
What material used in boiler tube in indian power plant?
Usually Alloy steel is used, copper and brass are also used as boiler tube materials
Can you light a light bulb by holding a copper tube and a steel tube wired to a light bulb?
Yes, you can create a simple battery by holding a copper tube and a steel tube in an acidic solution like lemon juice, which will generate a small electric current. By wiring this to a light bulb, you can light it up. This experiment demonstrates the principles of making a battery using dissimilar metals.
What shrinks as it grows?
A balloon shrinks as it grows because its walls expand to accommodate the increasing amount of air inside.
What are the classification of a copper tube?
Copper tube is a favorite choice for plumbing, heating, cooling and other systems. Copper tube is most often used for supply of hot and cold tap water as refrigerant line in HVAC systems. There are two basic types of copper tube, soft copper and rigid copper. Copper tubing is joined using flare connection, compression connection, or solder. Copper offers a high level of corrosion resistance, but is becoming very costly. alliedallcityinc.com
What observation can be seen in a combustion tube when hydrogen gas is passed over heated copper II oxide?
When hydrogen gas is passed over heated copper II oxide in a combustion tube, the copper II oxide will be reduced, resulting in the formation of copper metal and water. The color change from black (copper II oxide) to brown (copper metal) can be observed in the tube, along with the release of steam.
What copper tube is available when using the grooved method of joining?
Grooved method? Threads on the end of the pipe? There is no tube or pipe in copper with threads. You can end a copper pipe with a connection that is threaded to accept steel pipe.
When a magnet is dropped inside a copper tube its exit is delayed by a few minutes why?
When a magnet is dropped into a copper tube, the changing magnetic field induces an electrical current in the copper tube. This induced current creates a magnetic field that opposes the motion of the magnet, causing it to slow down and take longer to exit the tube due to electromagnetic induction effects. This phenomenon is known as Lenz's Law.
What happens to color of copper suphate crystals when heated in a test tube?
The dehydrated copper sulfate is grayish-white.
Do you have to replace the copper pipes when replacing ac unit?
no need to change the copper tube if the capacity of the unit is same.
What is the function of capillary tube?
The capillary tube is used on the inside of the refrigerators. It is a long copper tubing that is used as a thruster.
What is formed when copper oxide is heated in a test tube with carbon?
When copper oxide is heated in a test tube with carbon, carbon acts as a reducing agent and reacts with copper oxide to form copper metal and carbon dioxide. This is a type of redox reaction where copper gains electrons from carbon, resulting in the reduction of copper oxide to copper.
What is the blood red residue formed in a glass test tube when copper carbonate is heated vigourously with carbon?
Elemental copper.
Where can one buy copper sheet for cheap?
Basic copper is an online site were you can get copper sheet. And you should probally would be able to get it from Metalsorce they are selling waste from a large metal company.
Heat CuCO3 in test tube and put the end of the tube from the test tube in limewater. what is the substance left in the test tube with the CuCO3?
When you heat CuCO3 (copper carbonate) in a test tube, it decomposes into copper oxide (CuO), carbon dioxide (CO2), and oxygen. The substance left in the test tube after the reaction is copper oxide (CuO). Copper oxide does not react with limewater, so you will not see any further reaction when the end of the tube is placed in limewater.
Why is copper wire better conductor of electricity than a rubber tube is?
In rubber electrons cannot freely move among atoms as in copper.
