pls mark me as brainliest. i just want 1 more brainliest answer. pls help
1. Since Iron is more reactive than copper, that means it has a greater tendency to lose electrons and form positive ion, displacing copper ion in copper sulphate solution. ... The reaction between copper and ferrous sulfate will not occur because copper is less reactive than iron.
2. Galvanising is a method of rust prevention. The iron or steel object is coated in a thin layer of zinc. This stops oxygen and water reaching the metal underneath - but the zinc also acts as a sacrificial metal . Zinc is more reactive than iron, so it oxidises in preference to the iron object.
3. Because they are insulators that is they do not conduct electricity. The Brainliest Answer! They can't be used because they are not a good conductor of electricity. And some times they may get fired easily when sparks occur.
4. This is because cardboard is a good conductor of heat energy.so if we cook food in cardboard utensils, the cardboard will burn and turn into ashes.
5. Because they are non metal and do not have property of ductility . The Brainliest Answer! we can't draw wires from coal or wood because the are non-metals.... they do not posses the property of ductility...
6. White phosphorus is highly reactive, and spontaneously ignites at about 30°C in moist air. It is usually stored under water, to prevent exposure to the air.
7. copper metal when exposed to air turns in green in colour due to corrosion. ... It loses it shine due to formation of a green coating of copper hydroxide and copper carbonate on the surface of the object.
8. When Zinc granules are kept in copper sulfate solution the blue color of the copper sulfate solution turns colorless. This because the zinc is more reactive than the copper metal in reactivity series. This means that zinc metal can easily displace the copper metal from its salt to form aqueous solution of zinc sulfate.
hope so it helped you.
