What happens if magnet is placed next to copper?
When a magnet is placed next to copper, the magnetic field of the magnet induces an electrical current in the copper due to electromagnetic induction. This effect is known as eddy currents, causing the copper to become magnetized temporarily.
When an iron nail is placed into a solution of copper sulfate what happens?
In this case, copper ions from the copper sulfate solution will react with the iron in the nail through a redox reaction. The iron will gradually dissolve into the solution, while copper ions will deposit on the surface of the nail, forming a layer of copper on the nail.
When zinc metal is placed into a solution of copper sulphate a pinky brown metal is formed but when a piece of silver metal is placed into another solution of copper sulphate no change is observed Why?
Silver is lower in the reactivity series than Zinc and therfore cannot displace the Sulphate from the Zinc. But on the other hand zinc is higher than copper, and when displacing the sulphate from the copper it changes colour due to the reaction. Reactivity series(metals): Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Silver Gold Platinum
Would a bar of copper contract if you placed it in a refrigerator?
All metals will expand and contract to some degree depending on the temperature.
What happens on placing iron nails in a beaker containing Copper Sulphate?
when iron nails are kept in a beaker containing copper sulphate displacement reaction takes place.Iron is more reactive than copper so it displaces copper from the copper sulphate solution.Thus it becomes iron sulphate+copper
What will happen if a candle is placed in a basin of water covered with a cup?
If burning, the candle will use up all the oxygen and go out.
Why does a candle go out when burning in a sealed jar?
A candle requires oxygen to burn, and when placed in a sealed jar, the oxygen supply is depleted, leading to the candle extinguishing. This happens because the flame consumes the available oxygen, creating a vacuum that eventually snuffs out the flame.
How does a candle look like it is burning inside a glass of water?
When a candle is placed inside a glass of water, the water absorbs the heat produced by the flame. This heat causes the water to evaporate and rise above the flame, creating the illusion that the candle is burning inside the water. In reality, the candle is burning above the water level.
If you lift the glass tumbler which is placed over a burning candle to 1cm height what hapens?
Lifting the glass tumbler placed over a burning candle to a height of 1cm could disrupt the airflow around the candle, affecting its ability to receive oxygen. This may cause the candle flame to flicker, decrease in size, or even extinguish depending on how much air is allowed to reach the flame.
Why does a candle go out when dry ice is placed near it?
Gaseous carbon dioxide is released and this gas doesn't support burning.
What happens when copper is placed in acid?
When copper is placed in acid, a chemical reaction occurs where the copper reacts with the acid to form copper ions and hydrogen gas. This reaction results in the copper dissolving in the acid and producing a blue-green solution.
What happens when iron is placed in copper sulfate solution?
When iron is placed in copper sulfate solution, a chemical reaction occurs where the iron displaces the copper in the solution, forming iron sulfate and copper metal. This is known as a displacement reaction.
Why does a lit candle go out when a inverted beaker is on it?
When an inverted beaker is placed over a lit candle, the flame goes out due to lack of oxygen. As the candle burns, it consumes oxygen and generates carbon dioxide and water vapor. When the beaker is placed over the candle, it creates a closed system, limiting the supply of oxygen needed for combustion, causing the flame to extinguish.
What happens if magnet is placed next to copper?
When a magnet is placed next to copper, the magnetic field of the magnet induces an electrical current in the copper due to electromagnetic induction. This effect is known as eddy currents, causing the copper to become magnetized temporarily.
What happens when iron nail are placed in copper sulphate solutions with word equation?
If iron nails are placed in a copper sulphate solution they turn green and rusted which means they become copper plated nails.I think the word equation is :iron + copper sulphate - copper + Iron sulphate.Iron displaces copper
What happens to a piece of copper placed in magnesium chloride solution?
When a piece of copper is placed in magnesium chloride solution, no reaction will occur because copper is less reactive than magnesium. Copper will remain unchanged in the solution.
What did Joseph Priestly contribute to the discovery of photosynthesis by using a candle?
he put the candle in a tube until it burnt out, then placed a mint sprig in the tube. 27 days later he lit the candle again using sunlight and it burnt perfectly leading him to believe that the mint replaced whatever was lost when the candle was burning.
