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 would you see if you dropped a piece of magnesium ribbon into some copper sulphate solution in a test tube?
If you drop a piece of magnesium ribbon into copper sulphate solution, you would observe a redox reaction where the magnesium displaces the copper in the solution. This results in the formation of copper metal and magnesium sulphate, with a color change from blue to colorless as the reaction progresses. Additionally, there may be bubbling and fizzing observed as the reaction occurs.
What happens to a piece of magnesium when it is heated?
it become ductile
What would happen if you put iron into a blue copper sulphate solution?
There would be copper deposited in the piece of iron and the solution would show a color change from pale blue to pale green.
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
How can you obtain copper from copper sulphate?
Place a piece of aluminum wire into a copper sulphate solution. Aluminum will replace the copper in the copper sulphate and copper will come out of solution and form along the aluminum wire, actually replacing the atoms of aluminum. The chemical equation is 2Al(s) + 3CuSO4(aq) ---> 3Cu(s) + Al2(SO4)3(aq). This kind of reaction is called a single replacement or single displacement.
How do you get magnesium oxide?
Burn a piece of magnesium (just did an assessment on that)
How tp prepare magnesium acetate?
To prepare magnesium acetate, you can react magnesium oxide or magnesium hydroxide with acetic acid. Start by adding magnesium oxide or hydroxide to acetic acid in a controlled manner while stirring until the reaction is complete. Filter the solution to remove any insoluble impurities, and then evaporate the solvent to obtain solid magnesium acetate.
What would you see if a piece of magnesium ribbon reacts with dilute hydrocholric acid?
When a piece of magnesium ribbon reacts with dilute hydrochloric acid, you would observe effervescence (bubbling) as hydrogen gas is released. The magnesium ribbon would dissolve in the acid, producing magnesium chloride solution. The solution may also become warm due to the exothermic nature of the reaction.
What happens when a piece of magnesium is dropped into a beaker of hot water?
The magnesium reacts with the water to produce magnesium hydroxide and hydrogen gas. This reaction is exothermic, meaning it releases heat. The hydrogen gas can be collected and tested by igniting it to see its flammability.
How do you separate copper sulphate from copper?
Copper sulphate is a compound, so copper must be obtained through a chemical reaction. To obtain copper from copper sulfate, do the following: Place a piece of aluminum wire into a copper sulphate solution. Aluminum will replace the copper in the copper sulphate and copper will come out of solution and form along the aluminum wire, actually replacing the atoms of aluminum. The chemical equation is 2Al(s) + 3CuSO4(aq) ---> 3Cu(s) + Al2(SO4)3(aq). This kind of reaction is called a single replacement or single displacement.
When a piece of magnesium ribbon is placed into beaker containing hydrochloride acid bubbling is of served a chemical change?
When magnesium ribbon is placed in hydrochloric acid, a chemical reaction occurs, resulting in the formation of magnesium chloride and hydrogen gas. The bubbling observed is due to the release of hydrogen gas as the magnesium reacts with the acid. This reaction is characterized by the magnesium dissolving and the solution becoming warmer, indicating an exothermic process. Overall, the visible bubbling and changes in the solution confirm a chemical change has taken place.
