Why was the magnesium put in a copper basket? (why not some other metal? )

Explanation:

According to the reactivity series, it is known that a more reactive metal is able to displace a less reactive metal when both of them are present together.

So as per this series, magnesium is more reactive than copper. Hence, when magnesium is placed in a copper basket then copper is unable to displace magnesium as it is less reactive in nature as compared to magnesium.

Therefore, no chemical reaction will take place. That is why, magnesium is put in a copper basket.

heat or electricity in the atmosphere- c.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
