What are the difference between a substance's physical properties and its chemical properties?
Chemical properties involve reacting with another substance. IE: burning of magnesium requires oxygen after which it is no longer magnesium. Physical properties do not. IE: metals are malleable, some very malleable, like copper wire can be bent with your hand. BUT it is still copper wire.
What type of chemical reaction takes place when a magnesium wire is burnt in air and write chemical equation for the same?
When magnesium oxide is burnt in air, an oxidation of the magnesium and reduction of some of the oxygen in the air occurs according to the equation:2 Mg + O2 -> 2 MgO.
Is heating a chocolate chemical change?
Yes, burning of a sparkle is a chemical change because once sparkle has changed its form it cannot come into its previous form. For understanding you can also take the example of cooked rice which once cooked cannot be raw again.
What is the colour of pure magnesium wire?
like goldish silver
What is physical properties of magnesium wire heated?
When magnesium wire is heated, it undergoes several physical changes. Initially, it expands due to increased temperature, which causes the atoms to vibrate more vigorously. As the temperature rises further, magnesium can ignite and burn with a bright white flame, producing magnesium oxide. This combustion alters its physical state, transforming the wire into a powdery ash-like residue.
How might a burning magnesium wire be used in a commercial application?
To produce an intense white flash.
What is the ISBN of The Burning Wire?

How many pages does The Burning Wire have?
The Burning Wire has 432 pages.
When was The Burning Wire created?
The Burning Wire was created in 2010-06.

What happen if copper wire dip in solution of magnesium chloride?
When copper wire is dipped in a solution of magnesium chloride, no significant reaction occurs because copper is less reactive than magnesium. The magnesium ions in the solution do not displace copper from its metallic state. As a result, the copper wire remains unchanged in appearance and composition. However, if the solution were to contain a more reactive metal, such as zinc, a displacement reaction could occur.
What type of chemical reaction takes place when magnesium wire is heated?
When magnesium metal wire is heated in open air, an oxidation-reduction reaction takes place between the magnesium and the oxygen in the air. The magnesium is oxidized as the oxygen is reduced. The product of this reaction is magnesium oxide, MgO. Note that this reaction can also be deemed a combustion reaction, which is a specific type of redox reaction which involves the production of heat and sometimes light.
Why copper wire is appropriate choice to secure magnesium strip?
Copper wire is a good choice to secure a magnesium strip because copper does not react with magnesium, so it will not interfere with the chemical properties of the magnesium strip. Additionally, copper is malleable and ductile, making it easy to wrap around and secure the magnesium strip in place.
