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.
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 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.
Why copper wire is appropriate choice to secure magnesium strip?
Copper can't be dessolved by the hydrochloric acid.
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?
The ISBN of The Burning Wire is 1439156336.
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 wire is used to spread the heat from a Bunsen burner?
MAGNESIUM
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.
What are anodes made of?
It is made out of magnesium or aluminum that form around a steel core wire.
Is bending a metal wire a chemial or phyiscal change?
Physical. The metal wire is still a metal wire after the change.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
