A mixture of iron fillings and sulphur is heated in a test tube give the name of the compound formed.
write the chemical equation of the reaction which took place
method of preventing iron from rusting​

Explanation:

When the iron filling is heated with sulphur, a compound called iron sulphide is formed. The compound formed by heating iron filling with sulphur powder is iron sulphide. Therefore the answer is iron sulphide, FeS.

Explanation:

When the iron filling is heated with sulphur,iron sulphide is formed. The equation of the reaction that took place is;

Fe + S → FeS (heat).

The rusting of iron can be prevented by painting, oiling, greasing or varnishing its surface and galvanizing

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.
