big idea of energy

The big idea of energy for this case is:

the electron in the iron element must equal to the amount in the sulfur so the element of iron looses 1 electron and the sulfur gains 3 electrons so it is equal. this is what happens during the reaction.

Separation

Iron sulphide can be separated using methods such as:

FILTRATION: Using filter paper to separate the iron from the iron sulfide.

MAGNETIC:Using a magnet to separate the iron from the iron sulfide

The reaction

The reaction between iron and sulfur happens when they are put into a test tube and heated over a Bunsen burner. This turns into iron sulfide.

Sulfur

Iron

Sulfur is a yellow element which is not magnetic

Iron is a silvery-grey element which is magnetic

Particles

Iron Sulphide

When mixed together, they create iron sulfide which is a black compound that is not magnetic

Iron and sulfur react by bonding together. iron particles mix with sulfur particles to create iron sulfide. it is a solid so all the particles are arranged in a regular pattern and close together. there is the same number of particles at the beginning and end of the reaction. this is because they combine together s two particles will make one.

The iron and sulfur reaction

This presentation will explain how iron and sulfur react when put together. This presentation will include detailed descriptions, pictures and a video which will make it easier to understand.

QUIZ TIME...

Equation

=

Fe (iron)

Q1: What is the symbol for iron?

Q2: What colour is the compound of iron and sulfur?

Q3: What two colours was the flame in the video?

Q4: Can you seperate the iron sulfide,

if so, how?

Q5: How many electrons will the sulfur gain

in the big idea of energy?

Fe

S

S (sulfur)

=

Fe + S = FeS

Answers...

Iron + Sulfur = Iron Sulfide

Q1: Fe

Q2: Black

Q3: Blue and red

Q4: Yes, with filterationn and magnetic force

Q5: 3 electrons.

A big well done if you got it all correct!

this video will show how the reactions actually looks when taking place:
