a pure substance is 1 substance, and has only one kind of atom or molecule.also, only made up of 1 type of matter.
a mixture is made up of many substances, and has 2 or more types of matter.It can also be separated.But, it might not be easy to separate.
*in a boring voice says* have a great day,come again*sighs*
Neither, try again.

The particle theory of light, which suggests that light is made up of small particles called photons, was first proposed by Albert Einstein in 1905 to explain the photoelectric effect. This theory revolutionized our understanding of light and helped to explain phenomena that the wave theory of light could not account for. Today, the particle-wave duality of light is a fundamental concept in quantum mechanics.
Yes, the Particle Model can explain refraction by considering light as a stream of particles (photons) that change speed and direction when passing through different mediums, causing the bending of light rays.

You can use the particle theory to help explain what happens when solutes dissolve. The particle theory states that there are spaces between all particles. This means that, in a sample of water, there are many water particles, but also many empty spaces. When you look at sugar. The sugar dissolves, the sugar particles separate and mix with the water particles.

A particle model can be used to explain the reaction between iron and sulfur by illustrating that iron atoms react with sulfur atoms to form iron sulfide molecules. In this reaction, the iron atoms lose electrons to the sulfur atoms, forming ionic bonds in the iron sulfide compound. The particle model visualizes the rearrangement of atoms and the formation of new compounds during the reaction.
it shows that there is space between the model and iron is big and it attracts
Sound is a series of vibrations. In a solid they travel in waves from particle to particle, causing the solid to make a noise.
Yes. Light has both particle and wave properties.
