This is separation of a mixture. It does not have a specific name as it's a special case which only works with iron and a few other magnetic metals such as nickel.

What is a technique that can be used to separate molecules in a mixture by subjecting them to an electrical field within a gel?
This is called gel electrophoresis
What is the reaction between sulfuric acid and iron filings called?
chemical reaction.
Which piece of equipment would be best for separating the sand from the mixture?
Depends on the mixture, but if it were sand and water you could use filtration paper or just boil the water to make it evaporate leaving only sand behind. If you wish to take the iron out of the sand grab a magnet and your sand will be clear! This separation technique is called magnesium. If you are separating the sand from a lighter solute (solid) like sawdust use flotation. Place them in water and the sand will drain down to the bottom whilst the sawdust will float on top.
If you stir salt into boiling water is it a mixture called a solution or a mixture only?
no, you would produce a solution
What process happens when wood is transformed to sawdust could it be condensation?
no, as condensation is sweating. I dont know what the process is called.
Is powdered sulphur and iron filings a solution or a mixture?
Solutions are a type of mixture, so it's not really an either/or thing. However, in order to be considered a solution, the mixture must be homogenous, and a mixture of sulfur and iron filings is decidedly not homogeneous on a microscopic level. So it's (just) a mixture, not the specific type of mixture called a solution.
The technique of separating gold from a mixture of gold dirt and sand is called?
Panning.

Two or more substances that have been combined but not chemically changed.?
If you wish to know two substances that do not react when they are mixed, then helium and neon (inert gases) serve as an example.
When to liquids in a mixture have different boiling points they can be separated by?
Two liquids in a mixture with different boiling points can be separated by distillation.

It is called filtering.
A mixture that has different materials that are spread out unevenly is called what?
A "heterogeneous mixture", which alternatively be called an "inhomogeneous" mixture.
When water is the solvent for a mixture the mixture is called?
when water is the solvent for a mixture it is called and aqueous solution.
What is a mixture in which particles are suspended in a solution called?
Such a mixture is called a colloidal solution.
