Does a homogeneous mixture have visible particles?
Visible particles would be heterogeneous elements of a mixture. A truly homogeneous mixture would have no visible particles. However, you could still have an approximately homogeneous mixture with visible particles, evenly distributed throughout the mixture.
What kind of mixture can be separated using decantation?
immiscible heavy solid particles in a liquid which could settle down when mixed together
What is the difference between colloid solution to colloid mixture?
Well they are the same thing because a solution is a type of mixture. If there had to be a difference a colloid solution is when particles are mixed as a colloid in water but a colloid mixture could be anything: a gas colloid, a liquid colloid or a solid colloid. Or any of those three mixed together! It is complicated but basically the difference is that one is particles spread thought mixture and one isn't. Hope it helps :)
How can you use particle size to separate a mixture?
Depending on the sizes of the particles, you could use a funnel with filter paper, or perhaps a screen sieve.
How could you make sure that more particles have the activation energy in a chemical reaction?
The easiest way to overcome most activation energies is to heat the reaction. And the best way to make sure heat is evenly distributed so that more particles can use this energy is to stir the reaction mixture.

Can a mechanical mixture have both solids and liquids in it?
Mechanical mixture: When two or more different materials are mixed together but are visibly not wholly one, like sand and stones on a beach, or milk and cereal in a bowl, a mechanical mixture is created. Another name is "Heterogeneous mixture". These mixtures are without definite composition, and have several component parts that can mechanically separated from the rest.So therefore, yes. a heterogeneous mixture is also called a mechanical mixture.Wow.I searched this question up for a friend for our science test.Glad I could answer :D
What mixture is composed of particles of two or more substances that distributed evenly amongst each other?
I think I gather that you mean solution. A solution is when for example a salt is dissolved in water. Water is known as the solvent. Although the salt ionizes and interacts with the water, this best fits your description. The fills the spaces part, you could be talking about immulsions, whereby two immiscible (non-mixing) liquids, such as oil and water, or dichloromethane and water when shaken together can form a temporary suspension (appear miscible).

Two teaspoons of salt are mixed with water and the particles are spread very evenly .what is this mixture called?
If you did this the salt would probably dissolve. The mixture is a solution.
Is fruitcake a mixture or solution?
Fruitcake is a mixture. Adding fruit in a cake could be a mixture. (Your welcome)
What does a white blood celll do?
A white blood cell is part of the immune system. You could think of a white blood cell as a body guard for your body against infectious diseases and foreign particles.

The easiest way to overcome most activation energies is to heat the reaction. And the best way to make sure heat is evenly distributed so that more particles can use this energy is to stir the reaction mixture.
Is gravel a heterogeneous mixture?
Gravel only refers to the size of a rock, which has a range of about 2mm-65mm on its largest side. A gravel driveway, for example, could be made from either homogeneous gravel (all from the same rock type) or it could be a mixture of rock types(heterogeneous).
If you have a mixture made of two substance one with a higher density than other how could you separate the substance in the mixture?
Winnowing. Run the powder through a sifting grid, and allow it to fall into a box below. Set up a fan to blow sideways. The dense particles are more likely to fall into the box, while the less-dense particles are more likely to be blown off to the side. You will probably need several iterations of this.
