Is soft water a colloid?
Soft water would not be considered a colloid. This is because the definition of a colloid describes it as the fine dispersion of a substance in another without a new solution forming.
How do solutions and colloidal dispersions compare in particle dispersion?
In colloids, the dispersed substance is not dissolved, but exists in small microscopic packets usually homogeneously dispersed through the medium. A fog, which is small water droplets suspended and evenly dispersed in air, is a colloid A solution contains a solute dissolved in a solvent, in which each individual molecule is discretely separate from all others in a solvent. The solute will usually ionise to multiple constituent parts. e.g. NaCl in water forming Na+ and Cl-. The solvent may also coordinate around the solute, bonding to it via van der Waals forces.
What is an area of crowded particles followed by widely spaced particles?
An area of crowded particles followed by widely spaced particles is known as a density wave. In a density wave, particles are closely packed together in one region, creating a dense area, and then spread out and become less concentrated in another region, resulting in a sparse area. This pattern repeats periodically, forming a wave-like structure.
Why are comet sometimes called dirty snowballs?
Because... they're mainly composed of ice and dust. When they get close enough to be affected by the Sun - the stream of particles forming the 'tail' is formed from ice crystals and dust particles.
How is it possible for a single sedimentary rock to contain rock particles animal shells and minerals that crystalized from water?
The rock particles and animal shells are sediments that were transported, then deposited in the same location; as they subsequently were compacted by the weight of additional subsequent sediment deposits from above, the water between the sediment particles was driven out. As compaction drives the water out, minerals are precipitated from the remaining mineral laden solution which bind the animal shells and rock particles together, forming rock.

How is Dissolving best described?
Dissolution is a physical process; the solute is dispersed or dissociated in a solvent forming a homogeneous mixture.

Why is milk a stable colloid?
A colloid is a mixture that consists of charged (usually negatively) particles that repel each other making it so that they don't collect and separate.Even though milk appears to be a homogeneous mixture, it is a colloid because it has small globules of fat and protein that do not settle out after standing due to the particles (usually negatively) charged particles. These particles repel each other so they do not collect into larger particles that would settle out.However, if you were to add acid to milk, the acid would neutralize the charge and the particles would coagulate and settle to the bottom of the container.so: Milk is a colloid because it has small globules of fat and protein that do not settle out (due to their negative charges that repel each other).Hope I helped-M

Describe how the motion and arrangement of particles in a substance as the substance freezes?
The particles get attracted to each other, forming a solid.
Which subatomic particles are most involved in forming chemical bonds?
Electrons
Why do the components of a colloid not separate?
Most colloidal suspensions have a size small enough not to be affected by gravity and the thermal forces give their motion. In the case of charged colloids, a diffuse layer is forming around the particles, composed mostly by counter-ions (small ions of opposite sign). These counter-ions are subject to attraction toward the surface by the opposite charge and are depleted from the surface by the thermal forces. When two charged colloidal particles approach each other, a repulsive force results, due to the overlap of these diffuse layers. This repulsive force does not allow for the particles to get in contact and aggregate. Without addition of salt or oppositely charged polymers, a colloidal suspension which is not affected by gravity can stay stable indefinitely.
What stops salt crystals from forming when water particles are present?
Salt crystals will not form is the water weight or temperature of the water particles is incorrect.
Before forming sedimentary rock minute particles need to do this for a million years?
settle
What happens to sugar in water in terms of particles?
The sugar dissolves in the water, forming a mixture. The particles diffuse until there is an equal distribution of sugar particles throughout the entire container of water.
