Solution Details
What is the solute in a solution?
The smaller part that gets dissolved.
What is one method of separation, without tools?
Sorting, Evaporation, Distillation, Sorting, or Settling.
Why can't we separate solutions?
Because they're chemically bonded.
An O₿JECT being cold makes the particles ___.
"Slow down."
How do you purify a valuable ore, like gold?
By using chemicals to extract the gold from the rock, which comes out as waste.
What is the universal solvent?
Water.
What is distillation?
Using evaporation, but having something above the liquid to catch the evaporated liquid, separating the liquid while keeping it.
What is gravel considered?
A Mechanical Mixture
A gas has particles that are different from a liquid or solids in what way?
Their particles have a more flexible shape, and changeable volume.
What is produced when we extract uranium from the ore?
It produces chemical wastes that are left over to contaminate things like water, air or food.
Why is sugar soluble in water?
Because the water particles attract the sugar's particles, breaking them down.
Why can't we separate a solution with simple separation tools?
Because the particles have been dispersed, which would require a more complex device, like a Centrifuge, or Distillation device.
Why does a cold solvent dissolve the solute slower than usual?
Because the solvent particles move slower, making the particles collide less.
Why do gases appear invisible usually?
Due to the particles being spread apart.
How does an oil spill contaminate the water, and how do we remove it?
It creates a layer of oil on the waters surface, and we remove by a long process with many absorption and other tools.
How does a solution work? Explain with details.
By a solvent breaking down, or mixing with the solutes particles, binding them together, or mixing them together.
Explain the difference between a Mechanical Mixture and a Solution.
A solution has a solute that's dissolved, or mixed thoroughly into the solvent that are typically homogenous, while a mixture has multiple, separational parts that are heterogenous.
What is a mechanical mixture? What makes this different from a solution?
A mixture of different objects, or similar objects that are in no way chemically bonded. Solutions are chemically bonded and sometimes homogenous, while mechanical mixtures are always heterogenous.
Use the particle theory to explain why cold particles slow down
That heat leaving the object takes away the energy within the particles, making it stop.
Why do we have to use chemicals to purify an ore?
Because the chemicals are more efficient, better quality, and because they're good at breaking strong chemical bonds.
What is the difference between saturated, unsaturated and supersaturated mixture?
Saturated - Full, cannot hold more solute.
Unsaturated - Partially Full, or empty. Can hold more solute.
Supersaturated - Taking a Saturated Solution and heating it up to add more solvent. Unstable.
Why is ____ the universal solvent?
Water, and because its structure of Oxygen and Hydrogen allow it to have both a negative and positive charge, which attract the Positive and Negative charges of other particles, breaking them down.
What are three ways to tell the difference between a solute and solvent?
• The solvent has more mass than the solute.
• The solvent will not completely dissolve.
• Most solvents are in liquid, while solutes are gasses, solids, or also liquids.
Explain each rule of the particle theory with detail
Everything is made up of particles, Particles are always in motion, There is always space in between particles, Each particle is attracted to each other, Heat makes particles speed up, and that All particles are identical
What is the importance of purifying ores?
Because it increases the quality of the mineral itself, such as gold, making it look much nicer.
or
Because it enhances the performance of the mineral, making it better, like uranium, which becomes more energy-producing.
