Chemistry Flashcards
Which out of the 3 types of particles are fixed
Solid
Which out of the 3 types of particles can flow
Liquid and gas
Which out of the 3 types of particles can be squashed
Gas
Which out of the 3 types of particles have a fixed volume
Solid, liquid
Which out of the 3 types of particles are the most dense
Solid
What are the characteristics of a solid
Touching
Fixed position
Uniform arrangement
Can vibrate
What are the characteristics of a liquid
Touching
No fixed position
Flow
Random arrangement
What are the characteristics of a gas
Fills container Random arrangement Flows No fixed position Not touching
What are particles moving around described as
Kinetic energy
What is a solid into liquid called
Melting
What is a liquid into gas called
Evaporating
What is a gas into a liquid
Melting
What is a liquid into a solid
Freezing
What is a solid into a gas
Sublimation
What is a gas into a solid
Deposition
What is melting point?
0 degrees
What is evaporation
A liquid is so hot that particles start to SEPERATE to a gas due to the build up of energy
What is condensing
When a gas is so cold the energy starts to break up and making the forces stronger
What is diffusion
Diffusion is the process of changing a high concentration substance to a low concentration substance
What happens if gas is put into a container
It pushes against the walls, and the particles exert a pressure when they hit the wall, creating a pressure
Neutron
No charge
Inside the nucleus
Mass - 1
Proton
Has a charge
Inside the nucleus
MAss - 1
Electron
Negative charge
Mass - 0
Where does diffusion occur
Mostly in gasses, liquids
Where does diffusion happen quicker
In warm tempature (as it increases the energy) and in gasses (gas has more energy and moves quicker)
What is a mixture
Two or more substances mixed together but not chemically joined
What is a solution
Special type of mixture made when a solid dissolves and mixes with a liquid
What are suspensions
Where solids are insoluble and mixed with a liquid
Solvent
A liquid with dissolves a solute
Solute
A soluble solid which can be dissolved in a solvent
Soluble
Can be dissolved in a solvent
Filtration
Seperating substances to create a filtrate and residue
Evaporation
A way to separate a solid dissolved in a liquid by the liquid turning to a gas
Chromatography
Used to separate different substances dissolved in the same solvent
Liebig condenser
Used to purify water
Metal properties
Shiny Sonorous Malleable Dense Electricity conductor High melting point Ductile
Non metal properties
Full
Low melting point
Brittle
Poor conductors of heat
How many types of atoms are elements made of
1
How many types of atoms are compounds made of
2 or more chemically joined
How to write simple compounds
Write the metal
Write the non metal changing the ending to ide
How many types of atoms is a mixture made of
2 or more mixed together not chemically
Compounds
Contain more than 2 elements
How to write 2 elements plus oxygen
Write the metal
Ending of the non metal changes to ate
What are the signs of a chemical reaction
Facts
What is the neutralisation word equation
Acid + base = salt + water
