Introduction - TN Flashcards
What is the change from gas to solid called
Deposition
Diatomic Molecules
Iodine
Bromine
Chlorine
Fluorine
Oxygen
Nitrogen
Hydrogen
Monatomic
Single atoms
As you steadily add energy to a substance why is there a plateau of temperature every so often
Because energy is required to break bonds between the atoms
Describe the physical looks of Iron
Describe the physical looks of Sulfur
THEN
Describe the physical looks of Iron sulfide
Grey , Solid, Magnetic
Yellow, Solid, Non-magnetic
Grey-brown, Solid, Not magnetic
Describe the physical looks of Sodium
Describe the physical looks of Chlorine
THEN
Describe the physical looks or sodium chloride
White/rlly pale grey, Solid
Green gas
White solid
FeS
FeSO4
What are these two compounds called
Iron sulphide
Iron sulphate
How to draw a line of best fit
Straight line with the same number of points on each side
Diffusion experiment (tube)
Ammonia solution on cotton wool at one end
Hydrochloric acid on cotton wool on the other side
They react to form a ring of Ammonium chloride
Which is closer to the hydrochloric acid because it has a greater mass so the particles move slower than the ammonia solution
Diffusion
Movement of particles from an area of high concentration to an area of low concentration
Brownian Motion
The random movement of particles
Saturated
a solution in which on more solute can disssolve
suspension
a solid present in a solution because it did not dissolve
where on a graph is a solution saturated
anywhere on the line
Solubility
how much of a substance able to dissolve in a solvent at a given temperature
