Physical and chemical change 🧏🤫
Use quizlet!
What is the law of conservation of mass?
Total mass of reactants is equal to the total mass of products
Why is this, Total mass of reactants is equal to the total mass of products (conservation of mass)?
In reactions atoms cannot be created or destroyed they are simply rearranged
SAY EVERY SINGLE PEICE OF EQUIPMENT IN FILTRATION AND HOW IT WORKS.
Filter paper, Beaker, Mixture, Residue, Filter funnel, Conical flask, Filtrate
Liquid particles are small enough to pass through filter paper
Solid particles are to large to pass through filter paper and so stay behind

Evaporating basin, Wire gauze, Tripod, Bunsen burner, Heatproof mat
Evaporating is used to separate soluble solid from a liquid

What does Soluble mean?
A solid that does dissolve in water
What does Insoluble mean?
A solid that does not dissolve in water
What does Solute mean?
The solid dissolved in water
What does Solvent mean?
The water in a solution
What does the Solution mean?
This is made by dissolving a solid in water
SAY EVERY SINGLE PEICE OF EQUIPMENT IN SIMPLE DISTILATION AND HOW IT WORKS.
Thermometer, Liebeg condenser, Round bottom flask, Solution, Water out, Water in, Heat source, Distillate
Simple distilation is a physical method which is used to separate a liquid from a soluble solid in a solution
Simple distilation works because the dissolved solute and solvent have very different boiling points
There are two main processes that happen during simple distillation;
Boiling/evaporation (liquid to gas)
Condesation (gas to liquid)

Example, producing pure water from salty sea water solution
