COPY PASTED FROM 1st TOPIC
Law of conservation,
* Mixture, homogeneous mixture, heterogeneous mixture,
* Chemical reaction, reactants and products; Main types of chemical reactions (combination, decomposition, displacement,
double displacement, red-ox)
* Classification of compounds (acid, base, salt, oxide)
* Atom, ion, molecule
* Dissociation; Electrolyte, Nonelectrolyte
* Chemical bond (ionic, covalent)
Homeostasis
Explain what it is and, main tasks and parameters to stabilise
(Not that important)
Role of chemistry in modern medicine
Health care
Laboratory tests
Drug devolopment
Materials and accessories
(Barely mentioned) What are dispersion systems?
What category are they in?
One substance is called the dispersion phase and is dispersed in the form of tiny particles in another substance called dispersion enviroment. Each of the substances can be in any physical state.
In Hetorogene mixtures!
2 types of mixtures?
Explain solute, solvent and solution shortly
Explain in swedish?
Tänk lika löser lika. Polära löser polära och opolära löser opolära.
Vad är electrolytes?
Elektrolyter är kemiska ämnen som när de löses i vatten bryts ner i positivt och negativt laddade joner. De vanligaste elektrolyterna i kroppen är natrium, kalium, klorid, kalcium och magnesium.
Look at the picture and remember these concepts
What is ion?
Ions are multiple atoms are linked together but positively or negatively charged particles = ionic bonds.
