Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
You are given a hammer a battery, a bulb, wires and switch(a) How could you use them to distinguish between samples of metals and non metals?(b) Assess the usefulness of these tests to distinguish between metals and non-metals
Students can develop alternative conceptions (commonly called misconceptions) inrelation to some core concepts in chemistry. Consider each of the following ideasexpressed by students and suggest how you would address these incorrect ideasthrough experimental work and class discussion:(i) Sugar (e.g. glucose) and salt (e.g. NaCl) both dissolve in water and thereforeboth are ionic compounds.(ii) Breaking bonds releases energy.(iii) Adding reactant A to reactant B will always produce the same products asadding reactant B to reactant A.(iv) In the reaction of Fe + S --> FeS, adding 10 g of Fe to 10 g S will produce 10g of FeS.
