Reactivity series of metals an order of reactivity, giving the most reactive metal first, based on results from a range of experiments involving metals reacting with oxygen, water, dilute hydrochloric acid and metal salt solutions Extraction of metals Most reactive metals are extracted from their ores by electrolysis of a molten compound. Iron ore blast furnace Fe2O3 + 3CO → 2Fe + 3CO2 - Carbon is higher in the reactivity series than iron and is therefore able to remove the oxygen from ...

directionality problem - a problem encountered in correlational studies; the researchers find a relationship between two variables, but they cannot determine which variable may have caused changes in the other variable observer bias - systematic errors in observation that occur because of an observer's expectations selection bias - in an experiment, unintended differences between the participants in different groups; it could be caused by nonrandom assignment to groups confirmation bias -...
