Chemistry: Advanced
Cells, kinetics, coordination compounds and organic chemistry: worked out step by step.
What you'll learn
- โฆCalculate a solution's molarity, molality and mole fraction, and explain why only molality stays fixed when temperature changes
- โฆUse Raoult's law and colligative properties to find a freezing-point depression or boiling-point elevation, corrected by the van't Hoff factor
- โฆCalculate a galvanic cell's standard EMF from two electrode potentials and use the Nernst equation away from standard conditions
- โฆPredict the products of electrolysing a common aqueous solution and identify the redox half-reactions inside a battery or a rusting metal
- โฆFind a reaction's order from experimental data and calculate a first-order reaction's rate constant or half-life
- โฆExplain why raising the temperature speeds up a reaction, using activation energy and the fraction of effective collisions
- โฆExplain why transition elements show variable oxidation states and coloured ions, and name a coordination compound with its central metal's oxidation state
- โฆTell a coordination compound's isomers apart, and predict whether a haloalkane, haloarene, alcohol or phenol reacts by substitution or as an acid
- โฆUse Tollens' test to tell an aldehyde from a ketone, compare an amine's basicity by type, and compare DNA with RNA
