Deduce,why,enthalpy,of,lattice,formation,of,caesium,iodide,is,different,to,value,given,,,ANS,-
Not,perfectly,ionic,,not,spherical
Meaning,of,periodicity,,,ANS,-Repeating,trends,of,physical,or,chemical,properties
Period,4,element,with,largest,atomic,radius,,,ANS,-K,,smallest,nuclear,charge,and,same,shielding
Property,of,something,that,reacts,with,an,acid,and,base,,,ANS,-Amphoteric
Explain,why,copper(I),Iodide,is,white,,,ANS,-Full,3d,sub,shell,
So,not,a,transition,metal,as,can't,absorb,white,light
Explain,why,water,isn't,acidic,at,pH=,6.67,,,ANS,-[H+],=,[OH-]
Define,enthalpy,change,,,ANS,-heat,change,at,constant,pressure
Suggest,why,Ca2+,(-1650),value,is,less,exothermic,than,Mg2+,(-1920),,,ANS,-
Ca2+,ion,bigger,charge,to,size,ratio
Weaker,attraction,to,OH-,in,water
Reaction,of,Na,&,H20,,,ANS,-2Na,+,2H20,->,2NaOH,+,H2
P4O10,+,H2O,,,ANS,-P4O10,+,6H2O,-->,4H3PO4
Al2O3,+,H2SO4,,,ANS,-Al2O3,+,3H2SO4,—>,Al(SO4)3,+,3H2O
