chemistry AS and M1 questions

[fahadii92]

Aoa!
1.when examiner asks abt reagent we have to mention in general like H/Cr2O7 2- or can we mention potassium dichromate 7???
2.is ligand in our course?
3.does use of electrostatic force b/w ions and electrons or mettallic bond better words for forces in metals , bcuz examiners always mentions metallic bond even when forces is wat asked abt
4.in changing of SO2 to SO3 in atmosphere does NO acts as catalyst or NO2.
5.how to construct ionic equations, give a link or sumthing

M1,
1.S10 q43 Q7 part 2 and 3,, plz help me on that

 

[fahadii92]

two more Qs plz , first one is that do dilute and conc. hot K2CR2O7 reacts with alkenes just like potassium do ??
secondly does we have to add H positive ion in hydrolysis reaction???

1) You HAVE to mention its acidified ie writing it as H+/cr2o72- is better than writing potassium dichromate, or mention acidified..so you wont lose a mark.
2)No, it's not in AS
3)Your question doesn't really make sense, If the substance given is a metal, write about the metallic bonding AND the forces present, it also depends on the no. of marks for the question!
4) SO2(g)+NO2(g)------>SO3(g)+NO(g) Though you only need to know that during Contact process it's v2o5
5)I dunno any link, but I'll try posting on how to do them by tomorrow
About the other questions, its not potassium, its Manganate ions, No they do not react similarly, it's just in the case of primary & secondary alcohols being converted to aldehydes & ketones respectively.
& I'm not so sure about the H+ part, I'll make sure & tell you later!
