i dunno i wrote teriary alcohol....r u sure its an acid?CH3COOC2H5.. Ethanoic Acid
yup it was ethanoic acid . i double checked it. the alcohol formed after hydrolyses would be oxidisedi dunno i wrote teriary alcohol....r u sure its an acid?
so MgO is right? i wrote the same wid 6.5 pH nd white flame ...bt im confused? dey askd fr colord flame so ?

White is not classified as a colour in the mark schemes.Well if they asked for colored flame.. I don't think they mean a white color flame included.. since then that will include all the oxides.. any thoughts A star?

I remember the examiners refuted Mg once in the pastpapers.
u needed to state colour of flame right it only discluded few elements magnesium might be accepted its upon the examiners discretion and upon the ms i guessWell if they asked for colored flame..

Examiner wants covalent chloride and so the answer is Al .. Nacl is an ionic compoundhey nacl conducts too!
muddy not the only answerExaminer wants covalent chloride and so the answer is Al .. Nacl is an ionic compound
the last one was Al toowas any of the others Al too? or just one? i remember writing both Na and Al
yes, this is correct.i wrote IClhas the strongest dipole as the difference between the electronegativity of chlorine and iodine is the greatest
is that right?
okay....the last one was Al too
well i wrote phosphorus didnt go to any risky element what made u guys choose a risky one:/
it said dissolved to form a solution but my friend HCl also disociates when dissolves in water it also reacts toform H3O and Cl- so in this respect no element shown was rightGuys I wrote Na :/ not appreciating that a co-valent chloride was asked :/ and Al is wrong . I collected from diff Mark schemes that Na and Mg dissolve in water but Al to S all chlorides react!
It was v.v.tricky H seems to fit all the conditions, many of us would not even think of that!
I think i wrote Si for that is it write?Guys I wrote Na :/ not appreciating that a co-valent chloride was asked :/ and Al is wrong . I collected from diff Mark schemes that Na and Mg dissolve in water but Al to S all chlorides react!
