ICSE − Q & A

Could someone please tell me if we have to give equations when we give a chemical test  to  distinguish between X and Y? The pupil analysis doesn't include equations but in school but we've always had to include them in our answers.

@Tedgreen Bro why you deleted the post?

hello frnds
I was a frequent user of this part of respapre because I felt some doubts ver useful and also to post my doubts but now the pattern has changedand I amnot gonna use this any more . because an idiot is posting all shit which is wasting my time 
so guys all the best for ur exams!!!!!

your frnd,

Guys this whoeven is no doubt a psychopath who probably snorts a line of coke before posting this shit. (Bonus fact: His mom sells herself and all that dope in some shady alley)  But just his artwork is an indication of how perverted his mind is and how twisted his mentality towards women is. While these days we have so many campaigns on women empowerment active in our country,  such disgusting people do exist. Let us all try to write to the developers of this site to ban this abhorrent animal ( he is not even worthy of being called a human being)

Again, Hello;
I am leaving this page Forever- I mean forever. I just used to come here to answer doubts or solve good questions, (post predictions also ;) ) but Today I realised that all this is unnecessary when I am the source of all trouble here. 
Maybe this is a very coward step but still it would be satisfactory to the CYBER BULLY as well as many others here. 
Some people here assumed that I wanted 'attention' through the last two messages I posted here without even thinking about my situation, the number of complains I have sent to respaper, the thousands of messages I received from that person like "I want you to fail" + abusive words and language. 
Others here went to the extent of calling it 'a plot twist' - Please keep in mind that I am not so cheap and wouldn't even think/dream of posting such things here. 
@Tedgreen you too assumed that I was him #Unexpected. 

AT the same time, 
All the best for the rest of the exams and 
also send me some Computer A. doubts if you have.

I repeat, I wouldn't post anything here again - neither my expected score nor answers to questions or anything else. 

I would surely be there answering in prelim papers or other papers or inbox messages. 

BYE and Thanks for the great and amazing revert.

M is a metal above h2 in the activity series and it's oxide has the formula M2O. The oxide when dissolved in water forms the corresponding Hydroxide which is a good conductor of electricity in the above context answer the following : 1) how many electrons are there in the outermost shell of M 2) name the group to which M belongs 3) state the reactions taking place at the cathode

here is some more imp stuff:

reactive metals like sodium and potassium is kept in kerosene oil as they react with moisture and air
process used for enrichment of sulphide ores- froth floatation
formula of slag-casio3
formula of gangue-sio2
flux-caco3
when a mixture of AL powder and iron oxide is ignited , the latter is reduced to metal and the process is called aluminothermy.
