someone pls explain that how the hell is   1/12th mass of 1 carbon atom multiplied by 6.023 * 10^23 give 1 as the product

If both roots of ax^2+bx+a-c =0 are imaginary and a b and c are real numbers and c>-1 then establish relation between a b and c

Guys plz check whether this question is wrong or not :-
In H atom the energy of electron in the nth orbit is given as En = -13.6/n².
Show that E(n+1) - En = -13.6/n²  eV*2 for large value of n.

#By large value of n ---> you can consider n+1 ~ n

1 mole mixture of N2,NO2,N2O4 has a mean molar mass 55.4 on heating to temprature at  which all hte N2O4 dissociate  into NO2 according to raction
(N2O4 double headed arrow 2NO2) and average molar mass becomes 39.6.what is the mole ratio of N2,NO2,N2O4 ????? [ANSWER:0.5:0.1:0.4]

मैं पता करना चाहूँगा की आप लोगो ने कोन कोन सी क्लास्सेस एव कॉलेज में एडमिशन लिया है ??(यह भी बताए की वह इंटीग्रेटेड है या नहीं)

Guys check the official site out. They were so fed up by what happened today that they themselves declared that they will notify 48 hours before the results are declared.

Now, this is really getting frustrating. NO MORE RESULT UPDATES ON THIS Q/A PAGE UNTIL ICSE OFFICAILLY DECLARES IT ON CISCE.ORG. NOW, I SUPPOSE THAT IS CLEAR. NO HOAXES FROM DUMB NEWS CHANNELS OR WEBSITES.

P.S.: mind the caps

I am seriously tired of these fake news getting around regarding the board results. Isn't it becoming really interesting that the exam dates were changed once and now there is much fuss regarding the result announcement dates in this year's icse exam?
