small ques

Graphite is an allotrope of carbon, it is simply a different form of carbon where the atoms are arranged in hexagonal layers which slide on one another(giving graphite better electron mobility and thus the ability to conduct electricity). Both graphite and diamond are pure forms of carbon if not treated with any impurities.

Ans 4 is N₂ + 2H₂O if you want balanced eq.

When heating compounds, i first take out the max. no. of water molecules if both H & O are present in it (this works MOST of the times) [6]

4) NH₄NO₂ -----> (aaram se v can get 2 moles water n then only N₂ is left behind) giving 2H₂O + N₂

3) Same way NH₄NO₃ --(heat)---> 2H₂O + N₂O

5) Glycine is an amino acid if am not wrong ; no further details in my knowledge abhi..

Also, decoder is rite fr 6 n 7 too...n i agree with pritish fr the 8th one's explanation..

Q.1) NH₃ + HOCl → N₂ + HCl + H₂O

Q.2) The sodium ions are exchanged by calcium ions. thus, the sodium zeolite is converted into calcium zeolite. again this odium zeolite can be obtained by adding conc. NaCl solution to calcium zeolite.

Q.3) N₂O + H₂O

Q.4) N₂ +H₂O

Q.5) glycine is the simplest amino acid NH₂ - CH₂ - COOH.
So, when its heated it might form cyclic product.

Q.6) NH₃ + HCl

Q.7) NH₃ + CO₂ + H₃O

Q.8) False. agree wid pritish ' s reason.

@aieeee
ans1 wrong
ans2 a bit incomplete

rest all correct...

and thx avik,decoder,pritish,tushar

but still Q1,2 remain unsolved

a)H⁺
b)Ca²⁺
c)SO4 ^2-
d)Mg²⁺

hehe. then its b) and d). i gave Ca²⁺ as the transfer is easier in it as Ca²⁺ zeolite is more easily transformed into sodium zeolite.

still sorry, i missed it out.
