OHCH2CONH2 PRODUCES NH3 WHEN HEATED WITH NAOH CAN ANYONE TELL ME HOW AND WHAT GROUPS ARE RESPONSIBLE FOR THAT

only group 1 sulphates and carbonates are solubleAre all sulphates and carbonates soluble ??
solubility decreases down the group 2 bec enthalpy change of hydration and lattice energy decrease. use this link :-- http://dl.clackamas.cc.or.us/ch105-03/solubili.htmAre all sulphates and carbonates soluble ??
no problems about the other one...hydroden halides are Reducing agents .....and power of reducing agent increases down the group ..... HCl<HBr<HI.......
p.s the non metals (helogens cl,br,I) are not reducing agents ...they are O.A .....metals are R.A...
and lastly i didnt get what you were saying above but i tried to explain what i have understood
are u sure wouldn't every term in the equation just cancel out each other tbh i tried it that way too....You just have to try each option to see if it works, using the given stoichiometric equation.
Going straight to B: If you had two moles of P originally and then x mol of R were present at equilibrium, then you'd expect 2x mol of Q to be formed at equilibrium. Furthermore you'd use up 2x mol of P, so that there is 2-2x mol of P at equlibrium. If you add the total: 2-2x+2x+x=2+x
no problems about the other one...
I asked my teacher 2day n she said that Oxidising ability decreases down the gp 7, so iodine is a reducing agent
Thanks anyway...
u are saying it wrong .....
look if u go down the group ,the oxidising ability increases .........just confirm this once again
no problems about the other one...

for question 1Guys i have a test tomorrow and i have few questions. http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_w06_qp_1.pdf
Questions 1, 9, 32, 37. Thanks!
The Kc expression for reaction I ishttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s07_qp_1.pdf
Q-9 stuck bad......help please
http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s04_qp_1.pdf
can anyone solve q 28 i dont get it please
answer should be C
X is clearly bromine not iodine
thnx that helpedX is clearly bromine not iodine
Y has low melting point, and even low density, thus it must be sodium not Aluminium (aluminium cant melt in tht low temp)
Z seems to be a metal so yea Mg
