Question

Plzzz solv it fast no 2 all.... its urgent TOMORROW IS MY EXAMMMMMMMMM....

Answer 1

1) Na2O2 + 2 H2O = 2 NaOH + H2O2
2)Sn + 2NaOH + 4H2O = Na2[Sn(OH)6] +2H2
3)3Cu + 8HNO3 =3 Cu(NO3)2 + 4H2O + 2NO
4)Ag2O + H2O2 = 2Ag + O2 + H2O
5)Na2SiO3 + 8HF
→H2SiF6 + 2NaF + 3H2O
6)MnO2 + 4HCl = MnCl2 + 2 H2O + Cl2
7)BCl3 + 3 H2O = B(OH)3 + 3 HCl
8) KBr + H3PO4 = KH2PO4 + HBr
9)Mg3N2 + 6H2O = 3Mg(OH)2 + 2NH3
10)Sb2S3 + 6HCl = 3H2S + 2SbCl3
11)Ca3P2 +6H2O = 3Ca(OH)2 +2PH3
12)SnCl2 + O3 + HCL = SnCl4 + H2O
13)H3AsO4 + H2S = As2S3+ H2O

hope it helps :)

Answer 2

i) Na2O2 + 2H2O == 2NaOH + H2O2

ii) Sn + 2NaOH + 4H2O = Na2(An(OH)6) + 2H2

iii) 3Cu + 8HNO3 = 3Cu(NO3)2 +4H2O + 2NO

iv) Ag2O + H2O2 = 2Ag + O2 + H2O

v)Na2Si03 + 8HF = H2SiF6 + 2NaF + 3H2O

vi) MnO2 + 4HCL = MnCl2 + 2H2O + Cl2


vii) BCl3 + 3H2O = B(OH)3 + 3HCL

viii) KBr + H3PO4 = KH2PO4 + HBr

ix) Mg3N2 + 6H2O = 3Mg(OH)2 + 2NH3

x) Sb2S3 + 6HCl = 3H2S + 2SbCl3

xi) Ca3P2 + 6H2O = 3Ca( OH)2 + 2PH3

xii)SnCl2 + O3 + HCl = SnCl4 + H2O

xiii) H3AsO4 + H2S = As2S3 + H2O
